Keeping the object and lights stationary is key as you've shown. I'm going to try a poor person's version with a large foam core cutout circle as my guide for positioning each 10 degree shot. Very encouraged by your success with this.
This is exactly what I was considering when talking to a friend. Good to see that the lazy Susan bearing is a viable option. I’ll definitely be looking at this as a point of reference for my own, unsure on scale yet but with an adjustable arm for the camera this will be incredible! Thanks for sharing!!!
I had a similar idea independently a couple months ago. Absolutely awesome to see your execution. Definitely need to make my way through the rest of your library, loving it so far ;-)
Add a few stepper motors, remote shutter release, and a microcontroller and the whole process could be pretty well automated. I am so amazed/enthused about the advances in photogrammetry and desktop machining in the last 10-15 years. Wonderful times we live in.

Hey Luke,Eric is standing on your shoulders with this video. Nice of you to plant the seed in his head. All in all a nice collaboration, well done guys. 👍
A couple of weeks ago I made a turn table setup very similar to what you've made. It works well. I think these setups are a very good answer for small items.
angelo3d 1 segundo atrás Hello, sir. Here in Brazil everithing is very expensive. This solution you presented is 100% efficient. It owes nothing to commercial and so expensive devices. Thank you for sharing your knowledge.
Hi, Eric, I did one of this for my dental office projects. I put 4300k and 6k lights beside and above the center of that to improvel the lighting and put a green cardboard instead of white behind it. Nice job!
Denis Gerbassi de Oliveira I think lighting is key to making this all work. it could definitely work with green background as well, I can see it working as a green screen effect too.
Anton Konrad My boy is just starting out, so he is being ultra careful while the old man watches. Good for him, take his time and be safe! Glad you like the vid and commented, feel free to share on social media.
I actually made something similar to this for curing resin prints. I took a lazy Susan and put a circle of wood on it. Then I attached a synchronous motor out of a microwave to it to rotate slowly. Works pretty good for photogrammetry too
WOW I'm a newbie to this photogrammetry and having racking my brain on why my image of a white plastic 1/16 scale car body does not reproduce. I think I need to build me one of these tables verses trying to walk around it. What a great experiment that you did in making this. Thanks for the time and effort. Look forward to seeing more of your videos and will have to subscribe.
Great upgrade from the Ben Heck Element 13 build he did. Re-visiting this from when you first made and thinking I might do this in a maybe easier to disassemble design, albeit yours can be unscrewed as well with maybe some toothpicks or scrap wood if the woodscrew holes require. Thanks for sharing! Awesome design work!

I like turning the object it's self around, and keeping the camera stationary. I just use a lazy susan. Cool rig, these things can cost 500$ when manufactured so good on you for having the skills to make it your self.
Hi! Next step would be to add automation! Instead of rotating the whole rig, you could the middle using a dc motor and arduino! Attaching a light to the camera would also allow for a lighting constant! Love the video!
I built this rig only the model moves, I have three set positions on the camera support arc. Yes I choose ten degrees as well. Love the device , much better, easier. Great video,
Great one. I'm thinking of how to rotate camera around object and not vice versa right now. And found your video. All good, but I think this sheet on background rotating with rig may cause some problems 'cause lighting isn't consistent with it.
I'm researching how to make my own rig for the same, and maybe some photography. I've been thinking about using 2020 aluminum extrusions and adding one of the Nema 17 steppers that I have laying around the shop. I wanted to see if this was possible, and you just (5 years ago) confirmed it. Thank you.
Excellent video. I'm going to try the software out. So far my experience has been fair at best with other programs, but I'm sure my iPhone XR is the biggest issue. I'll report back.
🤔 The added back-drop would help to mitigate the noise induced to the images by stray reflection. Plus there would be a lot less to edit out from the scan. Nice build though 😊

Very nice. Thank you for the video. Have you ever made or know of any plans for a motorized, slow moving lazy susan that can support a human for 3d scanning?
Hey its a pretty cool project and I liked the way how you did it. I was wondeing if you have any problems scanning Objects which have a uneven bottom. Because your camera is only in one spot. I was thinking if you move the kamera from the top to the middle and then to the bottom, then you might get a better outcome. What do you think of that?
camera moves, three times actually, yes, you will have a problem on the bottom, you need to figure that out depending on the object and your priorities for your project.
Nice work. I had my design idea since two years. The arc which is carrying the camera is near quarter of a circle which goes from -15 degree to 80. But instead the rig is rotating around the subject . The subject sets over a turn table and turns around its axis which is much easier . And the subjects sets inside a lighting box which diffuses the light. Which is necessary for quality photogrammetry.k
I make a hires video while going around the object. Then extract frames from every 0.5 sec of my video then use those to make the photogrammetry. Works fast and great :)
@@EricStrebel I use a small free program to extract images from video. But the one i use now had a lot of spam and sale stuff in it and I reccomend you find your own.

@@MrMikedejeuner I'm not sure how you built your system, but I'm a software dev and I was doing an iPhone scan before Lidar and it was an older phone. It needed feedback for all the things it got and took a while to get the details. One of the key things is that it has to be able to know what side it's currently doing, in order to put things in order. Kinda like a single die, you have sides that are all different because they have a different number of dots on them. I've never built my own scanning system, but I'd guess it would need to be a slow turn and hitting different angles would probably help too. I think it's the background that matters. Maybe the phone knows more about where it is when you move it.
HI Eric, I'm not sure if someone already ask you the same question. If you make the object and lighting turn together instead of the camera and the background, will there be a difference?
@@EricStrebel I actually already started the drawings and plans you really inspired me. I'm doing it a little different tho, thinking about using a bike wheel fixed on a metal surface as a base. I dont have much tools so that might be easier for me
@@EricStrebel also what would you recommend to create a dimmed uniform light in a room so the lighting doesnt create any not wanted shadows, for best results
This is great! Glad I have seen this. Now you can make free high res 3D scans for almost free instead of buying an expensive 3D scanner. This result is the same as an expensive 3D scanner of 3000 dollar or more. One question. Do you think it is possible to scan larger objects of about 1 meter, or 1.5 m ?
What I found to work best for me is to rotate the object itself, the final texture comes out uniformly lit on the entire surface, this way the object can be accurately lit in the 3d engine. Just a simple turntable used by cake shops, and the camera set on a tripod at different heights
@Song Zee: Your result is impressive. Did you motorize the turntable, or manually spin it in increments? Any photos or footage of how your process goes? Also, I'm curious why you mentioned you had to do different heights with the camera+tripod...
I have the same idea, why rotate camera, it’s easier to rotate object itself. If the lighting is ambient and close to constant the result should be fine…
What if you add a chessboard background instead of a white one, so the machine can compare it and make some calculations? Does the software allows you to manually or through script, telling what is the position/angle of the picture? So if you are using a stepmotor, you can tell the software exactly how many degrees you turn in each picture. What about placing some line lasers and taking the pictures in a isometric view, so you can calculate the distance from the red curvy line projected on the surface to the turning axis (like in a solid of revolution, where you have the line of each degree that will spin).?
Rodrigo Jäger I have no idea, reach out to the software manufacturer, as far as I can tell it figures all that out by itself, watch my most recent scanning video here for more insight. ruclips.net/video/b1t33KcBlnk/видео.html
As far as I am aware, it uses artificial intelligence comparing features from the 3D object and from the background to process how one picture connects to the other. That is why I believe having some sort of background, but still easy to differentiate from the object itself would help. Your result is amazing already, I was just wondering if you can combine this technology with others like counting known steps or tracing projected laser lines to pixels in some sort of triangulation and high order linear regression would improve the results for more situations. We know for instance that if the reflection of the light is not perfect due to refractions in materials like glasses or reflections in shinning objects, it would not be that good. So maybe it is possible to improve it with low cost technology and getting a quality better than some high cost solutions...

Love this video! Would you be willing to share your dataset? I'd love to prove out the software tool chain before making the effort to build the gantry
Excellent! I thought it would not work without tracking pattern between turntable and item to scan. Maybe the rough plywood provided enough of a pattern to track.
When I played around with this photogrammetry stuff several years ago I found benefit from placing coloured tracking dots on the surface the object was sitting on.
Wow that's quite impressive! I'm working on an auto shoot that rotates the object with a stationary camera but I doubt I will get results anywhere this good :/
hi, l really good watching your video. and I have a question. May I know the name of the tool that supports the camera? For example camera rails. l really wait ur answer
@@EricStrebel ok thanks for the reply. Did you try your setup but witout the background? If so it would be interesting if the result is better but i guess if you build this kind of kamera rig attaching a plain baclground to the other side is the least amount of work...
Greetings Eric. So glad I found this video and the way of using lazy Susan. I do have some questions though, and if it's possible some kind of modifications to this model. The issue with my model is that, well, it's a full size mannequin with old ethnological outfit. I need to create a small printed 3D model from the mannequin, something like palm-sized model, using of course the method of photogrammetry. I was thinking of placing my DSLR on a tripod and use additional studio lights which are controlled by a trigger from the DSLR. Then, placing the mannequin over a lazy Susan base (made from something more sturdy than a plywood, probably steel lazy Susan), and using the same technique like you - rotating every 10 degrees for a full circle. The background is going to be white canvas (used for photoshoots of real models) made as infinity wall (without a corner behind the mannequin) My dilemma - is this way of rotating is efficient and reliable? I'm going to use the same light and photo settings, and there aren't any glossy or transparent surfaces. Thank you.
Yes, the subject on a lazy susan will work too. Make sure to take 36 shots each from ~10’ high, mid height and low height, trying not to change the distance from the subject.
Eric, did you use the standard version of the software or the professional? And did you check to see how well it captured the true size of the object it scanned (the standard version you have to manually play with scaling to get it close).
At first I thought it might be possible, but I don't think so. Say you used the same object Eric did, I think in your version the end result would be a model that was cylindrical with the features of widest edges.
What can save a lot of time and can take up to 11,000 pictures per rotation is a computer-controlled photography turntable. Iconasys makes 6 different sized turntables (1.5lbs-500lbs.). Set however many images and angles you want. Automatically removes the background on each image too. www.iconasys.com
so my spin of your wonderful ideas is the following ........ DSLR camera that is remotely triggered. Camera is attached to a fixed robot arm that moves to appropriate angles . Object rotates on turntable controlled by stepper motor. Diffused LED lighting rotates with the object. System is shielded from stray light ( darkroom ? )
Given a choice I always turned the subject rather than circle it with the camera. I think it is easier to maintain uniform lighting and a great deal faster as there is less time between images.
Idea was good! But maybe it was easier to put a rotating table and fix the camera so the object is just there, at the same height within 0.5 mm difference. With that long arm holding the camera, there's a momentum that moves a little up and a little down the camera. Another tip, you could use a remote app to shoot photos avoiding any micro-movements. And... last but not least, adding a flat egg timer under the table, could automate the rotation so the only action would be press the "Shoot" button on the smartphone :))) Btw nice video!
@@EricStrebel You are wrong. This software is working with a rotating table. I've built more than 1.5 year ago a fully automated turntable rig with rotating table. Since then I have no problems with the results. And the key is in proper light setup. Rig with rotating table has more pluses as for me. Occupy less space, more stable when camera moving upward (my do it automaticly) as I have more pionts to fix the arc.
@@КристинаТихончук-л4ъ perhaps, good for you, I am just not able to create a diffused light source, that will create a uniform lighting, so I will have to stick with my solution, feel free to share your creation on social media with me, I would like to see your set up @ botzendesign

@Eric Strebel Great video. Very informative. Thanks you for sharing it. Do you think the camera could be mounted onto the Lazy Susan and pointed outwards so as to take photos of a small room? I'm wondering if Photogrammetry could be used instead of Lidar scanning?

Super cool design! I like the way you lay things out "simplistically" and build up! I might steal parts of the idea as I am messing around with Meshroom (github.com/alicevision/meshroom/releases/tag/v2018.1.0) and it likes the object to remain stationary rather then sit on a turn table itself.
wouldn't it have been easier to just rotate the bottle instead. you could even have used a motor to turn it slowly. The light would stay constant and so would the background...?
Rich Sobocinski most os the software does not work that way, unfortunately. It wants the camera to move and the object and lighting to remain constant. Thanks for your comment.
@@EricStrebel would a black background provide more consistent lighting? the white does a lot of reflecting. not that it didnt work great but an easy enough upgrade.
Scott Tuttle good question! You are definitly right about the bounced light. I would think that there needs to be enough contrast between the object and the background and then that could work. Dunno, might have to try some day. Thanks for the suggestion.
Rich Sobocinski Don't worry you are not alone, lots of head scratching going on with this photogrammetry software and process. But the other way just does not work so great when the object moves unless the lighting is super constant. The software seems to play a big part in the equation as well, basically I am tricking or hacking the software on a physical level.
WOW! this is the first time I've seen a hobby photogrammetry rig actually produce good results. I am so building this and buying metashape.

Wonderful try!! Do you need to masking each of the photos before alignment, or you direct align those photos. Thank you!
I don't have to do anything the software takes care of it no post-processing of the photos required on my end
@@EricStrebel how do you remove the whiteboard background on Photoscan? change the bounding box or?
the software does some how.
it works !!!
What I found to work best for me is to rotate the object itself, the final texture comes out uniformly lit on the entire surface, this way the object can be accurately lit in the 3d engine. Just a simple turntable used by cake shops, and the camera set on a tripod at different heights
What software supports that? Most do not....
@@EricStrebel I used RealityCapture ruclips.net/video/d3DA2jB2nQE/видео.html
@Song Zee: Your result is impressive. Did you motorize the turntable, or manually spin it in increments? Any photos or footage of how your process goes? Also, I'm curious why you mentioned you had to do different heights with the camera+tripod...
I have the same idea, why rotate camera, it’s easier to rotate object itself. If the lighting is ambient and close to constant the result should be fine…
The software does not work that way
What if you add a chessboard background instead of a white one, so the machine can compare it and make some calculations? Does the software allows you to manually or through script, telling what is the position/angle of the picture? So if you are using a stepmotor, you can tell the software exactly how many degrees you turn in each picture. What about placing some line lasers and taking the pictures in a isometric view, so you can calculate the distance from the red curvy line projected on the surface to the turning axis (like in a solid of revolution, where you have the line of each degree that will spin).?
Rodrigo Jäger I have no idea, reach out to the software manufacturer, as far as I can tell it figures all that out by itself, watch my most recent scanning video here for more insight. ruclips.net/video/b1t33KcBlnk/видео.html
As far as I am aware, it uses artificial intelligence comparing features from the 3D object and from the background to process how one picture connects to the other. That is why I believe having some sort of background, but still easy to differentiate from the object itself would help. Your result is amazing already, I was just wondering if you can combine this technology with others like counting known steps or tracing projected laser lines to pixels in some sort of triangulation and high order linear regression would improve the results for more situations. We know for instance that if the reflection of the light is not perfect due to refractions in materials like glasses or reflections in shinning objects, it would not be that good. So maybe it is possible to improve it with low cost technology and getting a quality better than some high cost solutions...
Have you built a final version using good materials as you mentioned or does this proof serve you well?
Nope have not built anything beyond what you see in the video this is working pretty good
What can save a lot of time and can take up to 11,000 pictures per rotation is a computer-controlled photography turntable. Iconasys makes 6 different sized turntables (1.5lbs-500lbs.). Set however many images and angles you want. Automatically removes the background on each image too. www.iconasys.com
When you use backboard it will reflect light onto the object which will make the lighting change as you rotate
Hmmm, perhaps but not enough to disport the scan of the object it appears, so should be good
Fantastic idea!
Thanks!
Love this video!
Would you be willing to share your dataset?
I'd love to prove out the software tool chain before making the effort to build the gantry
Well, I don’t have the data set anymore to share it’s rather large anyway it would be difficult
Excellent! I thought it would not work without tracking pattern between turntable and item to scan. Maybe the rough plywood provided enough of a pattern to track.
error079 Yeah, I was pretty surprised as well, I will reach out to Agisoft and see what they say and get their thoughts as well.
When I played around with this photogrammetry stuff several years ago I found benefit from placing coloured tracking dots on the surface the object was sitting on.
@@lukefrahn8538
There’s also photogrammetry spray you can use. It’s expensive though.
Wow that's quite impressive!
I'm working on an auto shoot that rotates the object with a stationary camera but I doubt I will get results anywhere this good :/
hi, l really good watching your video.
and I have a question.
May I know the name of the tool that supports the camera? For example camera rails.
l really wait ur answer
Turntable
Great one man.
OMG, imagine if WarCraft had it this way for modding and skinning!!
Is lighting that important? would it be helpful to have top lighting to simulate mid day to avoid shadows
Yes apparently light is important in photography and it needs to be has diffused as possible with the setup.
what would be the difference if I rotate the object instead of the camera?
Probably will not work with this software
@@EricStrebel ok thanks for the reply. Did you try your setup but witout the background? If so it would be interesting if the result is better but i guess if you build this kind of kamera rig attaching a plain baclground to the other side is the least amount of work...
Greetings Eric. So glad I found this video and the way of using lazy Susan. I do have some questions though, and if it's possible some kind of modifications to this model. The issue with my model is that, well, it's a full size mannequin with old ethnological outfit. I need to create a small printed 3D model from the mannequin, something like palm-sized model, using of course the method of photogrammetry.
I was thinking of placing my DSLR on a tripod and use additional studio lights which are controlled by a trigger from the DSLR. Then, placing the mannequin over a lazy Susan base (made from something more sturdy than a plywood, probably steel lazy Susan), and using the same technique like you - rotating every 10 degrees for a full circle. The background is going to be white canvas (used for photoshoots of real models) made as infinity wall (without a corner behind the mannequin)
My dilemma - is this way of rotating is efficient and reliable? I'm going to use the same light and photo settings, and there aren't any glossy or transparent surfaces. Thank you.
Yes, the subject on a lazy susan will work too. Make sure to take 36 shots each from ~10’ high, mid height and low height, trying not to change the distance from the subject.
Eric, did you use the standard version of the software or the professional?
And did you check to see how well it captured the true size of the object it scanned (the standard version you have to manually play with scaling to get it close).
I have a licensed copy of the software, scale is not relevant for me, have no idea what scale it is is once it's done, I just scale it to what I need.
This was really cool, thanks! have you taken it further?
very good !
2:56 Be careful of Hair getting caught up in blades, etc...
Seen this happen to someone using a drill, not very nice
The minute I saw that I thought "that's a scalping".
Tie that hair back if you wanna keep it!
@MetalArtDesign Schreilechner q
Would rotating the object instead of the camera work if my lighting is diffuse and I put distinguishing marks on the rotating base?
Try and see if it works, possibly it might
At first I thought it might be possible, but I don't think so.
Say you used the same object Eric did, I think in your version the end result would be a model that was cylindrical with the features of widest edges.
What can save a lot of time and can take up to 11,000 pictures per rotation is a computer-controlled photography turntable. Iconasys makes 6 different sized turntables (1.5lbs-500lbs.). Set however many images and angles you want. Automatically removes the background on each image too. www.iconasys.com
so my spin of your wonderful ideas is the following ........ DSLR camera that is remotely triggered. Camera is attached to a fixed robot arm that moves to appropriate angles . Object rotates on turntable controlled by stepper motor. Diffused LED lighting rotates with the object. System is shielded from stray light ( darkroom ? )
I like your spin, but who's going to design and build all that extra stuff it's just not worth it for me for occasional use.
Eric Strebel .......i can definitely see your point
Given a choice I always turned the subject rather than circle it with the camera. I think it is easier to maintain uniform lighting and a great deal faster as there is less time between images.
This software works best with this set up
Idea was good! But maybe it was easier to put a rotating table and fix the camera so the object is just there, at the same height within 0.5 mm difference.
With that long arm holding the camera, there's a momentum that moves a little up and a little down the camera.
Another tip, you could use a remote app to shoot photos avoiding any micro-movements.
And... last but not least, adding a flat egg timer under the table, could automate the rotation so the only action would be press the "Shoot" button on the smartphone :)))
Btw nice video!
This software will not work with a rotating table, lighting needs to be consistent through the entire shoot. Thanks for the comment and support
@@EricStrebel Oh ye, you are right, I skipped just those seconds where you mentioned it! Sorry...
@@EricStrebel You are wrong. This software is working with a rotating table. I've built more than 1.5 year ago a fully automated turntable rig with rotating table. Since then I have no problems with the results. And the key is in proper light setup. Rig with rotating table has more pluses as for me. Occupy less space, more stable when camera moving upward (my do it automaticly) as I have more pionts to fix the arc.
@@КристинаТихончук-л4ъ perhaps, good for you, I am just not able to create a diffused light source, that will create a uniform lighting, so I will have to stick with my solution, feel free to share your creation on social media with me, I would like to see your set up @ botzendesign
Where did you get and what is the name of the paint that is applied over the plastic bottle for making fine details?
It’s just regular automotive Sandable gray and white and black primer, duplicolor brand
@@EricStrebel Ah, so it is important that second, dark coat actually 'spitting' big droplets instead fine ones?
I feel some contrast is helpful
@@EricStrebel It is very helpful. Tried to make 3D model of the car - epic fail: no roof, no windows, everything else distorted (except 10% of the side parts). I can't paint my car, but for everything else.... Thanks.
What degree arch did you use for this? Perhaps some measurements or a drawing of the design so others can try it?
it's going to be based on the camera and the lens that you have and the objects that you're trying to scan everybody will need something different
Is it working with more complex objects? I would like to 3d print something similar
Yeah, it should work
Great Job! Any link to finding the template so I can try this myself pls? Thanks! :-D
One other question. How did you determine the camera length?
wouldn't it be easier to rotate the object on the lazy susan rather than the whole camera mount?
Yes, of course it would be, but not with this software.
@Eric Strebel Great video. Very informative. Thanks you for sharing it.
Do you think the camera could be mounted onto the Lazy Susan and pointed outwards so as to take photos of a small room? I'm wondering if Photogrammetry could be used instead of Lidar scanning?
Possibly, try it out see if it works
nice
could you have the turntable that the object is sitting on rotate and the camera stay still?
Not with this software
What can save a lot of time and can take up to 11,000 pictures per rotation is a computer-controlled photography turntable. Iconasys makes 6 different sized turntables (1.5lbs-500lbs.). Set however many images and angles you want. Automatically removes the background on each image too. www.iconasys.com
You can use a inexpensive stepper motor to turn the lazy susan accurately
Yup, that would be great
nice ! exif of camera shot ?
I don't understand what you're asking me
@@EricStrebel hi Eric .. Camera settings, aperture, shutter speed, focal length for example
The important thing is to get a large depth of field so everything is in focus. The rest does not seem important, other than soft lighting.
Why not keep the camera and background stationary and have the object on a slow turntable?
Yooo what programs did you use ???
Which softwere use after scanning to mesh
Super cool design! I like the way you lay things out "simplistically" and build up! I might steal parts of the idea as I am messing around with Meshroom (github.com/alicevision/meshroom/releases/tag/v2018.1.0) and it likes the object to remain stationary rather then sit on a turn table itself.
DIY3DTECH.com use what you need. Good luck!
Add a random pattern to your rotating base for better detail and tracking
Good idea
@@EricStrebel yours has one with the wood grain I think that's why it tracked so well
wouldn't it have been easier to just rotate the bottle instead. you could even have used a motor to turn it slowly. The light would stay constant and so would the background...?
sure would, but this software does not make that easy.
Where can I buy it already?
Why wouldn't you just rotate the object in the center and keep the camera, background, and lighting stationary?
Rich Sobocinski most os the software does not work that way, unfortunately. It wants the camera to move and the object and lighting to remain constant. Thanks for your comment.
@@EricStrebel would a black background provide more consistent lighting? the white does a lot of reflecting. not that it didnt work great but an easy enough upgrade.
@@EricStrebel sorry, still scratching my head. I don't see how the s\w knows the difference. It's still getting 360 degree image data
Scott Tuttle good question! You are definitly right about the bounced light. I would think that there needs to be enough contrast between the object and the background and then that could work. Dunno, might have to try some day. Thanks for the suggestion.
Rich Sobocinski Don't worry you are not alone, lots of head scratching going on with this photogrammetry software and process. But the other way just does not work so great when the object moves unless the lighting is super constant. The software seems to play a big part in the equation as well, basically I am tricking or hacking the software on a physical level.
