A fully printed camera rig to use for photogrammetry. There are some scan examples at the end of the video. Check out my other videos for more scans and another scanner principle.
You can download the 3d printable files from thingiverse: www.thingivers...
See my profile there to find more 3d scanned models

That scanner is great. it even captured the shoemaking elf who lived inside the boot.
Yessss i knew someone made the perfect solution
Looks wobbly
It is ^^ but this only served as a proof of concept
This is badass, great work!
Impressive rig dude.
Great little setup. Any progress on the documentation?
Is the shadow really okay? I noticed Photoscan has probs with shadows (even if the shadows are way in the back of a model)
very cool. ty for your work.
I had come up with a similar concept, but I see no reason for a full 360 degree ring when you only need half.
Sure, half a ring would be enough, but I have no idea on how to make it stable enough to carry a DSLR. Even the full ring is quite wobbly...
Well I was looking at the idea of a semi-circular steel bracket with side supports and using a nylon gear track.
Yours is the closest I have seen to my concept.
I would also build a truck with bearings for the camera mount.
I plan on using a DSLR and lights (either LED or flash), so the whole rig would have to be fairly sturdy because of the weight.
I was also considering incorporating a cable guide with a pulley at the end of the arm and a weight to act as a counterbalance so as not to overstress the motor.
What's the lighting/shadow like with your ringlight?
@@TryptychUK hei did you try your idea? is it work?
@@nurulistibudi9367 Sort of. Still a work in progress. The concept works but it needs to be simplified and refined.
@@TryptychUK do you intend to share your work? If yes, where i can reach you?
Why does this work? Normally, having the light source moving with the camera confuses the algorithm, you have to have steady light. So how does this work?
The problem with moving light sources is, that they result in moving shadows, which will indeed confuse the algorithm. In the video, the ringlight produces a shadow-free illumination (from the cameras perspective), so you do not run into the mentioned issue
Wow Incredible!
can you write some documentation on how to assemble this properly? thanks!
As this was just a very wobbly prototype, there is no explicit documentation. The wiring and programming stuff can be found here: openscan-org.github.io/OpenScan-Doc/, but the assembly of the printed parts definitely needs some tinkering. to be honest, the whole design would need a remake, as it has several technical flaws, which have been solved through the different models (see openscan classic/mini)
How did you make the holder for camera?
This is just a 3d printed part with a standard 1/4'' screw inserted
I'm enjoying the video
but i have a question
By any chance, why didn't you fix the rail and move the camera?
I wonder why the rails and the camera are attached
You are absolutely right! Just at this point in the past, I have not been very experienced and this seemed to be the logical and simplest solution ;)
I thought that in order to work properly photogrammetry required the lighting on the object to be constant, or better, constant light source position relative to the object. Here you change the lighting at every repositioning because the light moves with the camera. Am I wrong?
Hey, you are partly right ;) Generally speaking the lighting conditions should be kept constant, as you do not want any moving shadows. But using a ringlight does not produce any shadows (from the camera's perspective), so this way the camera can and the lighting can move
That is bad ass!
Should it not be a moving cam and still object kind of setup ?
This is a common misconception. As long as the object has significantly more features then the background, the software will "see" a relative movement between the camera and the object. :)
Can I ask why you chose to move the camera rather than the subject instead with this rig? I noticed on your other rig you rotated the subject while the camera remained still and wondering if there's a benefit to doing it this way instead.
This one was just a try. Acctually there are some objects, that can not be tilted, as they would change their shape. Eg shoes (shoelace would move) or instable objects. But for my purpose, the other scanner is way more reliable then this quite unstable wheel
I thought you weren't suppose to rotate your subject matter?
So I guess that means I can turn the subject or object that I want to 3d model, have you had any loss of detail or noise in your scan? I had heard that it was an issue.
It is possible to rotate the object as long as the background is uniform and/or you use masking in the software. Than there shouldnt be any problem or loss of detail. See this picture set&scan example of mine: instagram.com/p/BtqG4NToIMQ/
Did you synchronise the shoe rotation with camera shots?
Yes, it is all synchronised via the arduino, which controls both the motors and the shutter release. Lately, I've also developed a script to run everything from a raspberry pi :)
@@openscan_eu Your work is really well done, you've been inexorable to me. I am approaching 3D printing (many tell me that given the age it is better to let go, but I do not listen to them); I'd like to be able to print out what you did. I end the speech by thanking you for your response and I hope to be able to achieve something like this. Hello from Parma
@@raflonoce Thank you so much, this is really kind! There is one more thing I want to add. I got into 3d printing in 2017 without any prior experience, neither in CAD/engineering/soldering/programming/scanning ... When looking back, 3d printing has been the gateway for a whole new set of amazing tools and by now I use it on a daily basis for a lot of prototyping and printing small household items.. This journey of learning has been challenging but amazing! And it will go on, as there is a lot more to try out :) And as the entry level to 3d printing got really low-cost (e.g. Ender 3), it is quite easy to get into it... :)
Great idea, but the system is very wobbly.
You are absolutely right, this setup was just one try and I discontinued its developement as the other scanner setup is way more reliable
@@openscan_eu what "the other scanner setup"....?
@@nicolausadinugroho1133 This one here: www.thingiverse.com/thing:3050437 (also published in detail on www.openscan.eu/?lang=en)
Great set up. Which software do you use to put the images together and create the geometry?
Thx! I started by using OpenMVG or Agisoft Photoscan, but since a couple of month I am using VisualSFM only (+Cloudcompare for the Mesh)
MR. WALT DISNEY WILL NOT LIKE THIS INVENT
Might be that times have changed and some business models might have to adapt as well... ;)
your thingiverse page only has parts for print, nothing on how to build it or wire/control the rig
you are absolutely right. I am currently rebuilding the circuit and i am working on the documentation of the project, which i am going to release in the next few weeks
Any updates?
3D TM Any updates on the documentation? This looks like exactly what I need to build!
Yup, would be very interested in building this too!
@@openscan_eu Gibt es schon ein Update?
I wish I could design this for human head scanning :)
This would be a possible application and I might try it next year (as my to-do-list is quite long at the moment ;)
@@openscan_eu Because I'm trying to design a special mask for my face and having a 3d scan would be IDEAL. It would be like your design but horizontal... and slightly larger to accommodate the head
When you need it only once, why not do it manually? (e.g. sit on a chair and a second person takes the photos). I ve tried this with my iphone and the result was quite good
@@openscan_eu unfortunately I don't have a second person
When you just need your face and not the back of your head, you can do it with your smartphone and a couple of selfies. Only challange is not to move while taking the photos
this is insane, start trk was doing this stuff with replicators, now anyone can own a 3d printer, u do have a microwave zz/..
