3D Scan a Building with Reality Capture
HTML-код
- Опубликовано: 4 окт 2024
- Using Photogrammetry with Reality Capture I'll show you how to scan a full size building (or most of it). We'll take a look at some problems you might face and how to resolve them as well as how your scan looks in a couple of other 3D programs. The cameras I shot with are a Galaxy Note 8 phone and the DJI Phantom 3 Standard.

By far, the coolest thing I've seen all year.
This is literally one of the coolest things I have ever seen, I just got microsoft flight simulator 2020, noticed Castello di Vigoleno in Italy did not have photogrammetry data, and now I can add this in. I can even 3d print a little model, this is so, so cool. It will cost like 10 dollars to export, but it will be well worth it.
Great! If you can get the pictures you can do it!
You can upload your own photogrammetry to flight sim? That's awesome I didn't know that
Man you are the best i watched your last vidéo on photogrammetry, invested 2k in the same setup and 2 printers, and it works perfectly for my project.
Thanks man !
Keep detailing all small things please ! It helps me
Thanks a lot! You know it's funny, the people from Mocha asked that I make my next tutorial shorter but I thought, "I think my viewers would rather have all the details...".
Really insightful and straightforward video, thank you.
Glad you liked it!
BTW what do you think of my new intro? I tried to keep it short to not be too distracting.
Lightwave 3D, so nice to see it being used!!! the scanning part is epic too
Been using LightWave for about 20 years. Do all my modeling and animation work with it.
So, let's grab this blue dot - DOT is actually yellow xD
Just kiddin', very good video mate, helping me a LOT right now with my Bachelor;)
The dots turn yellow when you mouse over them. Until then they're either blue, red (pink really), or green.
Great video looks amazing!
Thank you!
What would you do with a scanned building? Make a game environment? Use it for set extensions?
BTW the idea I was talking about for the lighting at 0:59 was a tool in Unity called Delighting, which supposedly removes all shadows from a texture. Although in my tests it didn't work very well. If I get it working I'll make a video.
That's fantastic. Could that work with 360 photos?
Edit: wait, what if you could use 360 video? With a Samsung Gear 360, at 30fps, that's 30 4k pictures a second. If you could lower the poly resolution to help performance, one pass with a drone and you have a whole street. Come back the same way at a different height, you just doubled your quality.
@@GiffysChannel sorry I missed this, no it will not work with 360 photos. You need pictures that overlap and the whole point of a 360 photo is no overlaps.
@@3DJapanhmmm, I see what you mean. Thanks for getting back to me anyway lol. It sounds like it would be possible to do but just not in this software. I'm sure there would be a way using a non-euclidean type algorithm but ya, that pretty much beats the purpose of the simplicity of doing this way.
even Blender has crashed? Did you try Blender?
Very informative
Nice job and video.
Thanks!
Great tutorial!!
Thank you!
nice work
Thanks!
Great Video Phil. This is really so educative. I am a graduate Architect and am currently trying to beef up my visualizations for my projects...tryna make them look real, and such kinds of videos are my go to, for days. Would you consider making another video illustrating on how to do further clean up of the model before exporting to a photo rendering software
Thanks. I have thought about making one on cleaning up scans. I usually do it in 3D sculpting software like 3D-Coat. At the moment I'm working on a paid tutorial on architecture but maybe that will be next.
@@3DJapan if you are well versed with 3ds max, then maybe if you would consider trying it out with Max, it would be a completely great pleasure. thanks for the reply btw
@@ianmukiibi3 Sorry I don't know max. I tried to learn it a couple times but it was so cumbersome I gave up every time. I do all my modeling in LightWave 3D.
Phil, thank you for such an informative video. Is RealityCapture good for doing indoor scans or inside vehicles?
I only briefly tried my living room but it worked fine. Inside a car should be fine too.
if i got a 3d model of a building and want to sent it trough e mail how can the other person view the model if they don't have reality capture installed?
Sorry for the late reply. The model will likely be in OBJ, PLY, or STL format. Just about any 3D program can view those, even Windows 3D Builder.
ok gooood
Cool !
You ran into memory limitation several times. What are the memory specifications for 1) the computer and 2) your graphics card?
I have 16 GB PC ram and 6GB video ram. I think the total number of polys before simplifying is about 54 million.
@@3DJapan which gpu do you have ?
@@redskull5482 nVidia GeForce GTX 1060 with 6GB ram.
Amazing video! :D
Thanks!
Hi I am working in camera track dipartment your video realy help me to understand lidar scan I just want know that, is that mesh has a proper scale like that real world? Sorry for my bad English but I hope you understand what I am trying to ask you please reply ASAP Thnks. 😊
I don't think it's correct by default. I measured one of the doors on this model and it was 4.4 meters (14.4 feet) tall. Which seems about double what it should be. I think Reality Capture has some measuring tools but I haven't looked at them.
caraca ate isso pede gpu mas esses resultados sao impressionantes ainda pretendo fazer uma cidade com esse softer maravilhoso imagino o trabalho da pra fazer 12:56
Também imaginei isso. Moro numa cidade muito pequena. Acho que consigo fazer com um drone.
Great video. Im super interested in this as Im trying to get a 3d model of the exterior of my house so i can view / edit it in sketchup. Is that possible with your programmetry technique of using video, multiple pictures and reality capture?
Why thank you. I don't see why it wouldn't be possible. If I can do I building this big you can certainly do your house.
@@3DJapan Awesome and thanks so much. I'm super new at this and my last attempt didnt go well. Is this a tutorial for a newbi that youd recommend? If not, is there a tutorial that do recommend for a beginner?
Can you do inside rooms, for dollhouse effect?
Yes as long as there's enough detail. Printed wallpaper would be very helpful.
Can you measure size of Windows from this model? Actual size... or do you need a cherboard placed in the view To scale to correct size?
Me and some colleaugues are starting the 3d scanning of a looot of the Italian heritage (like statues and so on) to make disponible 3d models identical to the original for games movies an so on, do you think that somebody will be interested? thumbs up if you think so!
Interested in buying them? Probably, if they're making a historical game like Assassin's Creed.
Hey Nice video,
Any idea how to 3D photoscan without a drone?(Would clicking pictures from other rooftops work?)
Please advice if there any other alternatives for 3D scanning without drone :)
For a whole building without a drone I guess you could try other rooftops but it might be a challenge to get on top of all the roofs surrounding the main building. Just remember standing in one place and rotating your body like a tripod won't work. You have to physically move the camera to the side or up and down.
You can share all pictures used on this project?
Thanks 🙏🏼 for your great tutorial
Kindly please do tutorial for Scanning real people to 3d model
I have done one with a 3D scanner but not with Reality Capture. It's really the same process as scanning objects though, just make sure the person stays still and be sure to get all the angles. Under the chin, under arms, to of the head, etc.
Phil Nolan okay thanks bro , If you can do the tutorial in Reality capture I will be very happy to see the shooting and the process
@@redmagic_io Well I've never actually done it so I'd have to get my friend to agree to it again. Unless I can think of someone else.
Is it proportionately accurate? If its in autocad will it match up to its true scale? Thanks
proportionally it should be accurate. Scale wise I'm not so sure. I measured a door on this building and it was 14.5' x 7.5'.seems a little large. Haha
Phil, may i know how much money to pay to export this whole model from RC?
I don't remember off hand but under a dollar (USD) I think. Maybe around 80 cents?
If you didn't have the drone for the aerial shots - would images from google maps work??
Google maps images are really low quality so you might get something but probably not anything good. Unless you mean the satellite made for the maps. In that case I don't think it would work at all. I don't think they have any parallax difference. The perspective stays the same in all of them.
Hello! Please, should i always use wide angle lens? Around 23 mm, for example, or always the closest to human "view", 50 mm?
I would not use a wide angle, it distorts the image. You want as little distortion as possible, so yes I would go with 50mm.
I looked at the software price and it seems to be $300 a month. Is there any cheaper alternatives?
You can pay per use. You add a certain amount to your account ($20 or whatever) then the software takes from that when you export the model. Which is great because you can scan as much as you like for free, trying stuff out, and only play when you export. The fee is based on the number of megapixels used. My last scan cost like $1.30 I think.
what drone and camera it looks like fun
It's in the description. Camera was my Note 8 phone. The drone is the DJI Phantom 3 Standard.
Guys pls help how to get RealityScan invitation Code?
I don't use apple products so I would have no idea.
What drone u using ?
This one was the DJI Phantom 3, though any done with a decent camera would work. These days I use the DJI Mavic Mini.
is this better then meshroom?
Way better in my opinion. Easier to use in some ways and higher quality result. Much nicer interface too.
Are you Gothic King Cobra's brother?
Hi Phil,
Is this better to use than Agisoft Photoscan?
I have only used Photoscan once a long time ago. I think this is much more user friendly though from what if seen they give similar results.
Hey man! Do you know if this is compatible with autocad? Could I import this to an autocad environment or a DWG file?
It only experts OBJ files so if your software can load those it will work.
hello can I ask? is there any software where can I edit two 3d object and connect them together.
Plenty will do that. I believe Mesh Mixer is free.
@@3DJapan ooh thanks ^^
@@3DJapan hello phil last question how can I output the 3d to the browser or in html form? aside from using X3DOM
@@ruelcapistranojr.1328 Sorry I don't know what x3dom is. Never heard of outputting 3D to a browser. You can upload the model to Sketch fab to display it, like RUclips for 3D models, but I suspect that's not what you mean.
@@3DJapan ooh okay thank you for entertaining my question :)
trash looks real
Hopefully they've cleaned it up by now, I've haven't been there in a while.
@@3DJapan 😅😅
Not worth the burden. They have to invent something more accurate.
There are more accurate scanners, down to a fraction of a millimeter. I even have videos on one. But they cost way more than this does. This also has the convenience of using just a regular camera.
Photogrammetry can be more accurate if you do it better :) I saw he used just a phone camera... forget about it if you are serious with photogrammetry models and use proper camera, ideally full frame with 20 mpix or something. Also use tripod for sharp photos, take many photos, hundreds of photos for building like this if you want all the details like staircase going to the basement etc . And the same applies to your drone - decent camera, many photos. Then your results will be completely different.
Regarding lasers - yes there are lasers accurate to fractions of mm but these are used for close range scanning like reverse engineering of some mechanical parts etc. Typical terestrial laser scanner you will put on tripod and scan building like this will be accurate around 5 mm up to 50 m distance lets say. If you are keen to invest 200 000 euros for some top quality scanner then you will be able to keep that 5 mm accuracy to much longer distances.
would this work just using google maps being in street view?
Google maps doesn't give nearly enough photos.
nice work
Thanks!
