This is probably an insanely hard question. So far ARKit works with 3D models which are built in 3d modelling software. I was wondering if there was a way to use iPhone camera to scan 3d object (let's say a car), then use it in ARKit.

Any open source projects available which do this on other platforms or iOS?

You are looking for software in the "photogrammetry" category. There are various software tools that will stitch your photos into 3D models, but one option is Autodesk Remake. There is a free version.

  • I know this is a very hard question but if I were to code my own way of creating such 3D models from pictures, how should I approach it? Reason being i need to be able to do this on an iOS device. Do you have any pointers or am I asking TOO BIG of a question? – sudoExclaimationExclaimation Aug 29 '17 at 19:56
  • You should probably not create your own. Look at partnering with the makers of the Trnio app. – Marcus Adams Aug 29 '17 at 20:10

ARKit/RealityKit on iPad/iPhone with a LiDAR scanner let you reconstruct a current scene and obtain a 3D geometry with an Occlusion Material applied. This geometry allows you occlude any object including a human being and physically "interact" with this generated mesh. LiDAR's working distance is up to 5 meters.

However, scanning a car isn't a good idea due to paint's high reflectivity.

    I was trying this out. In my use-case, I need a more accurate detection and measurement of humans bodies near camera. I was thinking of creating a new configuration for my case, but seemingly got lost. Is there any better way to do it? Am I missing something? – Abhishek Kumar Feb 03 '22 at 11:23
  • Hi @AbhishekKumar, The best solution would be to create a question with all the details and cases – what worked and what did not work. – Andy Jazz Feb 03 '22 at 14:41
