Record3D app #75

"If you want to use your own camera poses, you will have to process them our NSVF-based format, which is fairly simple anyway (see below). Other than proc_colmap there is also proc_record3d.py which processes captures from the iPhone app Record3D to our format; this might be a helpful example."

Can you expand on which settings are needed for recording and exporting with the Record3D app? It appears that proc_record3d.py is looking for an mp4 file.

Update: I've purchased the app and tried exporting the mp4 and found the metadata.json file. However, the poses are all zero. Any ideas?

Hello, unfortunately I actually don't own a LIDAR iPhone myself, so previously I only worked off some data provided by a labmate. I will try to improve the Record3D support soon.

Unsure why the poses would be all zero in the original metadata. Might be an ARKit issue?
