Format of camera poses listed in frame_annotations.jgz #84

Closed justachetan closed 9 months ago

justachetan commented 9 months ago

Hi! Are the camera poses (rotation and translation vector) listed in frame_annotations.jgz file in each category sub-folder in the world-to-camera format or the camera-to-world format?

Any help on this would be much appreciated!

The cameras are in Pytorch3D format, and if you use the provided data loaders, they will be loaded correctly. In case you use different frameworks, it should be: x_cam = x_world @ R + T (and then decalibrate with intrinsics if needed). More info: https://pytorch3d.org/docs/cameras
