Hi,
Were you able to solve this problem? I came across the same issue with rgb_loss always evaluates to 0 on other images. More specifically, the network_object_mask
in rgb loss function seems always zero everywhere.
In preparing the images I arranged them in DTU style with images and masks. And populated cameras.npz
with world-to-image projection matrix and object-to-world scale_mat
, with the object coordinates confined in a unit sphere.
Edit: I just realised I had used the wrong coordinate system for camera projection. After correcting this the rgb_loss becomes non-zero.

Hi! How did you finally solve this problem? What is the correct coordinate system for camera projection? How do I get the initial world_mat in cameras.npz?

Hi!Could you tell me in detail which part of your negligence caused the calculation to be incorrect? I also faced the same problem and it bothered me for a long time
