About "nerf_pose_to_ours" #86

Open DRosemei opened 2 years ago

Thanks for your great work! I found that you use nerf_pose_to_ours to convert poses from OPENGL coordinate. I want to konw how your coordinate define here and your special NDC coordinate define with respect to the sparse grid. I want to init some sparse keypoint in sparse grid and I could not find correspondency. Thanks in advance!

Hi, @DRosemei have you figured out this issue? I also have the same question on what coordinate it converts to.

Hi, I had the same issue when creating my own llff dataset that had opencv coordiates and eventually used the inverse transform to the one applied in nerf_pose_to_ours. Please note there is another coordinate transformation in load_llff_data. So you need to apply the inverse of both of these in opposite order
