Thank for the excellent work!
I have a question about code for coordinate system conversion in colmap2nerf.py
line63 :# Convert from COLMAP's camera coordinate system (OpenCV) to ours (OpenGL)
the OpenCV is RDF coordinate and the opengl coordinate is RUB
the code line 64 c2w[0:3, 1:3] = -1 has been completed the coordinate system conversion
the Subsequent code "c2w = c2w[np.array([1, 0, 2, 3]), :] c2w[2, :] = -1" What is it used to achieve？？？？
