About suface_normal Prediction
Hello, JiaxiongQ! when i read your code, i found that after you predict the surface normal vector, you perform some transformation operations on it. the code is: outputN = torch.zeros_like(normals2) outputN[:,:,:,0] = -normals2[:,:,:,0] outputN[:,:,:,1] = -normals2[:,:,:,2] outputN[:,:,:,2] = -normals2[:,:,:,1] I'm confused about this part. Can you explain it，Thank you very much.
When estimating the ground-truth of surface normal from depth, we did the same operation to generate the color we want. So the surface normal from predicted depth should do this operation again.
Can you explain your method to estimate the ground-truth of surface normal from depth? Thanks a lot.
For KITTI, we fitted a plane for sparse depth points in a window. Please vist https://github.com/Cindy-xdZhang/surface-normal for details.

thanks for your reply! I have ran the above code, but i wonder, numerically, what should f, fx, fy of the nuydepthv2 dataset be? (like 1, 1, 1, or some other numbers?)
You can find these parameters in their official toolbox.
