The ground truth of the depth map.

[loserhou]

Can you please tell me about the truth value of the depth map, after projection using Lidar point cloud, for points projected to the same pixel position, how is the depth of that position determined? Do you take the average or the closest or the farthest? I would like to get your answer , thank you very much!

Finally, for feature maps of different sizes, is the ground truth sampled directly to obtain the ground truth of the corresponding size?
