Question on projecting on segmentation map #36

Closed rod409 closed 1 year ago

Can you explain why you project the points on the segmentation map after they were already projected to camera coordinates? Start of the code I am confused about is below.

Never mind I understand from the KITTI paper that describes the projection matrices.
