get the pixel coordinates and then assign to each pixel depth value

[Jezer-Zhang]

hi, i am trying to extract one channel tensor form lidar samples, containing the depth value (z) in corresponding pixel coordinate. is there any developer that can help?

@Jezer-Zhang one possibility is to refer to map_pointcloud_to_image to figure out which image pixel each lidar point falls in
