kitti depth ground_truth generator

[FrancsXiang]

I am a graduate student from China,XTU.I am puzzled about the method generating kitti ground_truth.I use the kitti raw lidar data,but the depth_maps are sparse.
I will appreciate it if you have any time to deal with it.

In the training, we use the sparse gt depth data. The invalid points are ignored in the loss.
