Box pose transfomation from camera 2 to velodyne may not be correct.

[AlfredQin]

Hi, I found code at

dd3d/tridet/data/datasets/kitti_3d/build.py

Line 260 in 86d8660

 box_pose = pose_0S * pose_02.inverse() * box_pose 

may not be correct.
If we want to get the box pose in the velodyne frame, I think the code may be box_pose = pose_0V.inverse() * pose_02 * box_pose.
I am not sure if it is correct, so I hope you can double check, thank you!
