Dear Author @yinyunie ,

I have a hard time to figure out the relation between these three rotation matrices as shown in

https://github.com/yinyunie/Total3DUnderstanding/blob/bf6c8a92d421e58727a8288a5f8849da408c556e/utils/sunrgbd_utils.py#L379

BTW, the reference that I am currently using to interpret different kinds of coordinate systems is https://github.com/facebookresearch/votenet/blob/main/sunrgbd/sunrgbd_utils.py

Therefore I am kindly asking whether you could elaborate a little bit on how to interpret these three coordinate systems.
Best!
