lift operation (LSS) in the image #23

I see that lifting operation used LSS method in the code, but it has changed a lot compared with the vinilla version. Can you roughly describe the changes in thinking or related documents? Thanks a lot.

Sorry for the late reply, the lifting operation is heavily borrowed from the BEV community (BEVDet/BEVerse/BEVFusion), and the core idea is similar, except that we maintain the z-axis information. (Noted that the lifting operation is not claimed as one contribution in our paper.)
