Can we extend Sparse4D to a new dataset? about sparse4d HOT 3 CLOSED

Any coordinate system that is fixed relative to the ego vehicle is fine, and the commonly used one is the "vehicle coordinate system".

from sparse4d.

As far as I know the camera coordinate system and lidar coordinate system are not fixed relative to the ego vehicle for all nuscenes data. So will we futher improve the mAP by changing lidar coordinate system into CAM_FRONT coordinate system?Thanks!

The camera coordinate system and lidar coordinate system are fixed relative to the ego vehicle. The reason why ego2cam and ego2lidar are changing is to synchronize the time of multiple sensors.

mAP does not vary with coordinate system changes.
