How to implement the agreement between the lidar data and the label frame in the global coordinate system

[wbz0429]

I apologize for the disturbance. I want to use bounding boxes to filter LiDAR data points. I am using the transformation matrix from the LiDAR coordinate system to the camera coordinate system and the transformation matrix from the camera coordinate system to the map coordinate system to transform the LiDAR data points into the global coordinate system. Then, I transform the bounding boxes into the global coordinate system to achieve coordinate system unification. However, I have found that after the transformation, it seems that the coordinates are not unified. I am unsure where the issue lies, whether it is with my unification method or if there is another approach I should be using. I would greatly appreciate any help you can provide in resolving this issue. Thank you very much!
