About the 3D bounding box coordinate system of point cloud #40
Description
First of all, thank you for providing this platform.
I am using your platform to annotate 3D bounding boxes for point cloud data, but I am somewhat confused about the reference coordinate system for the orientation of each bounding box.
According to the documentation you provided, the rotation angle of the bounding box around the z-axis is 0 when facing the +y direction. Is this y-axis referring to the y-axis of the ego-vehicle coordinate system?
