Could anyone kindly tell me that in the statement that “This information is used by computer vision users. The positions and rotations of the cameras are defined in a local coordinate system. In order to get the values in the definition mentioned in How are the Internal and External Camera Parameters defined? article, the rotation around the X-axis and the offset needs to be applied.”, what is the local coordinate system referring to? Camera coordinate (have z-axis point to camera) or body coordinate ( have z-axis point to scene )?
Any hint will be grateful.
