The extrinsic matrix consists of a unitless 3 x 3 rotation matrix (
R) on the left and a 3 x 1 column vector translation (
t) on the right. The translation vector's units are millimeters.
The camera's pose is expressed with respect to a reference camera (camera-to-world view). If the rotation matrix is an identity matrix, then this camera is the reference camera. (Note that a
matrix matrix is column major with 3 rows and 4 columns.)
