34 A camera sensor has a 2-dimensional reference system 'Rc' defined by its
35 pixel array read-out order. The origin is set to the first pixel being
36 read out, the X-axis points along the column read-out direction towards
37 the last columns, and the Y-axis along the row read-out direction towards

52 The external world scene reference system 'Rs' is a 2-dimensional
54 placed on the top-left corner of the visible scene, the X-axis points
55 towards the right, and the Y-axis points towards the bottom of the scene.
56 The top, bottom, left and right directions are intentionally not defined
60 to right, as seen from the camera, is:
