Summary: | The method involves measuring angular coordinates of target (2) in first angular position of deflector, as first position, and measuring angular coordinates of target in second angular position, as second position. The deflector is rotated with respect to second position such that sighting axes (3,22) in both layers is approximately in same direction. The measurements are performed using images captured by camera (4) whose optical axis is deflected by deflector. A calibration parameter is determined based on angular positions and angle of coordinates, by compensation calculation. Independent claims are included for the following: (1) calibration system; (2) calibration target board; and (3) computer program product for spatial measurement of object. |
