A positioning system comprises a pattern projector (70) for projecting a 2D/3D pattern (45) onto an object surface. The 2D/3D pattern (45) is detected by a detector (80, 85), which generates a detection signal that is employed by a pattern analyzing circuit (110) for generating a surface representation of the object surface. A correction analyzing circuit (130) generates a correction signal representative of a discrepancy in position and/or posture of the surface representation relative a stored reference surface representation. The correction signal is employed to generate information (55, 56) that is projected by a light projector (70, 75) onto the object surface. The projected information (55, 56) is indicative of the determined discrepancy in object position and/or posture. |
