Abstract: This paper studied the key technologies of 3D surface measurement system based on linear structured light vision sensor, and effectively achieve the integrity measurement of curved surface. The establishment of the line structure light 3D surface vision measurement system with three coordinate measuring machine for motor drive and control device, effectively with high precision motion measurement machine control characteristics applied to 3D surface scanning measurement. The mathematical model of the measurement system is proposed and its working process is described in detail. Calibration of camera calibration for vision measurement system and visual sensor structural parameters were introduced.

Keywords: Three dimensional vision measurement; line structured light; camera calibration; light plane calibration
