Research on the Method to Calibrate Structure Parameters of Line Structured Light Vision Sensor

The existing linear structured light sensor system calibration process to the equipment requirement is high, the calibration process such complicated problems, this paper puts forward a simple calibration method. Use of the most commonly used transit system, back light reflection artificial materials, as well as the independent development of photography calibration software, in a plane wall master three fine line, at the same time in space layout a filament, and the four o 'clock in the transit system of coordinates. Combined with camera coordinate system in the transit system of bearing, the light plane and unified camera, so as to get the light plane point in the camera coordinate system coordinates. Structured light system can be moved several position, get more sets of light plane, thus to find the mean value. The experimental data show that field calibration.CPCI-S(ISTP)18797396784@163.com; 13519755989@139.com; whuwan@163.com; liyan.@pku.edu.cn; 13589943826@163.com377-3822
