Paper Abstract

This paper presents the design of the 2D laser distance sensor based on the laser triangulation principle. The hardware structure of the sensor and the signal processing circuit based on DSP and FPGA are designed. A CMOS image sensor is used to grab the laser light image of the laser line on the object. The pixel positions of the laser line in the grabbed image are extracted by image processing methods. In order to improve measuring precision, the geometric distortion of the original image is corrected and the system parameters of the sensor are calibrated. Experimental results demonstrate that the devised sensor can work at high-speed with high precision.
