According to the triangle measuring principle,a binocular stereo vision sensor made of one laser line projector and two CCD cameras is studied.The influence of position of CCD on measuring accuracy is discussed and the parameter is determined.Based on the previous study,its working processes are researched,including calibration of CCD cameras,acquisition of scanning image,feature extract ,feature matching and 3D data formation.Combining with scanning mechanism (for example CCM),the sensor can measure obje...
