[0047] The specific implementation of the present invention will be further described in detail below regarding the technical solution for large field of view measurement of cylindrical workpieces and the light strip pictures taken by a single camera in the binocular stereo vision measurement system. Since the characteristic information is captured by the CCD camera after the laser light strip is reflected on the surface of the workpiece with a certain shape, the gray energy of the cross-section of the laser light strip captured by the CCD camera is accompanied by the information of the surface shape of the workpiece. Considering the actual space position and the workpiece Surface laser reflection characteristics, analyzing the workpiece shape information attached to the laser light stripe gray energy on the image, can establish the gray energy distribution model of the light stripe section on the image.
