Abstract： The system is constructed of MCS-51 computer、CCD、tele-centric system . Operated by the computer, the system may detect the axis line of a work-piece and it's movement. The small interval of the work-piece may be fast measured. In this paper,The authors describe the sensor principle、interfere circuit of CCD to computer、hard and software of the measuring system.
