Abstract： Introduces the design of one width measuring device， based on TMS320F2812 DSP and linear CCD image sensor， with the advantages of non-contact and on-line measurement. The device is composed of CCD timing driving， pixel data acquisition and output control. By virtue of high processing speed of DSP and simple but effective width algorithm， motion product's dimension measurement and control are come true. It can be proved that this system has good qualities of simplicity， reliability and high performance /cost ratio， and can better satisfy the requirement of measurement on precision and speed.
