| Abstract: | A convetional CCD precise size measuring system fail to solve noise countermeasure problem. To meet the practical use of CCD measure system, the adaptive Kalman filter was introduced to the measure system, and as a result, the auti noise problem was solved.The system has high accuracy and confidence in the CCD measure system,its scope of application has been widen. |
