When the dimension of measurand is measured with a charge couple device (CCD), the measuring accuracy is limited in interval of array photosensor. It we want to improve the measuring resolution, we often finish it by improving the magnifying power of optical system. But if we do this, we shall limit the measuring range of CCD. If using a analog- digital converter, we can get the pulse amplitude of CCD array photosensor. Using numerical method to the pulse amplitude, we can change intersect value to continuous value. With the segmentation level, we can get a improving resolution. In this paper, we give a hardware frame chart and the calculation course.
