Paper Abstract

The CCD camera is being used more and more widely now. In the technology of space flight, each line's distance of a picture taken by a CCD camera is in direct propagation to the ratio of the flying altitude and flying speed of an airplane when a CCD camera is taken a picture of the ground. But this ratio is constantly changed as the atmospheric changing and some reasons of the airplane. Therefore, we should measure and record the ratio on time for the purpose of reappearing the picture correctly. Because of the moving speed of a picture is related to the ratio, we must measure the speed accurately. This paper introduces the principle and the method of measuring the moving speed of a picture by means of a CCD camera. The overall structure of system, the error analyses have been given in the paper.
