| Abstract: | This paper discusses a new method to read the film dot pattern information which uses CCD matrix camera to acquire image and adopts the analyzing methods of digital image-processing techniques. This method can be used to read the dot pattern information of any kind of high-speed photograph and cine theodolite film accurately and quickly. Moreover the reading system is very simple and has a high cost performance ratio. In this paper the working principle of the CCD image processing system is analyzed first, and then the processing method of film dot pattern image is discussed in detail. |
