摘要
本文论述了一种判读胶片点阵信息的新技术．CCD点阵信息判读技术采用面阵CCD实时采集点阵图象，并结合数字图系处理技术，使点阵判读达到了通用性强、误码率低、处理速度高的水平，同时系统结构简单、成本低．本文在分析CCD图象处理系统原理的基础上，重点讲述了点阵图象的处理方法．
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.
