摘要
There should be high resolution demand that is better than 1000 DPI(dot per inch) for high precision image scanning system. This paper introduced the two-level computer controlled system that consisted of LS-3500 film scanner, AST386/33 monitoring control level and Intel 8031 single chip computer that is used as DDC level. The formula for scanning image data processing and methods of statistic parameters calculating are described.
本文论述了采用高分辨率ＬＳ—３５００图象扫描仪．由Ｉｎｔｅｌ８０３１单片机构成的ＤＤＣ控制的输片系统，以及ＡＳＴ３８６／３３主控计算机作为监督管理级共同组成的一套用于铁路隧道宽度测量的高精度图象扫描控制系统，深入讨论了扫描图象点阵数据处理方法及图形坐标的计算方法，计算结果达到和超过了设计要求．
