摘要
本文提出了一种基于计算机视觉的专题图读取系统方案。该系统用CCD相机获取专题图影象,通过线划跟踪、弧段矢量化、拓扑结构形成、数据压缩、几何纠正与拼接等步骤,实现专题图的自动读取,继而进行各种几何量算和统计。
This paper presents a computer vision based thematic map reading system. It gets images from CCD camera. The thematic map is automatically read through a series of data processing procedure, such as line following, arc vectorization, to pological sturcture generation, data compression geometrical rectification, mosaicing and so on. In this system, areas and lengthes are measured automatically and statistical information are generated for the thematic data base.
