A Computer Vision Based Thematic Map Reading System

    Graphical Abstract
    • Abstract
  • 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.
