摘要
提出了一种基于颜色特征的地形图要素自动分层的方法 ,并针对地形图上的图形要素特征 ,提出了对等高线分版图进行后处理的算法 。
In order to realize full automatic digitization of color relief map, automatic color separation of scanned color map is of significance. Based on chromatics, colorimetry, collection and color of relief map, this paper presents a method of relief map image segment by essential factor that has different colors. Then a series of algorithm are given to process contour map that has less information than the original color map. Finally, the methods and algorithm mentioned above are verified.
