摘要
在GIS地图矢量化中,由于原始数据的获取,软件算法精度等原因使得矢量图形存在误差,本文阐述了模糊模式识别方法的原理,探讨了利用模糊模式识别对一些常用图形(矩形、圆、三角形等)进行矫正的方法,并应用于对一些具有模糊特征的地物边界进行判别。
In the GIS map vectorization process,this is error in map vectorization because of the primary data gain and the soft- ware algorithm precision..In this article,it has elaborated the fuzzy pattern recognition methods principle and discussed the method of using fuzzy pattern recognition to correct some commonly used graphs(rectangle,circle,triangle and so on),and used in the fuzzy characteristic place thing boundary to some to carry on the distinction.
