摘要
在各类城市地图中,曲线、区域、符号、标注混杂,通过计算机完全自动地识别是很困难的。本文介绍一种基于人机交互方式的地图识别方法,该方法包括两个算法,即对线条的截断跟踪识别算法,和对线宽的区域生长识别算法。经实验证明,该方法具有识别速度快、对地图扫描图像质量的要求低等特点。
On various sorts of city maps, curves,regions, symbols and labels are mixed up to some extent with each other. It's very difficult for the computer to recognize all the objects on the map automatically. In this paper, a human- computer interactive vectorized recognition method of maps, which includes two algorithms, is provided. The first one is a segment tracing algorithm which is for the recognition of line objects; and the second one is a region growing algorithm which is designed to recognize the line width.Experimentation shows that the method has the features of speediness and exactness in recognition as well as low request for scanned image quality.
