摘要
该文主要针对1:5万地形图进行研究,是为提高等高线断线的连接率而进行的一种预处理算法,并首次提出了在等高线识别中先进行计曲线和首曲线分类的思想。该算法根据等高线的宽度信息能正确地区分计曲线和首曲线,为等高线的正确连接提供了依据,可以避免计曲线和首曲线之间的误连。
This paper mainly aims at the terrain map of1:50000rates.It's a pre-processing algorithm for raising the connection rate of contour.A new idea which is to classify the contour before its recognition is presented in this paper.It can correctly distinguish wide contour from thin contour according to the width information of contour.People can correctly connect contour by using the information,avoiding wrong connection between wide contour and thin contour.
