| 摘 要： | 目前G IS数据大多采用矢量化来获取,但是曲线在采用自动跟踪矢量化时存在数据冗余等缺陷。本文基于逆向思维,采用了一种与多边形逼近法相逆的方法来提取不规则曲线的特征点。试验表明,该方法比角检测法和多边形逼近法的保真度要好。

| Abstract: | At present,most GIS data are obtained by vectorization.But there exists redundant data in the curve vectorization when adopting automation tracking.Based on reverse thinking,a new method,which is contrary to polygonal approximation,is proposed to extract irregular curve.It is indicated by experiment that the fidelity is greatly superior to polygonal approximation and corner detection approaches. |
