| 摘 要： | 文章以扫描输入的大比例彩色地形图为研究对象,重点讨论了彩色地形图中等高线的计算机识别方法,提出了基于方框邻域内点的算法,针对分色后提取出来的等高线二值图像进行识别和处理,使等高线中的首曲线和计曲线区分开来,以达到计算机可以识别的目的。同时该算法和思想还具有通用性,可以推广到其它有关曲线图像粗细识别中去。

| Abstract: | The paper mainly aims at the large scale multicolor relief map that is scaned into computer and discusses the recognition of contour line in multicolor relief map for computer.A algorithm based on nearby points is put forward. The method can distinguish wide contour line from thin contour line in image which has been picked-up from scaned relief map.At the same time,the method can be extended to other image recognition field that is relative with wide line and thin line. |
