基于微机的快速数字地图修测系统的研究

The Investigation of a Fast Digital Map Revision System

根据彩色数字地图色彩的光谱特性，运用色度学和模式识别的基本原理，对彩色数字地图进行处理，把彩色数字地图数据自动分类、识别，获得了单要素层的数字地图，然后在微机上把它们和新的像片（正射影像）叠置，进行数字修测。

In this paper a method is described for color map segmentation by meansof the basic principles of colorimetry and pattern recongnition. The color map issegregated and recongnized in according with its spectrum, and then it can beoverlaid on the photo(orthophoto image)to perform map revision on computer.
