摘要
彩色地图是用不同的颜色表示各个数据层,可以利用颜色信息有效地实现地图各个数据层的自动提取。本文用分光光度计对待扫描的标准色块进行颜色测量,然后用最小二乘法建立起颜色RGB分量与颜色三属性(HVC)的关系,并提出了一种识别地图颜色的新方法。
Usually each color represents a data layer in a color map, so the automated segmentation of scanned color map can be done using the color information. In this paper, the color chart is measured by colormeter instrument and the function is built between RGB values of a color and HVC by least squares approach. Finally a new color separation method of scanned map is presented and the map elements are segmentated automaticlly.
