| 摘 要： | 彩色地图扫描数据自动分层是全自动地图数字化的关键技术之一。作者在研究了彩色地图扫描数据中客观存在的颜色误差后，指出仅用颜色这一单一判据很难实现彩色地图扫描数据的分层；同时研究出了顾及彩色地图颜色特点、利用地图知识辅助的彩色地图扫描数据的自动分层。此外，本文还提出了一种适用于彩色地图扫描数据的按颜色分类的快速算法。

| Abstract: | The segmentation of scanned color map data is the first step for transferring the map data into GIS. In this paper, the author concludes that it can not realize the segmentation of color map only using color, after analyzing the color errors existing in the scanned data. At the same time, a new method for color map segmentation is put forward, in which the map knowledge is used and the speciality of the color map is also considered. Besides that, the author also puts forward a color classification method, which is simple, fast as well as suit for color map. |
