| 摘 要： | 介绍了基于GIS的飞行器定位系统的基本原理,研究了一种数字影像与GIS矢量数据的匹配方法.该方法采用局部最优与整体匹配相结合的匹配策略,利用数字影像上提取的线特征作为匹配的共轭实体,以线特征的角度、线特征的长度、相交线特征之间的夹角等作为匹配的匹配实体,通过计算匹配实体间的相似性测度实现共轭实体间的精确匹配.

| Abstract: | The principle of vehicle navigation based on GIS is introduced.In this paper a matching method of image and GIS data is put forward.This method adopts a matching strategy of local optimum and global matching combined.The line features extracted from the image are taken as conjugate entities,and angles and lengths of line features as matching entities.The accurate matching of conjugate entities is realized by calculating similarity measures of matching entities. |
