仿射变换在电子地图中的应用

随着微电子技术、计算机技术、空间技术及制图技术的发展,车辆定位系统可确定行驶在每个街道和十字路口车辆的准确信息。然而,控制中心接收到的是经纬度数据,电子地图定位的是坐标数据,如何实现两者之间对应数据的转换?利用仿射变换实现了两者之间数据的转换,并用作者所开发的一个系统加以验证。

Application of Affinity to Electronic Map

With the development of microelectronic technology,computer technology,space technology and mapping technology,vehicle positioning system can get the accurate information of vehicles in every street or crossroads.However,the control center receives the latitude and longitude data,but the electronic map system operates the coordinate data,how to implement the conversion between the two types of data is a problem.This paper use affinity to solve the problem,and verify it in an experimental system developed by author.
