摘　　要：导航定位系统是车载系统的主要组成部分,其中地图匹配又是提高定位精度的重要技术。从数字地图本身的属性特征出发,研究了一种基于曲率分析的地图匹配算法。通过车载实验数据对算法加以验证,其结果表明改进后的算法能够获得较高的定位精度和更可靠的匹配性能。The navigation positioning system is the main component of vehicle system, and the map matching is the important technology to improve positioning accuracy. From the attributes of digital map, one kind based on the curvature analysis of the map matching algorithm has been studied, through the vehicle of experimental data on the algorithm is verified, the results show that the improved algorithm can achieve higher precision and more reliable matching performance.
