摘要
本文介绍了一种基于LBS的车辆监控系统,该系统采用了"点到点"路径匹配算法和"轨迹插值"轨迹回放算法,可有效提高定位精度和降低应用成本。
The vehicle monitor system based on LBS are introduced in this paper. Based on the idea of line-to-point set, ＂point-to-point＂ road matching algorithm and ＂trace interpolation＂ trace replay algorithm are designed. Applied to actual projects, ＂point-to-point＂ achieves a high accuracy, particularly at road intersections. The ＂trace interpolation＂ has greatly reduced the cost of positioning.
