基于多假设的地图匹配算法。程序能够根据车辆在行驶过程中收集到的GPS/DR数据正确得到当前车辆所在的道路位置。-Assumptions based on multi-map-matching algorithm. Procedures in accordance with the process of vehicles moving collected GPS/DR data correctly be the current location of the vehicle s path.

GPS过滤算法代码，有参考代码和例子。项目中用的模块是UBLOX M6-GPS filtering algorithm code, reference code and examples.
