地图匹配算法分为在线和离线匹配，针对离线地图匹配中Marchal算法精度较低以及存在模糊多解的问题，利用伪Zenike矩对其进行改进，将行驶轨迹与道路曲线利用伪Zenike矩进行形状描述，然后对曲线进行特征匹配，获取道路点。实验结果表明，新算法可以较好地纠正矢量数据不完整时Marchal算法产生的错误结果，很大程度上提高了匹配的准确性，而且匹配的效率优于现有算法。

Map matching algorithms include on-line and off-line matching algorithms. Aiming at the problem of the lower precision and indistinct multiple solutions of Marchal’s off-line matching algorithm, this paper presents an improved map matching algorithm based on Pseudo-Zernike moments, which uses the Pseudo-Zernike moments to obtain the road points by describing the trace course and road curve and then carrying out feature matching. The results of simulation and experi-ment show that the new algorithm can correct the errors resulted from the incomplete vector map, it can improve the preci-sion of map matching greatly with higher efficiency better than the existing algorithm.
