摘要
为了弥补车辆导航中位置点匹配算法的不足,对轨迹曲线匹配的思想进行了必要的介绍,并重点从距离要素出发,对匹配准则进行了研究。在分析了各种常见距离定义的不足后,提出了基于面积法的距离匹配准则,并对距离准则的算法设计和适用性进行了详细的分析和描述。结论表明,采用该算法后的总体定位精度优于GPS的定位精度,算法准确性也比位置点匹配高。
In order to improve the point-matching algorithm in vehicle navigation systems, this paper introduces as a basis the idea of trace-curve matching, and explores the matching principles by focusing on the main distance factors. According to an analysis of the shortcomings of the normal distance definitions, the paper proposes an area-based distance matching standard, and describes in detail the design algorithm of the distance matching standard and its applicability. It is concluded that the total positioning preciseness of the proposed algorithm is better than that of the GPS methods, and the accuracy of the algorithm is higher compared with that of the point matching.
