| 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。

| Abstract: | In order to improve the point-match-ing 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 fac-tors. According to an analysis of the shortcom-ings of the normal distance definitions, the pa-per proposes an area-based distance matching standard, and describes in detail the design algo-rithm of the distance matching standard and its applicability. It is concluded that the total posi-tioning preciseness of the proposed algorithm is better than that of the GPS methods, and the ac-curacy of the algorithm is higher compared with that of the point matching. |
