描述车辆轨迹描绘的特点,分析逐点判断法及多点联合判断法的优缺点,提出利用拐点判断法对轨迹进行描绘的方法.实测数据分析表明,在保证轨迹恢复达到一定精度要求的前提下,利用拐点对定位信息进行精简是可行的,采用联合判断法比逐点判断法更准确、压缩比更高.

This paper describes the delineative characteristics of vehicle track, analyzes the advantages and disadvantages of point-by-point judgment method and combined judgment method, and presents the method of using turning point judgment to delineate the track. Analysis on measured data shows that it is feasible to simplify the location data with turning point, meanwhile combined judgment method is more accurate than point-by-point judgment method, and it has higher compression ratio.
