摘要
针对GPS数据丢失导致的出租车轨迹失真问题,本文提出了邻域等比补齐算法。该方法根据邻域轨迹的运动状态在时间上具有连续性的特征,利用邻域轨迹的等比例位置采用线性插值来获取补齐坐标。本文采用大连市中山区2015年3月1日的出租车GPS轨迹数据中的57组数据进行试验,补齐数据与真实数据对比,26%数据误差在20m以内,46%数据误差在20～50m。本文提出的邻域等比补齐算法具有较好的补齐效果。
To solve the problem of taxi track distortion caused by GPS data loss,a neighborhood equal-ratio compensation algorithm is proposed.According to the time continuity of the neighborhood trajectory,the complementary coordinates can be obtained by linear interpolation of the equiscalar position of the neighborhood trajectory.In this paper,57 groups of taxi GPS trajectory data from Zhongshan District of Dalian on March 1 2015 were used to conduct the tests.Compared with the real data,26% of the data errors are within 20 m and 46% of the data errors are between 20 and 50 m.The neighborhood equivalence ratio algorithm proposed has a better result.
