The invention discloses a high-speed user moving trajectory validity judgment method, which relates to the technical field of moving trajectories and comprises the following steps: acquiring a moving trajectory, and sequentially extracting a plurality of positioning points; a previous positioning point is known as an effective point, an adjacent positioning point is selected backwards, a weight positioning point of two adjacent positioning points is calculated, the offset distance between the weight positioning point and the next positioning point is calculated, (a) the next positioning point is the effective point if the offset distance is within an offset threshold value, and (b) the next positioning point is the effective point if the offset distance exceeds the offset threshold value. If yes, the next positioning point is a suspected offset point, extracting a new positioning point, calculating a weight positioning point of the previous positioning point and the new positioning point and an offset distance between the weight positioning point and the new positioning point, and continuing to extract the new positioning point until the new positioning point is an effective point if the offset distance still exceeds an offset threshold value. And when five continuous positioning points are judged to be effective points, judging that the moving trajectory where the five positioning points are located is an effective trajectory. According to the invention, the accuracy of the moving trajectory can be improved.
本发明公开一种高速用户运行轨迹有效性判断方法,涉及运行轨迹技术领域,包括:获取运行轨迹,依次提取多个定位点;已知前一个定位点为有效点,向后选取相邻的一个定位点,计算相邻两个定位点的权重定位点,计算权重定位点与后一个定位点的偏移距离,(a)偏移距离在偏移阈值内,则后一个定位点为有效点,(b)偏移距离超出偏移阈值,则后一个定位点为疑似偏移点,提取新定位点,计算前一个定位点与新定位点的权重定位点、权重定位点与新定位点的偏移距离,偏移距离仍超出偏移阈值,继续提取新的定位点,直至新的定位点为有效点。直至连续五个定位点被判定为有效点,则判定该五个定位点所在运行轨迹为有效轨迹。本发明可以提高运行轨迹的准确率。
