The invention relates to an abnormal track identification method and device, computer equipment and a storage medium. The method comprises the steps of obtaining track information of a target vehicle, wherein the track information comprises first position information of a current frame, second position information of a previous frame of the current frame and third position information of a next frame of the current frame; determining a first movement vector according to the first position information and the second position information; determining a second movement vector according to the first position information and the third position information; and when the vector angle between the first movement vector and the second movement vector is greater than or equal to a vector angle threshold value, determining that the trajectory of the target vehicle is abnormal. The method can be used for identifying the track abnormity.

    本申请涉及一种异常轨迹识别方法、装置、计算机设备和存储介质。方法包括:获取目标车辆的轨迹信息,所述轨迹信息包括:当前帧的第一位置信息、所述当前帧的上一帧的第二位置信息,以及所述当前帧的下一帧的第三位置信息;根据所述第一位置信息和所述第二位置信息,确定第一移动向量;根据所述第一位置信息和所述第三位置信息,确定第二移动向量;在所述第一移动向量和所述第二移动向量之间的向量角度大于或等于向量角度阈值时,确定所述目标车辆的轨迹异常。采用本方法能够识别轨迹异常。
