Track correction method and device, terminal and computer readable storage medium

Abstract

The invention provides a track correction method and device, a terminal and a computer readable storage medium. The track correction method comprises the steps that an initial track and a reference track corresponding to a target object in a preset area and a preset time period are obtained through different types of equipment; determining whether the initial trajectory is an abnormal trajectory based on the space-time similarity between each first trajectory point in the initial trajectory of the target object and the reference trajectory; in response to the fact that the initial trajectory of the target object is an abnormal trajectory, determining a fusion similarity between the object and the target object based on a space-time similarity between acquired data in a preset area and a reference trajectory and a target similarity between the object corresponding to the acquired data and the target object; and correcting the initial trajectory of the target object based on the trajectory information of the object corresponding to the fusion similarity. According to the method, the accuracy of the trajectory data of the target object is improved by performing anomaly detection on the initial trajectory of the target object and correcting the abnormal trajectory.
