Track similarity calculation method, device and equipment and computer readable storage medium

The embodiment of the invention discloses a trajectory similarity calculation method, a trajectory similarity calculation device, computer equipment and a computer readable storage medium. The trajectory similarity calculation method comprises the following steps that a data point set of a processing object is obtained, the data point set comprises a plurality of first data points, a dynamic distance threshold value is obtained according to time information and speed information of every two first data points, abnormal data points in the data point set are screened out, and second data points are obtained; obtaining a first track of the processing object according to the second data point; obtaining a second track, wherein the second track is composed of a plurality of third data points; obtaining a time threshold value, and selecting a fourth data point from the plurality of third data points according to the time threshold value; and calculating the second data point and the fourth data point through a pres
