The embodiment of the invention discloses a trajectory data processing method and device and related equipment, and the method comprises the steps: obtaining user behavior trajectory data, and obtaining user time information associated with the user behavior trajectory data; setting a plurality of time-space points according to the user behavior trajectory data and the user time information, wherein one time-space point corresponds to one position area in one time period; extracting a target representation vector corresponding to each time-space point according to the user trajectory data; andaccording to the target representation vector, respectively determining the access frequency between each time-space point and a plurality of position interest point categories. By adopting the method and the device, the accuracy of identifying the access frequencies of various POIs in different regions in different time periods can be improved.
