Trajectory fitting method and device, electronic equipment and storage medium

Abstract

The invention provides a trajectory fitting method and device, electronic equipment and a storage medium, and relates to the field of path data processing of traffic management. The trajectory fittingmethod comprises the steps of preprocessing trajectory data of a target vehicle to obtain a to-be-processed trajectory point set; acquiring first road grabbing information of the first track point set according to the road network mapping data of the monitoring area; obtaining a target path combination through which the target vehicle passes according to the first road grabbing information, wherein the target path combination comprises at least one road; and fitting the to-be-processed track point set in the target path combination to obtain a fitting track of the target vehicle in the monitoring area. By using the trajectory fitting method provided by the embodiment of the invention, the dense trajectory points of the vehicle can be removed, and the road network mapping data of the monitoring area can be called, so that the fitting of the vehicle trajectory is realized, and the trajectory fitting efficiency is improved.

Description

Technical field[0001]This application relates to the field of path data processing for traffic management, and specifically, to a trajectory fitting method, device, electronic equipment, and storage medium.Background technique[0002]With the development of society and economic progress, there are more and more public transportation vehicles and household vehicles, and traffic roads also cross vertically and horizontally. How to manage the trajectory of vehicles on the road and establish vehicle trajectory data has become a current research problem.[0003]In the current technical solution, the operators mark each trajectory point data of the vehicle in the map data, resulting in the generated vehicle trajectory is relatively scattered; for example, when the vehicle passes through the toll station, due to the slow speed of the vehicle, the waiting time is long, resulting in With a large number of dense track points, the vehicle track is not clear.Summary of the invention[0004]The purpos...
