Abstract

The invention provides a trajectory data supplementing method, which relates to the technical field of navigation, and can solve the problem of inaccurate historical trajectory data of a user caused by missing of trajectory points in the historical trajectory data of the user. According to the specific technical scheme, the track point information in a historical track of a user is obtained, a historical driving database is traversed, the target reference track points are determined according to preset rules, the target reference track points are supplemented to historical track data of the user, the historical track data of the target user are generated, and therefore supplementing processing of the historical track of the user is achieved. The method is used for supplementing the trajectory data.

Description

technical field [0001] The present disclosure relates to the technical field of navigation, and in particular to a trajectory data supplement method and device. Background technique [0002] With the increasing maturity of global satellite navigation and positioning systems such as GPS, Beidou, and GLONASS, people enjoy fast and accurate positioning services. The Beidou satellite navigation and positioning system is a global satellite navigation and positioning system independently developed and operated by China. Based on the Beidou high-precision positioning system, the Beidou Tiandi public location service platform realizes image display and data processing of the location information of personnel, vehicles and equipment distributed in various places on the electronic map. Database technology (Database) and network communication technology (Network) realize the functions of command, dispatch, monitoring and management, and establish a set of high-tech management system p...
