摘要
This application provides a positioning correction method and apparatus, to correct a positioning track obtained based on a base station positioning technology. In this solution, after determining a moving path of a terminal device, a positioning correction apparatus determines, in the moving path, target road sections corresponding to a plurality of measured locations of the terminal device; the apparatus selects, from the plurality of measured locations, a measured location whose distance to a projection location of the corresponding target road section is less than a specified threshold as a reference location; and the apparatus determines, in the moving path, that corrected locations of the plurality of reference locations are projection locations of the plurality of reference locations in the corresponding target road sections, and determines a corrected location of another measured location in the moving path based on timestamps of the plurality of measured locations and the corrected locations of the plurality of reference locations. According to the foregoing solution, the apparatus can determine a corrected location of each measured location in the moving path, to correct the positioning track obtained based on the base station positioning technology.
