DATA PROCESSING METHOD AND APPARATUS

WIPO Patent Application WO/2022/078301

A1

A data processing method. The method comprises: acquiring first map data and positioning reference data (101); on the basis of the first map data, determining first map coordinates corresponding to a first trajectory point, and on the basis of the positioning reference data, determining first reference coordinates corresponding to the first trajectory point (102); correcting the first map data according to the first map coordinates and the first reference coordinates, so as to obtain second map data (103); determining a target object corresponding to a second trajectory point, and determining relative pose information of the second trajectory point and the target object (104); on the basis of the positioning reference data, determining second reference coordinates corresponding to the second trajectory point (105); and correcting the second map data in view of the second reference coordinates and the relative pose information, so as to obtain third map data (106). By means of the method, first map data is corrected to be third map data after a map error is eliminated. Further provided are a data processing apparatus, a vehicle and a computer-readable storage medium.
