Abstract: A map construction method and a related apparatus are provided. The method includes: obtaining, based on manual driving track data and/or an obstacle grid map, road information, intersection information, and lane information of a region through which a vehicle has traveled; obtaining road traffic direction information based on the manual driving track data and the road information, and obtaining lane traffic direction information based on the lane information and the road traffic direction information; obtaining intersection entry and exit point information based on the intersection information and the lane traffic direction information; and performing, based on the intersection entry and exit point information, an operation of generating a virtual topology center line to obtain an autonomous driving map of the region through which the vehicle has traveled, where the virtual topology center line is a traveling boundary line of the vehicle in an intersection region.

Abstract: A positioning method includes calculating, based on data that is of collection points at a road edge and that is collected by a radar, a feature of a road on which a terminal device is actually located, determining, from a plurality of candidate roads based on the feature of the road on which the terminal device is actually located and features of the plurality of candidate roads, a target road matching original positioning coordinates of the terminal device, and correcting the original positioning coordinates using the target road, to obtain corrected positioning coordinates.
