Abstract
Disclosed is a vehicle positioning method and apparatus, a storage medium and an electronic device. The method comprises: prelocating a target vehicle in a running state based on a global positioning system to obtain a priori position of the target vehicle in a map; acquiring running image data collected by a camera sensor in the target vehicle in a target area where the priori position is located; visually recognizing the running image data by using a vector map of the target area, so as to acquire lateral position information and longitudinal position information about a position where the target vehicle is located currently; determining a target lane in which a target vehicle is located according to the transverse position information, and positioning a travel position of the target vehicle in the target lane according to the longitudinal position information. The present invention solves the technical problem in the related art that the positioning accuracy of a vehicle is relatively low on the premise that the costs are limited.
