Abstract
A method for vehicle positioning is provided, which includes the steps of identifying at least one vehicle in an image, obtaining identification information of each vehicle from the image, and transforming coordinates of each vehicle in the image into positioning information of the corresponding vehicle according to mapping information. The positioning information is a position of the corresponding vehicle in real world. Precise lane-level vehicle positioning can be achieved based on comparison with the identification information or the positioning information.
