Planning method and system for realizing intersection passage based on lightweight map, and medium

The invention relates to a planning method and system for realizing intersection passage based on a lightweight map, and a medium, and the method comprises the steps: U1, enabling a vehicle to drive to an intersection, obtaining the map data information of an intersection region in real time based on a vehicle-mounted lightweight map, obtaining the image data information of a road in real time based on a vehicle-mounted camera, and obtaining the image data information of the intersection region; inputting the image data information of the road into a lane line identification network model for identification to obtain the image data information of the lane line of the current road; and U2, based on the image data information of the current road lane line, calculating and optimizing the driving track of the vehicle in front of the intersection by adopting a lane line track fitting algorithm to obtain first traffic optimization track data information of the vehicle. According to the method, the problems that a h
