The invention belongs to the technical field of intelligent lighting, and particularly relates to a lane lighting method and system based on vehicle foresight visual perception, and the lane lighting method comprises the following steps: carrying out site calibration on the basis of a vehicle foresight visual perception system, and obtaining a transformation relation between a camera image coordinate system and a vehicle lamp image coordinate system; obtaining a detection result of each frame of lane line under a camera image coordinate system through vehicle foresight visual perception; if the vehicle is located between the left and right lane lines, triggering a lane lighting function; calculating lane lines in a vehicle lamp image coordinate system according to the conversion relation between the camera image coordinate system and the vehicle lamp image coordinate system of each frame of lane lines in the camera image coordinate system; and controlling the HD matrix headlamp to project light in a lane range according to the lane lines under the vehicle lamp image coordinate system through the controller. According to the method, the lane line detection result is combined with the HD matrix headlamp technology, accurate light beam control is carried out according to the lane shape, the visual blind area is avoided, and the driving safety is improved.
