Title: METHOD AND DEVICE FOR DETERMINING LANE CENTER LINE
Abstract:
A method and a device for determining a lane center line. The method comprises: acquiring a target lane in a road segment in which the number of lanes change, the target lane referring to a lane to be added or reduced; with regard to the first end of the target lane, determining the middle point of the two endpoints of the lane lines at both sides of the target lane at the first end as the center endpoint of the first end; with regard to the second end of the target lane, determining the lane center point of an adjacent lane of the target lane as the center endpoint of the second end; and determining the lane center line of the target lane on the basis of the two center endpoints. With regard to a lane to be added or reduced in a road segment in which the number of lanes changes, the solution provided by the embodiments of the present application determines the lane center line of the lane, and can guarantee that the lane center line of the lane and the lane center line of a lane connected thereto are continuous, improving the accuracy of determining the lane center line. Furthermore, the solution provided by the embodiments of the present application completely uses automated calculation, without the need for manual intervention, improving the efficiency of determining a lane center line.
