Abstract

The invention relates to a lane line generation method and system. The method comprises the following steps that: an image containing a lane line collected during the driving of a vehicle and geographical position information of the vehicle are acquired; the image is identified, pixel coordinates of pixel points of a lane line in the image can be obtained; according to the pixel coordinates of thelane lines and the corresponding geographic position information, space coordinates of the two lane lines of a lane where the vehicle is located currently are obtained through calculation; whether the space coordinates of the two lane lines are stored or not is searched; if the space coordinates of the two lane lines are not stored, the space coordinates of the lane lines are stored; and for thelane lines with the stored space coordinates, space coordinate optimization processing is performed on the lane lines according to a preset rule. According to the method and system provided of the technical schemes provided by the invention, the lane lines required by a high-precision map can be manufactured based on video data and positioning signals acquired by the single vehicle. The method andsystem have the advantages of low manufacturing cost, short processing flow, simple algorithm and high efficiency, and greatly shorten the manufacturing and updating period of the high-precision map.

Description

technical field [0001] The present application relates to the technical field of navigation, and relates to a method and system for generating lane lines. Background technique [0002] In related technologies, high-precision maps are produced by collecting vehicles equipped with panoramic cameras, binocular cameras and other equipment, which has high production costs, lengthened processing procedures, complex algorithms, and low efficiency, which restricts the production and update cycle of high-precision maps.
