Abstract

The invention discloses a road sign generation method and device for a high-precision map, electronic equipment and a storage medium, and the method comprises the steps: determining a to-be-processed video file according to pre-recorded track point information, and enabling a key frame in the video file to be used for determining an image containing a target road sign; converting the pixel coordinate of the target road sign into a latitude and longitude coordinate corresponding to the pixel coordinate point; according to the latitude and longitude coordinates corresponding to the pixel coordinate points, the relative position of a preset road sign and the relative position of a road sign belonging to the same type as the preset road sign are obtained, and each road sign has a relative position relation with the latitude and longitude coordinates of the pixel coordinate points; and according to the relative position relationship, generating a plurality of road signs for loading in the high-precision map. According to the method, the target road sign is directly generated according to the video file, and the error rate of the generation process is low.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a method, device, electronic device, and storage medium for generating road signs for high-precision maps. Background technique [0002] HD maps are usually machine-oriented maps for autonomous vehicles, with high-precision coordinates, as well as accurate road shapes, with detailed information about each lane. [0003] In the related art, in the process of making a high-precision map, the producers watch the video and then compare the base map obtained in advance, and click and edit the corresponding road signs in the corresponding position in the picture, and then manually complete the whole process manually. . [0004] However, due to the manual determination of the position, the deviation is usually large, and omission is easy to occur. SUMMARY OF THE INVENTION [0005] Embodiments of the present application provide a method, device, electronic device, an...
