Abstract

The present invention discloses a map element extraction method, device and server. The map element extraction method includes: acquiring a laser point cloud and an image of a target scene, the target scene including at least one element entity corresponding to a map element; performing the registration between the laser point cloud and the image to obtain a depth map of the image; image segmentation is performed on the depth map of the image to obtain a segmented image of the map element in the depth map; according to the The registration relationship between the laser point cloud and the image converts the two-dimensional position of the segmented image in the depth map into the three-dimensional position of the map element in the target scene. The method, device and server for extracting map elements provided by the present invention solve the problem of low production efficiency of high-precision maps in the prior art.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a map element extraction method, device and server. Background technique [0002] A high-precision map is a map used for assisted driving, semi-autonomous driving, or unmanned driving. It consists of a series of map elements, including: lane lines, ground markings, curbs, fences, traffic signs and other elements. [0003] Usually, in the process of generating a high-precision map, map elements are first extracted from the laser point cloud, and then the extracted map elements are manually edited to generate a high-precision map. It is understandable that if the accuracy of map element extraction is not high, it will result in long time-consuming manual editing of map elements, complex procedures, low efficiency, and ultimately affect the production efficiency of high-precision maps. [0004] Therefore, how to improve the production efficiency of high-precision maps sti...
