Abstract

The invention discloses a map element extraction method and device and a server. The map element extraction method includes the following steps: obtaining a laser point cloud and an image of a targetscene, wherein the target scene includes at least one element entity corresponding to map elements; registering the laser point cloud and the image to obtain a depth map of the image; performing imagesegmentation on the depth image of the image to obtain a segmented image of the map elements in the depth map; and converting a two-dimensional position of the segmented image in the depth map to three-dimensional positions of the map elements in the target scene according to a registration relationship between the laser point cloud and the image. The map element extraction method and device andthe server provided by the invention are used to solve the problem of low production efficiency of a high-precision map 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...
