Title:
COLORING METHOD AND APPARATUS FOR THREE-DIMENSIONAL ROAD SURFACE, AND STORAGE MEDIUM, ELECTRONIC DEVICE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/040500
Kind Code:
A1
Abstract:
Disclosed in the present application are a coloring method and apparatus for a three-dimensional road surface, and a storage medium, an electronic device and a vehicle, which can solve the problem of the generation of a road edge line being time-consuming and inaccurate. The method comprises: performing a restoration operation on a three-dimensional road surface according to a preset distance, and curved-surface parameters of the three-dimensional road surface, so as to generate a first three-dimensional road surface point cloud; according to the pose of each frame of road image in the first three-dimensional road surface point cloud, determining a second three-dimensional road surface point cloud corresponding to the road image, wherein the second three-dimensional road surface point cloud comprises three-dimensional road surface points, the distances from which to the pose of the road image are less than or equal to the preset spacing, in the first three-dimensional road surface point cloud; projecting the second three-dimensional road surface point cloud to the corresponding road image, so as to obtain a projection point cloud in the road image; and coloring, by means of a target color, target three-dimensional road surface points, which correspond to target projection points, in the first three-dimensional road surface point cloud, so as to display a road edge of the three-dimensional road surface in a highlighted manner, wherein the target projection points comprise projection points, which are located in a target area, in a projection point cloud of each frame of road image.
