Abstract

The application discloses a method and device for testing the accuracy of high precision maps. One embodiment of the method comprises following steps: restoring a road network map from a high precision map; obtaining a 3D point cloud road image labeled actual coordinates of map elements; fitting the 3D point cloud road image to the road network map to obtain fitted road network map of the 3D point cloud road image; calculating the difference between the actual coordinates of the 3D point cloud road image in the fitted road network map of the 3D point cloud road image and the map coordinates of the road network map; responding when the different is less or equal to a preset threshold to determine that the high precision map is accurate. The embodiment realizes verification of coordinates of high precision maps and increases the efficiency of verifying whether there is difference between the road information of high precision maps and actual roads; the verification error due to artificial verification is avoided; the accuracy of high precision map verification is increased.

Description

technical field [0001] The present application relates to the technical field of testing, in particular to the technical field of map testing, and in particular to a method and device for testing the accuracy of high-precision maps. Background technique [0002] High-precision maps are used for self-driving cars. It is necessary to determine whether road coordinates, road lights, identification characters, coordinates, digital information, etc. are different from the actual road. [0003] At present, when determining the difference between the high-precision map and the actual road, it is usually checked manually and the map data is restored to the road network for inspection. [0004] However, the current method for determining the difference between the high-precision map and the actual road cannot verify the coordinates of the high-precision map, and the efficiency of verifying whether there is a difference between the road information of the high-precision map and the ac...
