Abstract

The invention provides a road network map generating method, a road network map generating system, road network map generating equipment and a storage medium. The method comprises the following stepsof obtaining collection data of a laser radar on a mobile collecting device to obtain multiframe point cloud data; obtaining collection data of an inertial measurement unit on the mobile collecting device corresponding to each frame, wherein the collection data of the inertial measurement unit includes the linear velocity and the angular velocity of the mobile collecting device at the front frame;generating a high-precision map according to the point cloud data and the collection data of the inertial measurement unit; extracting a road network map from the high-precision map. The invention provides the technical scheme for generating a road network map; the road network map is automatically extracted and generated; the problems of low precision and low efficiency of a manual extraction method in the prior art is solved; the technical scheme can be used for road network map extraction in a specific open industrial region, and has the characteristics of high automation, high robustnessand high precision.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a road network map generation method, system, device and storage medium suitable for automatic driving. Background technique [0002] With the continuous evolution of autonomous driving technology, the requirements for high-precision maps and road network maps are getting higher and higher, and autonomous driving scenarios above the L4 level require centimeter-level maps. High-precision map refers to a machine-oriented high-precision map for self-driving cars. It not only has high-precision coordinates, but also has accurate road shape, and contains the slope, curvature, heading, elevation and roll of each lane. data. The high-precision map not only describes the road, but also depicts how many lanes there are on a road, which will truly reflect the actual style of the road. The road network map is the information extraction of high-precision maps, which is us...
