Abstract

The present disclosure relates to the technical field of automatic driving, and provides a map acquisition method, device, electronic equipment, and storage medium. The method is applied to automatic driving equipment, that is, unmanned equipment or unmanned vehicles, including: establishing a long-term connection with the first high-precision map platform, and sending the location information of the vehicle to the first high-precision map platform, the first high-precision map platform The fine map platform includes a first high-precision map; when it is determined based on the position information that the vehicle is in the first area covered by the first high-precision map, receive the first high-precision map sent by the first high-precision map platform; When the location information determines that the vehicle is about to leave the first area, search for at least one second high-precision map platform, at least one second high-precision map platform includes a second high-precision map, and the second high-precision map includes The second area, and the first distance between the second area and the first area is less than or equal to the preset distance. The present disclosure improves the flexibility of map acquisition.

Description

technical field [0001] The present disclosure relates to the technical field of automatic driving, and in particular to a map acquisition method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] Autonomous driving is the development trend of smart transportation in the future. Traditional electronic navigation maps can no longer meet the needs of autonomous driving. High-precision maps are the key infrastructure for autonomous vehicles. Therefore, they are also called autonomous driving maps. The high-precision navigation map based on laser point cloud technology can provide centimeter-level road network information through scanning, analysis and processing, and 3D reconstruction of the real environment, and accurately display scenes with dense traffic elements such as lane-level, complex intersections, and viaducts. Driving provides strong infrastructure protection. However, in the prior art, automatic driving equipment need...
