The invention discloses a method, device, equipment and storage medium for generating a road high-precision map. The method includes: collecting a plurality of road information to be processed through different sensors based on a constant temperature control system, so that different sensors can be processed at a suitable temperature. Run without being affected by the environment, and then perform feature extraction on multiple road information to be processed to obtain road feature information, and then connect the odometer through the vehicle controller LAN port or related domain controller to obtain vehicle mileage information and vehicle attitude control information, and predict the attitude of the vehicle, provide auxiliary information for the inertial system, and finally generate a high-precision road map based on road feature information, vehicle body attitude control information, and mileage information. In the present invention, the road features can be stored and transferred through the hard disk. Offline mapping can also be collected and drawn through the online channel, so as to update the background map in real time, so that the self-driving vehicle can be accurately positioned.
Description
technical field [0001] The present invention relates to the technical field of vehicles, in particular to a method, device, equipment and storage medium for generating a high-precision road map. Background technique [0002] With the development and technological iteration of autonomous driving, the mass production of autonomous vehicles is getting closer. In order for the automatic driving system to better understand its own posture during automatic operation, and perform precise behavior planning and body control, high-precision positioning is very important. There are currently two ways to achieve high-precision positioning recognized by the industry. One is a high-precision positioning system based on satellite positioning and inertial navigation systems. This positioning system relies on fixed-frequency multi-satellite communication to achieve positioning. When satellite communication is not available in the area, the inertial navigation system is used for position est...
