摘要： Disclosed are a method for generating a high-precision road map, a high-precision road map generation device, equipment and a storage medium. The method includes: based on a constant temperature control system, collecting a plurality of road information to be processed by different sensors (S10), so that the different sensors can all operate at a suitable temperature and are not affected by the environment; performing feature extraction on the plurality of the road information to be processed, and obtaining road feature information (S20); and connecting a mileage meter by a vehicle controller area network port or a related domain controller to obtain mileage information of the vehicle and posture control information of the vehicle, and predicting the posture of the vehicle to provide auxiliary information for an inertial system, and finally generating a high-precision road map according to the road feature information, vehicle body posture control information of a vehicle and mileage information (S30).
