Abstract: 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, 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; 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.

Abstract: Disclosed are a method, an apparatus and a device for generating a road data evaluation report, and a computer-readable storage medium. The method includes: obtaining road data to be processed and road data to be evaluated; desensitizing the road data to be processed to obtain target road data; determining truth road data according to the target road data; and generating a road data evaluation report according to the truth road data and the road data to be evaluated.

Abstract: Disclosed are a vehicle positioning method based on environment matching, a vehicle positioning device based on environment matching, a vehicle and a storage medium. The method includes: obtaining current environment data and a current road image of a location of a vehicle to be located; searching for an environmental impact road image set matching with the current environment data; matching the current road image with an environmental impact road image in the environmental impact road image set respectively to obtain a target environmental impact road image matching with the current road image; and determining current location information of the vehicle to be located based on the target environmental impact road image.

Abstract: Provided is a video image processing method, apparatus, and device, and a storage medium. The method includes: obtaining a first target-frame video image, the first target-frame video image being one of to-be-processed multi-frame video images; performing target detection on the first target-frame video image to determine at least one target object in the first target-frame video image; determining at least one first to-be-processed target object of the at least one target object based on a predetermined classification rule of a to-be-processed target object; and replacing, in the first target-frame video image, the at least one first to-be-processed target object with a predetermined target substitute to obtain a second target-frame video image. Data volume of the predetermined target substitute is smaller than date volume of the at least one first to-be-processed target object. Data volume of a video is reduced without affecting an actual output effect using the method.

Abstract: The present invention discloses a method of forming a polygon-sectional rodlike ingot having an orientation marker or rounded corners, a rodlike ingot and a sheet substrate so formed. The method comprises: selecting one of sides of the polygon-sectional rodlike ingot that is parallel to an axial direction thereof as a first feature of a surface orientation marker; forming a minisize notch, which is parallel to an edge, in the one of sides selected as the first feature in the axial direction of the rodlike ingot, as a second feature of the orientation marker; and processing the rodlike ingot to form rounded corners. The sheet substrate is obtained by cutting the rodlike ingot.
