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.
