## Abstract

The present disclosure provides a processing method, a device and a storage medium for rear view image. The processing method includes following steps: obtaining an original rear view image; obtaining vehicle data to determine at least one basic curvature; obtaining driver information to determine at least one floating curvature; and processing the rear view image according to the at least one basic curvature and the at least one floating curvature. By performing these steps, the processing method can adjust display curvature of the rear view image according to specific driving scenario and user needs, thereby clearly and personalized displaying rear view image with suitable range and display scale on the display screen with limited area, to help the user clearly observe situations on the left, right and rear sides of the vehicle.
