Abstract

The application provides an image processing method, device and equipment, the method comprising: determining a first scale value of a first grid based on a target panoramic image, the first scale value being a scale value of a shadow area of a first image region to a total area of the first image region; mapping a plurality of vertices of a vehicle to a plurality of ground projection points based on a candidate light direction, the plurality of ground projection points forming a plurality of shadow planes; determining a second scale value of the first grid based on the plurality of shadow planes, the second scale value being a scale value of a reference sub-grid to a total number of a plurality of sub-grids, the reference sub-grid being a sub-grid having an overlapping area with any shadow plane; selecting a candidate light direction with a minimum difference value as a target light direction based on a difference between the first scale value and a second scale value corresponding to each candidate light direction; and performing brightness compensation on the first image region based on a target brightness compensation value corresponding to the target light direction. Through the technical scheme, the image display effect can be improved.
