Dynamic AE control method for fine-grained scene perception

The invention discloses a dynamic AE control method for fine-grained scene perception, and is applied to the technical field of image processing. Comprising the following steps: S1, carrying out dynamic scene detection on a detected picture; s2, if the camera in the detected picture and the object in the picture move, performing scene perception processing on the detected picture; if the camera in the detected picture and the object in the picture do not move, entering S5; s3, obtaining object features, brightness and scenes of all areas of the detected picture according to scene perception processing; s4, adaptively distributing exposure weight of each block according to the obtained object characteristics, brightness and scene of each area, and performing perception AE stability control; and S5, performing AE general control on the detected picture, and ending the dynamic exposure adjustment of the detected picture. According to the invention, appropriate exposure brightness can be calculated in scenes with
