Abstract

The invention discloses a brightness correction method, system and equipment and a computer readable storage medium. The method comprises the steps of obtaining a detection shooting image obtained after a preset shooting equipment shoots an original detection image; determining shooting brightness attenuation information of a preset shooting equipment based on the detected brightness of the shot image; obtaining a projection shooting picture obtained after the preset shooting equipment shoots the original projection picture, wherein the original projection picture is a picture obtained after the target projection equipment projects the original detection picture; performing brightness compensation on the projection shooting image based on the shooting brightness attenuation information toobtain a projection compensation image; and determining brightness correction information of the target projection equipment based on the brightness of the projection compensation image and the original detection image, and performing brightness correction on the target projection equipment based on the brightness correction information. According to the invention, the target of performing brightness correction on the target projection equipment by means of the shot picture is realized, and the brightness correction efficiency is high. The brightness correction system and equipment and the computer readable storage medium provided by the invention also solve the corresponding technical problems.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a brightness correction method, system, device, and computer-readable storage medium. Background technique [0002] In the application process of projection equipment, due to the optical structure of projection, near light is bright and far is dark, so that the brightness of the projected picture is the brightest in the middle and lower part, and the surrounding area is dark, which affects the quality of light, especially the effect of short-focus projection. Therefore, it is necessary to The projection device performs brightness correction. However, in the existing brightness correction method, the projection image of the projection device is directly operated, and the operation is complicated and the efficiency is low. [0003] To sum up, how to improve the brightness correction efficiency of a projection device is an urgent problem to be solved by ...
