Image defogging method, image defogging device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses an image defogging method, an image defogging device, electronic equipment and a storage medium, which are used for improving the defogging precision of the image defogging device in the process of defogging a foggy image by the image defogging device so as to improve the definition of a finally obtained target defogged image. The method provided by the embodiment of the invention comprises the following steps: acquiring a foggy image; obtaining a first transmissivity image according to an atmospheric light value in the foggy image; according to the foggy image, obtaining a second transmissivity image through an image channel processing algorithm; and fusing the first transmissivity image and the second transmissivity image to obtain a target defogged image.

Description

technical field [0001] The invention relates to the application field of electronic equipment, in particular to an image defogging method, an image defogging device, electronic equipment and a storage medium. Background technique [0002] In the prior art, electronic devices usually use an image enhancement algorithm and a dark channel prior defogging method to perform defogging processing on a foggy image to obtain a defogged image. [0003] However, in the process of using the image enhancement method, the electronic device may cause the restored image, that is, the defogged image to lose part of the information. Although the electronic device enhances the contrast of the fogged image, the final defogged image may be There is a problem with distortion. In addition, in the process of using the dark channel prior defogging method for electronic equipment, although the defogging effect on the fogged image is relatively good, the final defogged image will also have a dark ove...

Problems solved by technology

[0003] However, in the process of using the image enhancement method, the electronic device may cause the restored image, that is, the defogged image to lose part of the information. Although the electronic device enhances the contrast of the fogged image, the final defogged image may be problem with distortion

In addition, in the process of using the dark channel prior defogging method for electronic equipment, although the defogging effect on the foggy image is relatively good, the final defogged image will also have a dark overall image, and even some areas (for example: The problem of scene invalidation in the image of the sky area)

As a result, the clarity of the defogged image obtained by the electronic device is poor
