Low-illumination image enhancement method, related equipment and readable storage medium

The invention discloses a low-illumination image enhancement method, related equipment and a readable storage medium. In the scheme, training is carried out in advance based on a training image pair comprising a training low-illumination image and a training normal-illumination image which are not completely paired in the same scene to obtain a decomposition model, after a to-be-enhanced low-illumination image is obtained, the low-illumination image is input into the decomposition model to obtain an illumination image, and finally, the illumination image is obtained. And obtaining an enhanced image by using the illumination image. The decomposition model is obtained by training based on the incompletely paired image pairs, and the image pairs are easy to obtain in quantity, so that the training effect of the decomposition model is better, and the obtained illumination image is more accurate, and therefore, a better enhancement effect can be achieved by utilizing the illumination image to enhance the low-illum
