Recovery method and device based on series model

The invention provides a recovery method and device based on a series model, electronic equipment and a storage medium, and relates to the technical field of computers. The method comprises the steps that a low-quality image is acquired, the low-quality image is input into a pre-trained image quality evaluation large language model to acquire degradation information and semantic information corresponding to the low-quality image, and the semantic information comprises detailed semantic information and brief semantic information; calling a pre-trained low-frequency restoration model and a pre-trained high-frequency restoration model, and inputting the low-quality image, the degradation information and the brief semantic information into the low-frequency restoration model to obtain a corresponding low-frequency restoration image; and inputting the low-frequency restored image and the detailed semantic information into a high-frequency restored model, and determining a corresponding target restored image.
