Light source adaptive adjustment method based on image quality analysis

The invention discloses a light source self-adaptive adjustment method based on image quality analysis, which mainly aims at fabric surface defect detection equipment and solves the problem that the image acquisition quality is reduced and the later detection is influenced due to the change of the acquisition environment of a camera caused by factors such as fabric and printing and dyeing color differences. The light source adaptive adjustment method provided by the invention can be divided into two quality analysis modes based on a full-reference image and a non-reference image. In the full-reference mode, the image quality score is calculated by applying a proposed similarity index (SIM) to the collected image and the standard image, and in the non-reference mode, the collected image only needs to be directly sent to a corresponding algorithm; and then the optimal illumination intensity is obtained through a corresponding search algorithm. The light source self-adaption method comprises an image evaluation
