Summary:The invention is applied to the field of artificial intelligence, relates to the field of block chains, and discloses an image quality detection method and device, equipment and a medium, and the method comprises the steps: obtaining a to-be-processed image, and employing a character positioning model to position characters in the to-be-processed image, so as to determine a character region in the to-be-processed image, performing Sobel operator convolution processing on a character region in a to-be-processed image to obtain a target convolution matrix of the character region, and obtaining region information of the character region according to pixel values and distribution intervals of pixels in the target convolution matrix, and finally, determining a quality detection result of the to-be-processed image according to the region information of the character region and a preset quality condition. According to the invention, the interference of image background information can be reduced, the precision of a
