The invention provides a non-reference image quality evaluation method and device and electronic equipment, and the method comprises the steps: inputting to-be-evaluated non-reference image data and a preset parameter text into a pre-trained multi-modal quality evaluation model, outputting an overall quality score corresponding to the non-reference image data and quality scores of multiple dimensions; the quality scores of the multiple dimensions comprise a brightness score, a contrast score, a definition score, a color score and a noise score; and according to a preset weight coefficient, carrying out weighted calculation on the quality score of each dimension and the overall quality score to obtain quality ultimate scores of multiple dimensions corresponding to the non-reference image data. In the mode, through the multi-modal quality evaluation model, the quality ultimate scores of multiple dimensions corresponding to the non-reference image data can be output, and fine granularity evaluation is performed
