Quality evaluation model training method and device and electronic equipment

The invention relates to a quality evaluation model training method and device and electronic equipment, and the method comprises the steps: obtaining a plurality of face image sets and image features of face images in the face image sets; multiple face images in the face image set belong to the same object; different face image sets correspond to different objects; for each candidate face image, determining same-object feature similarity distribution and different-object feature similarity distribution of the candidate face image according to image features of the candidate face image, image features of a first face image in the same face image set and image features of a second face image in the different face image set; according to the above two distributions, the image quality scores of the candidate face images are determined, and then the initial quality evaluation model is trained, so that manual image quality score labeling of the face images is avoided, the image quality scores are determined in com
