The invention discloses a bone age prediction method, system and equipment based on a hand X-ray image and a medium, relates to bone age prediction in the field of artificial intelligence, and aims to solve the technical problem that multiple steps based on an ROI (Region of Interest) are not suitable for being realized by an automatic method in existing deep learning. The method comprises the steps of obtaining corresponding feature vectors through an image, key points and a center line, selecting first k closest feature vectors, and averaging according to ages corresponding to the feature vectors to obtain an initial value of iteration of the image; inputting the related data into a relative rank regression device, and outputting a relative rank by the relative rank regression device; and performing iterative calculation by adopting the initial value and the relative rank, and after iteration is stopped, outputting the absolute rank at the moment as the predicted age of the input image. The method overcomes
