Disclosed are a method and apparatus for detecting bone age, which relate to the technical field of machine learning. The method comprises: acquiring a bone age picture of a user to be tested, and using a positioning model to determine the position of each target epiphysis in the bone age picture; and with regard to each target epiphysis, determining a bone age score of the target epiphysis according to a feature of the target epiphysis and the position of the target epiphysis, and determining the bone age of the user to be tested according to bone age scores of the various target epiphyses. After the bone age picture of the user to be tested is acquired, each bone in the bone age picture is adjusted to a reference position, which specifically comprises: acquiring a coordinate of a preset reference point (401); using an adjustment model to determine a coordinate of a key point in the bone age picture, wherein the adjustment model is determined by means of training a deep residual network taking a plurality of bone age pictures with coordinates of key points premarked as training samples (402); according to the coordinate of the preset reference point and the coordinate of the key point, determining a correlation between the current position of each bone in the bone age picture and the reference position (403); and according to the correlation, adjusting each bone in the bone age picture to the reference position (404). Different epiphysis forms represent different bone age stages, and epiphysis forms at different positions also have certain differences; therefore, the position of the target epiphysis is automatically determined by means of the positioning model, and then the bone age score is determined in conjunction with the feature of the target epiphysis and the position of the target epiphysis, and the bone age of the user to be tested is determined according to the bone age scores rather than being manually and subjectively determined according to the bone age picture, thus both improving the precision of bone age detection, and improving the efficiency of the bone age detection.
