Antiaging assessment method and device for facial rejuvenation

An antiaging assessment device for facial rejuvenation, the antiaging assessment device comprising:

• a facial image input module comprising a facial image photographing unit and a positioning mechanism, wherein the facial image photographing unit acquires an under-test facial image, and the positioning mechanism stabilizes a head of a patient and positions the facial image photographing unit, so that the under-test facial image is acquired by the facial image photographing unit stably;
• an artificial intelligence facial recognition module connected with the facial image input module, and comprising a facial key point detection unit and a facial feature description unit, wherein the artificial intelligence facial recognition module recognizes plural facial key points in the under-test facial image, so that plural facial features are obtained, wherein a spatial relationship between at least two facial key points of the plural facial key points is defined as at least one facial feature;
• a facial feature reference/historical database providing at least one reference feature;
• a facial surface rejuvenation measurement unit connected with the artificial intelligence facial recognition module and the facial feature reference/historical database, wherein after the facial surface rejuvenation measurement unit receives the at least one reference feature, the facial surface rejuvenation measurement unit performs a feature change comparison between the at least one reference feature and the at least one facial feature, so that at least one feature change value between the at least one reference feature and the at least one facial feature is obtained;
• and
• a facial rejuvenation score index establishment and assessment unit connected with the facial surface rejuvenation measurement unit, and containing a facial rejuvenation score index data table, wherein the facial rejuvenation score index establishment and assessment unit acquires a corresponding facial rejuvenation score index from the facial rejuvenation score index data table according to the at least one feature change value,
• wherein in the facial rejuvenation score index data table, each of the at least one facial feature is related to plural feature change value ranges, and each of the plural feature change value ranges is related to the corresponding facial rejuvenation score index, wherein when a specified feature change value lies in a specified feature change value range of the plural feature change value ranges, the corresponding facial rejuvenation score index is obtained.
