The invention discloses a human face living body detection method, which is applied to the field of artificial intelligence, and comprises the steps of obtaining an initial human face image and a human face image set corresponding to N illumination directions; obtaining N differential images according to the initial face image and the face image set; generating a normal graph and a reflectivity graph according to the N differential images and the N illumination directions; and determining a human face living body detection result according to the N difference images, the normal graph and the reflectivity graph. The invention further discloses a related device, equipment and a storage medium. Due to the fact that the three-dimensional geometrical information and the surface material information of the face image are considered at the same time, the authenticity of the face image can be recognized, and different face living body attack modes can be effectively resisted.
