摘要： A method for face authentication is proposed. The method includes at least one face detection step including determining at least one first image by using at least one camera, determining at least one material property from a second image, where the second image is recorded while projecting at least one illumination pattern including a plurality of illumination features on the scene, and at least one authentication step including authenticating the detected face by using the face detection and the material property.

摘要： Disclosed herein is a method for face authentication. The method includes the following steps:



a) at least one face detection step including determining at least one first image by using at least one camera;
b) at least one skin detection step including projecting at least one illumination pattern including a plurality of illumination features on the scene by using at least one illumination unit, determining at least one second image using the at least one camera, and determining a first beam profile information;
c) at least one 3D detection step including determining a second beam profile information of at least four of the reflection features located inside the image region of the second image corresponding to the image region of the first image; and
d) at least one authentication step including authenticating the detected face by using at least one authentication unit.
