Provided are a 3D face identity authentication method and apparatus. The method comprises the following steps: obtaining a depth image and a two-dimensional image which include a target face; performing registration on the depth image and a reference face 3D texture image, so as to obtain pose information of the target face; performing alignment on the two-dimensional image according to the pose information, so as to obtain a target face two-dimensional image; extracting feature information in the target face two-dimensional image; performing similarity comparison on the feature information in the target face two-dimensional image and feature information in a reference face two-dimensional image. The method combines 3D information to obtain a pose of a target face and performs alignment according to the pose, thereby ensuring to a greater extent the consistency of a current target face two-dimensional image and a reference face two-dimensional image in order to increase recognition accuracy. The method also comprises steps of eye line of sight detection, liveness detection and data updating in order to improve user examination, reduce false recognition rates and tackle problems such as facial changes.
