Embodiment Construction
[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0024] A kind of three-dimensional face recognition method that is used for safe of the present invention comprises the following steps:
[0025] (1) Adjust the relative positions of the left and right cameras and the face to complete the collection of two-dimensional images of the face;
[0026] (2) utilize active shape model to carry out feature point automatic location to the two-dimensional image that step (1) collects;
[0027] (3) Combining the internal and external parameters of the camera to obtain the three-dimensional coordinates of the key feature points of the face;
[0028] (4) Utilize the three-dimensional coordinates of step (3) to calculate the feature point distance matrix, and extract the geometric features of the three-dimensio...
