[0051] With reference to the drawings in the specification, the specific embodiments of the present invention are further described below.
[0052] The three-dimensional face recognition method based on the grid vertical and horizontal local binary mode of the present invention realizes the three-dimensional face recognition process through the Matlab R2013a programming tool in the Windows operating system. The experimental data comes from the FRGC v2.0 three-dimensional face database, which contains 4007 face models of 466 people used for testing. figure 1 It is the overall flow chart of the method of the present invention, and the specific steps are as follows:
[0053] Step 1: Extract the face area of interest from the input 3D face point cloud, which is the face area contained in a ball with the tip of the nose as the center of the sphere and a radius of 90mm;
[0054] Step 2: After smoothing and denoising the three-dimensional face point cloud extracted in step 1, the nose po...
