Description

technical field [0001] The invention relates to a face recognition system, in particular to a three-dimensional face reconstruction system on a rotating platform. Used in the field of biometric identification. Background technique [0002] Most of the usual face recognition systems are researched on two-dimensional photos or dynamic video sequences. However, there are serious obstacles in the recognition based on two-dimensional photos. The main reason for these problems is that the human face itself is three-dimensional, and the photo is the result of the plane projection of the three-dimensional face, and some important information must be lost in the process. The biggest difference between using 3D recognition and traditional methods is that face information can be better represented and stored, such as the depth information of face feature points and the topology between points, etc. Since the 3D face model has the characteristics of illumination independence and pose ...

Problems solved by technology

[0003] Through literature search, it is found that the head and face color 3D scanner (Head & Face Color 3D Scanner, model 3030RGB) produced by American Cyberware Company uses a single-chip microcomputer to control a stepping motor to continuously rotate the rotating arm, and a laser generator is installed on the rotating arm And the camera, using the laser generator to emit low-intensity laser as a scanning line, projected onto the face, the camera obtains the face image with the scanning line, and sends it to the graphics workstation for image processing. Due to the harmfulness of the laser to the human body, especially for The damage to human eyes and the use of workstations make the system expensive, which limits its application in 3D face modeling
