Problems solved by technology

However, since monocular vision often requires scanning of the projected beam or comparison with reference textures, its ease of use and imaging speed are flawed.

Embodiment Construction

[0021] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0022] The face recognition solution of the present invention is based on the binocular visual recognition technology capable of real-time three-dimensional measurement of object surfaces. Binocular visual recognition technology directly simulates the way human eyes process scenes. According to the principle of triangulation, two cameras in different positions are used to shoot the same scene. Go to the picture to find the same target that ...

Abstract

The invention discloses a face identification equipment and method. The face identification equipment is characterized in that a first projecting device is used for projecting a discrete light beam toa photographing region, a second projecting device not operating at the same time as the first projecting device is used for projecting substantially-uniform light to the photographing region, firstand second imaging units having the predetermined relative position relationship are used for photographing the photographing region to respectively acquire first and second two-dimensional images under irradiation of discrete spots, and a processor is used for acquiring the depth map information of a face in the photographing region based on the first and second two-dimensional images, acquiringthe outline information of the face based on the two-dimensional images photographed under the projected uniform light and determining whether the face of the photographing region is the same as a stored target face according to the depth map information and the outline information. The equipment is advantaged in that the information required for identifying the to-be-detected face in various application scenes can be rapidly and accurately acquired through photographing two-dimensional and three-dimensional image materials frame by frame.

Description

technical field [0001] The invention relates to the field of image measurement and processing, in particular to a device and method for face recognition. Background technique [0002] Face detection and recognition have been widely used in identity authentication in various scenarios. For example, using your face to unlock your phone or make payments. The traditional image capture method can only obtain the two-dimensional information of the face, but cannot obtain the spatial depth information. Therefore, criminals can use photos and videos to deceive the computer into successful recognition. This greatly limits the feasibility and reliability of face recognition authentication. By introducing the measurement and detection of three-dimensional face information, the application range of face recognition can be greatly improved. [0003] Three-dimensional information can also be called depth information or depth of field information. At present, the three-dimensional meas...
