Problems solved by technology

[0004] During the research and practice of the prior art, the inventors of the present invention found that in the existing solution, due to the use of a single camera, the viewing angle range is limited, and only one angle of face pictures can be taken. Therefore, the identification The accuracy is low, and it also affects its anti-attack ability, and the security is low. For example, an outsider without access control can easily use the insider's photo to pass through the access control, etc.

Embodiment 1

[0030] This embodiment will be described from the perspective of a face recognition device, and the face recognition device may specifically be integrated into a control device, such as a terminal or a server.

[0031] A face recognition method, comprising: obtaining a plurality of face images of an object to be recognized from different perspectives; extracting face feature information from the plurality of face images of different perspectives respectively, and obtaining a face corresponding to the object to be recognized A feature information group: based on the face feature information group, the face of the object to be recognized is recognized to obtain a recognition result.

[0032] Such as Figure 1b As shown, the specific flow of the face recognition method can be as follows:

[0033] 101. Acquire multiple face images from different perspectives of an object to be identified.

[0034] For example, multiple camera devices may be used to acquire face images of the obj...

Embodiment 2

[0077] In this embodiment, the face recognition system specifically includes a face recognition device and a plurality of cameras, and the face recognition device is integrated into a control device as an example for description.

[0078] Such as figure 2 As shown, a face recognition method, the specific process can be as follows:

[0079] 201. Multiple cameras located in different directions respectively shoot the recognition object, and send the multiple captured pictures to the control device respectively.

[0080] Among them, according to different application scenarios, the number and installation positions of the multiple cameras can be different. For example, for the access control face recognition scene, the multiple cameras can be installed on the door frame or bracket of the access control entrance, left and right sides respectively. The position on the right side; for the face recognition scene of the gate, these multiple cameras can be installed on the left and r...

Embodiment 3

[0106] Same as Embodiment 2, in this embodiment, the face recognition system specifically includes a face recognition device and multiple cameras, and the face recognition device is specifically integrated in the control device as an example for description; The difference in Example 2 is that in this embodiment, a score fusion method is used to fuse and identify multiple facial feature information, which will be described in detail below.

[0107] Such as image 3 As shown, a face recognition method, the specific process can be as follows:

[0108] 301. Multiple cameras located in different orientations respectively shoot the recognition object, and send the multiple captured pictures to the control device respectively.

[0109] Wherein, according to different application scenarios, the number and installation positions of the multiple cameras may be different, for details, please refer to step 201 , which will not be repeated here.

[0110] 302. After receiving the picture...

Abstract

The embodiment of the invention discloses a face identification method, device and system. According to the embodiment of the invention, the face images of multiple different view angles of an object to be identified, the face feature information is extracted from the face images of multiple different view angles, a face feature information group corresponding to the object to be identified is obtained, then the face of the object to be identified is identified based on the face feature information group, and an identification result is obtained. According to the scheme, the accuracy and safety of identification can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a face recognition method, device and system. Background technique [0002] Face recognition, also known as portrait recognition or facial recognition, is a biometric technology for identification based on human facial feature information. It can collect images or video streams containing human faces through camera equipment, and automatically detect and track human faces in the images, and then perform a series of related technologies on the detected faces. [0003] In the prior art, a single camera is generally used to obtain an image containing a face to be recognized. For example, a camera can be placed above the access control gate, and the camera can be used to obtain the person's face including the person who needs to pass through the gate. Then, use the algorithm to detect the image to extract the feature vector of the face, and compare the extracted featu...
