specific Embodiment

[0067] (1) Place the optical reflection device 3 before the position of the person to be collected. There is a certain angle between each optical reflection surface, and the range of the angle is between 100 degrees and 170 degrees. By properly adjusting the angle, each The optical reflection device 3 can reflect the face image of the person being collected from different angles of view;

[0068] (2) The camera 2 is opposite to the reflective surface of the above-mentioned optical reflector 3, and the installation height and shooting angle are properly adjusted so that the camera 2 will not be blocked by the person being photographed, and can simultaneously collect the images of the person being photographed appearing in each optical For the facial image in the reflector 3, for example, the camera 2 can be installed above the head of the person being photographed, and can be photographed obliquely downward toward the optical reflection device 3, or the camera 2 can be installed...

Abstract

The invention discloses a method and a device for recognizing faces through multi-angle imaging. The method comprises the steps that optical devices are installed by an included angle of 100 degrees-170 degrees according to preset position and range; cameras are placed at the opposite positions of the optical reflection devices so as to simultaneously collect the face images of a person to be shot appearing in each optical reflection device; multiple face images of the person to be shot forming at different angles are obtained; the face images of different angels are respectively sent to a face recognition module for classification and recognition; the recognition results of all the face images are screened, and the most dependable image is selected as the final face recognition result. According to the method, the optical reflection device is used for simultaneously capturing the face images of one person at different angles for recognizing the faces, effective capture of face images of multiple angles is beneficial for the system to get the optimal recognition result, and the system is difficult to be affected by the change of face gestures, so that the recognition efficiency and the adaptability are high.

Description

technical field [0001] The invention belongs to the technical fields of pattern recognition, image processing and computer vision, and in particular relates to a method and device for face recognition by taking images from multiple perspectives. Background technique [0002] Face recognition is a kind of biological feature recognition technology. Under ideal experimental conditions, face recognition has achieved good results, and the accuracy rate can reach more than 95%. However, in the actual application environment, the face recognition The attitude is uncertain, and it is difficult to ensure that the camera can capture the face image from the same angle every time, which leads to a sharp drop in the accuracy of face recognition. One solution is to use multiple cameras from different angles of view. imaging and identification. [0003] It is inconvenient to use multiple cameras at the same time, and the viewing angles of the cameras need to be adjusted separately. The ca...
