Anti-interference high-precision face recognition device

Abstract

The invention relates to an anti-interference high-precision face recognition device. The device comprises a shell, a pressing plate and a sealing mechanism, the sealing mechanism comprises a ceiling,a gauze, a plurality of illuminating lamps, two supporting mechanisms and four shielding plates, and the supporting mechanism comprises a side plate, a first motor and two supporting assemblies. Thesupporting assembly comprises a driving unit, a telescopic frame, a connecting block and two connecting rods, a shooting mechanism comprises a flat plate, a second motor, two lifting assemblies and aplurality of second cameras, and each lifting assembly comprises a rotating shaft, a rotating wheel, a connecting wire, a lifting block and a guide unit. According to the anti-interference high-precision face recognition device, a closed environment is formed through a closed mechanism during identity authentication, so that the device is prevented from being interfered by the external light during the face recognition process. In addition, the compensation shooting is carried out at the periphery of a nose through the shooting mechanism, the device can extract the complete face feature data conveniently, and the face recognition precision of the device is further improved.

Description

technical field [0001] The invention relates to the field of face recognition equipment, in particular to an anti-jamming high-precision face recognition device. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or video camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. [0003] It can be seen from the technical principle of face recognition that when the existing face recognition is used for identity verification, it mainly relies on the camera on the device to collect images, and compares the feature data extracted from the images to achieve the function of identity authentication. The surface of the human face is uneven, especially at th...

Problems solved by technology

[0003] It can be seen from the technical principle of face recognition that when the existing face recognition is used for identity verification, it mainly relies on the camera on the device to collect images, and compares the feature data extracted from the images to achieve the function of identity authentication. The surface of the human face is uneven, especially at the nose position. Because the nose is protruding, the nose will block the nearby faces when the camera is shooting, resulting in incomplete images collected by the camera, which is not conducive to the equipment to extract complete feature data extraction. , which reduces the recognition accuracy of the device. Not only that, the camera is easily affected by the light of the external environment when shooting. When the light around the device is too bright or too dark, it will interfere with the formation of the image and change the feature data extracted from the face. , leading to a reduction in the recognition accuracy of existing face recognition equipment
