A face recognition device having anti-interference capability and guaranteeing comprehensive feature extraction

Abstract

The invention provides a face recognition device having anti-interference capability and guaranteeing comprehensive feature extraction. The face recognition device has a body, a pedal and an enclosuremechanism. The enclosure mechanism comprises a top plate, gauze, a plurality of lamp tubes, two supporting mechanisms and four baffle plates. Each supporting mechanism comprises a side plate, a firstmotor and two supporting assemblies; each supporting assembly comprises a driving unit, a telescopic rack, a hinge block and two connecting rods. A shooting mechanism comprises a shooting plate, a second motor, two lifting assemblies and a plurality of second cameras; each lifting assembly comprises a second driving shaft, a driving wheel, a pull wire, a lifting block and a guide unit. The face recognition device having anti-interference capability and guaranteeing comprehensive feature extraction has the following advantages: during identity authentication, an enclosed environment is formedvia the enclosure mechanism, so that the device is prevented from being influenced by external light during a face recognition process; the shooting mechanism can be used for compensation shooting forareas around a nose, so that complete face feature data can be extracted by the apparatus and the face recognition precision of the apparatus is further improved.

Description

technical field [0001] The invention relates to the field of face recognition equipment, in particular to a face recognition device capable of anti-interference and comprehensive feature extraction. 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 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 f...

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
