Abstract

The invention discloses a three-camera face recognition device and method based on an FPGA. The device comprises a three-camera unit, a camera installation disc, an angle adjustment device, an FPGA unit, a control unit, a power unit, a storage unit, and a communication unit. The method comprsies the steps of collecting images through a first visible light camera, a second close-range infrared camera and a third long-range infrared camera; s2, outputting an image P1 according to the image shot in the step S1; s3, preprocessing the image P1, and outputting a target image P2; s4, performing feature fusion and recognition on the image P2 to obtain a recognition result; s5, outputting and recognizing the recognition result. The face recognition method has the advantages of being high in robustness, accurate in recognition, long in test distance and capable of recognizing dark light, and the problems that an existing face recognition camera is low in recognition rate, high in system complexity and low in recognition speed are solved.

Description

technical field [0001] The present invention relates to the technical field of cameras, in particular to an FPGA-based three-camera face recognition device and method. 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] Existing face recognition equipment generally adopts dual cameras: one is a visible light camera and the other is an infrared camera. Infrared cameras are hardly affected by lighting, so infrared images are used for actual recognition. What is displayed on the screen of the face recognition device is not an infrared image, but a visible light image, because the ...
