Personnel attendance checking method and system

Abstract

The invention discloses a personnel attendance checking method and system, and the method comprises the steps: enabling a plurality of cameras to collect images of a to-be-checked area at the same time, and transmitting the images to an intelligent visual analyzer, wherein the plurality of cameras are arranged at different positions so as to cover all the to-be-checked area; detecting inclined angles between a human face and the cameras for the images, and for the human face images, collected by different cameras, of an intersection area, adopting an image with the smaller inclined angle between the human face and the cameras; performing feature extraction and matching recognition of each face to obtain a recognition result ID; carrying out recognition result denoising through a clusteringalgorithm, and outputting a final recognition result. According to the scheme, on the basis that a face recognition algorithm is not changed, the plurality of cameras are arranged through the array technology, and the full coverage of the whole space is achieved. Meanwhile, the recognition result is optimized through the clustering optimization technology, the error rate is greatly reduced, and aperson can output an accurate attendance result only through a few seconds on a video.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and system for personnel attendance checking. Background technique [0002] Face attendance is a machine that uses face attendance. It uses face recognition technology to identify people using differences in faces. Using face recognition to identify people in classrooms and meetings is very efficient and has broad application prospects. Classrooms and conferences often have a large space and many people. However, due to the size of the camera CMOS and the wide-angle limitation of the lens, the lens cannot cover all the areas to be attended. The existing solution uses single-camera polling technology to divide a standard space into N areas. By turning the camera, each area is polled for a few seconds, and the attendance of the entire space personnel can be completed after a certain period of time. However, if the person walks around during the camera movement t...

AI Technical Summary

Problems solved by technology

However, if the person walks around during the camera movement time, it may cause the person not to be captured by the camera in any area. If the person is not recognized during that period of time covered by the camera, it will be regarded as absent. Cause wrong attendance results
