Multifunctional attendance machine capable of automatically tracking human face

Abstract

The invention discloses a multifunctional attendance machine capable of automatically tracking a human face, which comprises an infrared detector, a rear video preprocessing module of the infrared detector, the video preprocessing module is connected with a main control chip, the main control chip is connected with a steering engine control module and a display screen, the steering engine control module controls a steering engine two-dimensional holder, the steering engine two-dimensional holder is connected with an automatic zoom camera, and the automatic zoom camera is connected with the display screen. The main control chip is connected with the USB transmission interface, the DVI video transmission interface, the air quality sensor and the loudspeaker, the steering engine two-dimensional holder is provided with the motor protection shell, and the video preprocessing module, the main control chip, the steering engine control module and the steering engine two-dimensional holder are all provided with the box protection shell. The working principle is simple, the automatic zooming camera is adopted, automatic zooming can be achieved, and skin details can be recognized; the two steering engines are adopted to form a two-axis platform, and the pitching angle and the azimuth angle of the automatic zoom camera are adjusted, so that a human face can be automatically tracked; and the trained improved convolutional neural network face recognition algorithm is utilized to realize a good tracking effect of monitoring the face.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a multifunctional attendance machine for automatically tracking faces. Background technique [0002] In recent years, face recognition attendance machines have achieved unprecedented development, and face recognition technology in various fields has been improved. We are in a situation of unprecedented change in a century. Under the epidemic situation, the body temperature of the staff at work has been required, and the integration of attendance machines and body temperature detection is required. At present, face recognition attendance machines are gradually moving towards a mobile, fully digital, and intelligent direction. However, it is not targeted enough to meet the needs of rapid identification of employees' facial features, which puts forward the demand for automatic face tracking. [0003] The company has high staff turnover and intensive staff, which has high r...
