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.
