[0065] figure 1 It is a block diagram of the off-line multi-face recognition system of the present invention.
[0066] see figure 1 , an offline multi-face recognition method based on an Android device, first configure an acquisition unit, an interface module, a tool module, a business module, a face detection module, a living body detection module, a feature extraction module and a face recognition module, and the business module Store human face characteristic data; The acquisition unit includes at least one infrared LED fill light and an infrared camera provided with an infrared filter;
[0067] The method comprises the steps of:
[0068] Step S01:
[0069] The acquisition unit dynamically controls the PWM wave (Pulse Width Modulation Wave), changes the intensity of the infrared LED supplementary light, collects face images under different light intensities, extracts the face area from the face image through the MTCNN network model, and then passes The dlib library perf...
