Face recognition intelligent monitoring system

Abstract

The invention discloses a face recognition intelligent monitoring system which comprises an image acquisition and display device, a core processing device, a communication device and a power supply part. The image acquisition and display device comprises a near infrared camera, a visible light camera and an LED display, and a complex programmable logic device (CPLD) connected with the near infrared camera and the visible light camera. The CPLD is connected with an LED light board through a multi-mode LED controller. The core processing device is a multimedia processing chip OMAP3530 connected with the image acquisition and display device. The communication device comprises a network port, a serial port, an SD card and a touch screen. The power supply part provides power support for the device. The face recognition intelligent monitoring system can automatically recognize a human face without being limited by light conditions, and performs analysis and comparison, and provides technical support for security work.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to an intelligent monitoring system for face recognition. Background technique [0002] The advancement of science and technology and the development of the economy have brought about the improvement of the living standards of the whole society, but at the same time, various crimes that endanger social stability and the safety of people's lives and property have emerged in an endless stream, which poses new challenges to the existing security system. Therefore, it has become an important task of security work to prevent and stop crimes by using high-tech means to ensure the normal operation of various industries, national key departments and important institutions. [0003] With the advancement of social economy, the traditional monitoring management mode is facing the challenge of reform. On the one hand, the form of security protection is becoming increasingly seve...

Problems solved by technology

[0005] However, most of the existing face recognition technology applications are based on visible light recognition, and its recognition accuracy is greatly affected by changes in ambient light intensity.

In order to improve the accuracy of face recognition under changing lighting conditions, some new visual recognition methods have been introduced into the field of face recognition, such as 3D vision, infrared thermal imaging technology, etc. These methods have the disadvantage of high hardware cost and are difficult to be widely used.
