Embodiment 1

[0044] Embodiment 1 Face recognition monitoring system based on spectrum and multi-band fusion

[0045] refer to figure 1 , a kind of face recognition monitoring system based on spectrum and multi-band fusion provided by the present invention, this system comprises spectrum camera 1, supplementary light source (broadband white light source, can be bromine tungsten lamp), human face spectrum image acquisition module 2 , face spectrum image data preprocessing module 3, face spectrum image database 4, face spectrum image recognition module 5;

[0046] Wherein, the spectral camera includes an optical lens and a silicon-based detector. The optical lens can automatically adjust the focal length according to the target distance in the monitoring area. The device includes a photoelectric conversion substrate 101 and a filter film 102 arranged on the photoelectric conversion substrate. The film thickness of the filter film 102 is 10 μm, its size is 4mm×4mm, and the data acquisition ti...

Embodiment 2

[0061] Embodiment 2 A recognition method of a face recognition monitoring system based on spectrum and multi-band fusion

[0062] Such as Figure 6 As shown, a kind of recognition method of the face recognition monitoring system based on spectrum and multi-band fusion provided by the present invention comprises the following steps:

[0063] Step S1: 1 person to be tested enters the monitoring area, the Spectrum camera locks the face target, and the optical lens automatically focuses to make the face of the tester clearly imaged. When there are multiple people to be tested, the Spectrum camera locks multiple face targets at the same time, The optical lens automatically focuses, so that the faces of multiple inspectors can be clearly imaged. When the light is insufficient and the image cannot be clearly imaged, the supplementary light source is turned on;

[0064] Step S2: Start the silicon-based detector and face spectrum image acquisition module, the visible spectrum sensing ...

Abstract

The invention relates to a face recognition monitoring system and recognition method based on spectrum and multiband fusion. The system comprises a spectrum camera, a face spectrum image acquisition module, a face spectrum image data preprocessing module, a face spectrum image database and a face spectrum image recognition module. The spectrum camera comprises an optical lens and a silicon-based detector. The silicon-based detector comprises a photoelectric conversion substrate and a filtering film arranged on the photoelectric conversion substrate. The filtering film comprises N units; each unit comprises three areas, specifically a visible spectrum sensing area, a near infrared spectrum image sensing area and an RGGB image acquisition area; and the N units cover all pixel points on the photoelectric conversion substrate. According to the system, the purpose of obtaining reflection multispectral data, near-infrared band face images and RGGB face images of the face in the visible-near-infrared band can be achieved through one camera, the cost of the monitoring system is greatly reduced, and more accurate recognition of the face is achieved.

Description

technical field [0001] The invention belongs to the field of optics, relates to the related technical fields of face recognition and monitoring, in particular to a face recognition monitoring system and recognition method based on spectrum and multi-band fusion. Background technique [0002] Video surveillance has always played an important role in the security field. With the development of science and technology, face recognition technology has entered the monitoring field with the most friendly biometric authentication technology, which dynamically captures facial images through cameras, and then compares and recognizes them. The core of face recognition technology is to use the orientation relationship of various organs and characteristic parts of the face or the skeleton characteristics of human body posture to form recognition parameters, which are recognized and calculated with the parameters in the template database, and finally give a judgment, for example: CN 11079...
