Due to it is most of in current existing face recognition device using specialty be dual camera collection facial image, its
In camera be used to obtain the colour-video signal of high-fidelity, for showing video information, another is then lived using having
The infrared camera of detecting functions, this camera is by obtaining the infrared imaging that human body sends, but the image of generation
It is black and white, is not suitable for display.But can be increased using the dual camera collection facial image of specialty in said system
Equipment cost is added.
Meanwhile, also there is other face recognition devices using single camera in the prior art, when recognition of face is carried out,
One of which scheme be directly using display video information with camera carry out face collection, in order to increase video display picture
Whole structure, it is to carry out recognition of face by obtaining face color data in video display picture, and such case is obtained
Human face data identification when, the accuracy of recognition of face can be greatly reduced, while again inevitably to non-human
Colour picture face carries out erroneous judgement.
Another scheme is then in contrast, in order to improve the accuracy of recognition of face, while preventing from being shown using video
The picture of picture is identified, and uses infrared camera, but using caused by this camera as a result, coloured silk cannot be shown
The vision signal of color, causes system to realize that the color video of high-fidelity is communicated, or also need to set a camera in addition
To realize the function of above-mentioned color video communication.
The content of the invention
The purpose of this utility model is to overcome disadvantage mentioned above, there is provided a kind of recognition of face single camera collection imaging system
System, it is possible to achieve substantially reduce equipment cost again while the stability and reliability that ensure face recognition device.
