Description

Human face recognition module

【Technical field】A kind of human face recognition module, it is espespecially a kind of human face recognition and video signal function are integrated into one face Recognize module.

【Background technology】

Existing camera device on the market is mainly used in shooting photo or records short-movie and carry out networking video signal, and can not expire completely The sufficient increasing human-computer interaction requirement of people, user needs the man-machine interaction experience of simpler more convenient and quicker, therefore should The personage of skill develops human-computer interaction interface, the existing camera having because being confined to hardware and images capture technique, and The cost of camera mechanism great number, therefore can not be widely used in display device, also can be with general without decree camera And interactive application is in the work of face's characteristic identification.

Traditional face detection is based primarily upon the face recognition of visible images, but this mode has and is difficult to overcome Defect, when ambient lighting changes, recognition effect can drastically decline, it is impossible to the need for meeting real system, for example, clap According to when run into sidelight when " negative and positive face " black and white phenomenon for occurring, it is possible to can not correctly recognize.

Another person, colour phhotograpy camera lens is also easily because in the case that light refraction reflection source is not enough, make the face of face Characteristic produces shade and causes the problems such as characteristic is not obvious, in turn results in the problems such as can not judging and judge by accident.

Furthermore, if using black and white camera lens camera lens instead, when needing to use video signal to work, then achromatization is presented quite not convenient.

Therefore how improving human face recognition precision and how having video signal function concurrently is then the target that this primarily improves as dealer.

【The content of the invention】

Therefore, be the shortcoming that solves above-mentioned known technology, the main purpose of the present invention there is provided one kind by human face recognition and video signal Function is integrated into one human face recognition module.

For up to above-mentioned purpose, the present invention provides a kind of human face recognition module, comprising：

One substrate, with one first plane, first plane is provided with one first lens group, one second lens group, an infrared ray LED groups and an image processor, and be connected respectively with the electrical property of substrate, the infrared LEDs group has one first infrared LEDs And one second infrared LEDs and be mutually adjacent to the foregoing second lens group left and right sides.

Main pass through sets one first lens group and one second lens group and an image processor, is traditional respectively RGB cameras, infrared camera and infrared LEDs.

First lens group（RGB cameras）Charge capture 2D picture information, it can be ensured that RGB image quality, it is full Sufficient client's video signal camera function, the second lens group（Infrared pick-up head）And infrared LEDs are combined, Image Performance is preferable for the part of face recognition, more favourable recognition of face；The power of infrared LEDs adopts dynamic detection Mode, illuminated object is nearer, and power is lower, and illuminated object is more remote, then power is higher, the advantage of lower cost of heat sink conception；Thoroughly Crossing the present invention can be lifted outside human face recognition precision and can have colour video information image transmission concurrently.

【Embodiment】

The above-mentioned purpose and its structure of the present invention and characteristic functionally, will be said according to the preferred embodiment of institute's accompanying drawings It is bright.

Fig. 1,2 are referred to, is the three-dimensional exploded view and constitutional diagram of the first embodiment of human face recognition module of the present invention, such as schemes It is shown, human face recognition module of the present invention, comprising：One substrate 1；

The substrate 1 has one first plane 11, and first plane 11 is provided with one first lens group 111, one second lens group 112nd, an infrared LEDs group 113 and an image processor 114, and be electrically connected with respectively with the substrate 1, the infrared LEDs group 113 have one first infrared LEDs 1131 and one second infrared LEDs 1132 and are mutually adjacent to the foregoing left side of second lens group 112 Right both sides.

First lens group 111 filters with more one first eyeglass 1111 and one first lens base 1112 and one first The image sensor 1114 of piece 1113 and 1 first, and sequentially lamination is set the grade element.

Second lens group 112 filters with more one second eyeglass 1121 and one second lens base 1122 and one second The image sensor 1124 of piece 1123 and 1 second, and sequentially lamination is set the grade element.

Referring to Fig. 3, being the second embodiment stereogram of human face recognition module of the present invention, as illustrated, the present embodiment portion Separation structure is identical with aforementioned first embodiment, therefore will not be described in great detail herein, only the difference of the present embodiment and aforementioned first embodiment It is in and has more a housing group 2 in the present embodiment, the housing group 2 has one first housing 21 and one second housing 22 and one the 3rd The correspondence of housing 23 is spaced located at foregoing first plane 11, and is covered and protected foregoing image processor 114, and this first and second The correspondence of housing 21,22 covers an open-work 211,221 is offered at first and second infrared LEDs 1131,1132, make this first and second Infrared LEDs 1131,1132 parts provided with foregoing open-work 211,221 by exposing first and second housing 21,22.
