Description

Recognition of face intelligent control circuit

Technical field

The utility model relates to a kind of control circuit, and specifically a kind of recognition of face intelligent control circuit, belongs to recognition device technical field.

Background technology

Recognition of face, as the high-tech discriminating means of one, is usually used in various public arena, for safety provides safeguard; Product core technology is Static Human Face identification, be characterized under individual access personnel coordinate, recognition of face to be realized in feature region, so the application of Static Human Face identification is only confined to the subsidiary function of gate control system, i.e. a kind of closely face recognition technology under controlled conditions.This system requirements user must be that faced by front, video camera could obtain high-quality facial image simultaneously, and once can only identify a people, and environment also has the requirement of better quality to external world, such as light.The demand that much cannot meet present market due to the limiting factor be subject to when therefore Technology of Static Human Face Recognition uses therefore needs provides a kind of control circuit that can carry out recognition of face in the dynamic case, facilitates people's stream calculation etc.

Utility model content

The utility model proposes a kind of convenient control circuit the technical solution of the utility model calculating the stream of people of dynamic human face identification of carrying out to be achieved in that

A kind of recognition of face intelligent control circuit, comprise processor, back-stage management server, multiple goal Face tracking and recognition module, imageing sensor, dynamic noise reduction module, synchronous dynamic random access memory and screen scrambler, wherein back-stage management server, multiple goal Face tracking and recognition module, imageing sensor, dynamic noise reduction module, synchronous dynamic random access memory and screen scrambler are electrically connected respectively at described processor.

Preferably, described multiple goal Face tracking and recognition module comprises face amplification module and tracking and identification module.

Preferably, described multiple goal Face tracking and recognition module is video camera.

Preferably, described dynamic noise reduction module is RC filtering circuit.

The recognition of face intelligent control circuit that the utility model provides is undertaken by multiple goal Face tracking and recognition module, carry out the tracking of target dynamic, and data are stored, obtains information clearly by dynamic noise reduction module, thus the statistics of the stream of people can be carried out.The utility model can realize dynamic human face identification, clear, and usable range is wide.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is schematic block circuit diagram of the present utility model.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, a kind of recognition of face intelligent control circuit of the utility model, comprise processor 4, back-stage management server 1, multiple goal Face tracking and recognition module 2, imageing sensor 3, dynamic noise reduction module 5, synchronous dynamic random access memory 6 and screen scrambler 7, wherein back-stage management server 1, multiple goal Face tracking and recognition module 2, imageing sensor 3, dynamic noise reduction module 5, synchronous dynamic random access memory 6 and screen scrambler 7 are electrically connected respectively at described processor 4.

It should be noted that described multiple goal Face tracking and recognition module 2 comprises face amplification module and tracking and identification module, may be used for multiobject tracking, and the amplification of face can be carried out, further can optimized image.

It should be noted that described multiple goal Face tracking and recognition module 2 is video camera.The intelligent camera of preferred use high definition, can support the CCD/CMOS imageing sensor 3 of 1,000,000/ten million pixel.

Imageing sensor 3 can use the product of different brands such as: CCD Sony, Sharp CCD image sensor, CMOS: Sony, Panasonic, AptinaCMOS image sensor etc.

It should be noted that described dynamic noise reduction module 5 is RC filtering circuit, the interference of impurity can be effectively reduced.Preferably, back-stage management server 1 is webserver supplier, and has the pattern of CMYK (printing color pattern is respectively cyan, magenta, yellow and black) and RGB (red, green, blue three look).

It should be noted that optical signalling is converted to analog current signal by the direct of imageing sensor 3, current signal, through amplifying and analog to digital conversion, realizes the acquisition of image, storage, transmission, process and reproduction.Screen scrambler 7, for providing video compress or separating compression functions, completes the collection of pictorial data or recovery etc.; Processor 4 is mainly for the treatment of all dynamic datas, and process and the reduction of carrying out image reappear, and preferably, it can adopt the computing machine of double-core, and with cache memory, in order to synchronous recognition of face.

It should be noted that, the utility model recognition of face intelligent control circuit, the communication modes of its network video server adopted is also by originally simple cable network, become and adopt wired and wireless WIFI (802.11abg communications protocol) compatibility, wireless transmission range, also by original tens meters (30-100 rice), develops into current tens kilometers (30-50 kilometers).

The places such as the utility model is arranged in corridor, supermarket, station, community, office, prison, Internet bar, school are as passenger flow statistical system, the information traced into is passed to back-stage management server 1 by processor 4 by multiple goal Face tracking and recognition module 2, synchronous dynamic random access memory 6 is for store images, preferably, DDR internal memory is selected.
