Abstract

The invention discloses an embedded face recognition terminal capable of overcoming modeling numbers. The terminal comprises a digital signal processor connected with a server. The digital signal processor is connected with a video acquisition module, an audio module, a synchronous dynamic storage and a general purpose input/output (GPIO) port. The digital signal processor further comprises a secure digital (SD) card and a flash memory, wherein the SD card serves as face model and ID number storage space, and the flash memory serves as storage space of ID numbers, recognition records and the like. The embedded face recognition terminal capable of overcoming modeling numbers can not only call out corresponding images from N face models for determination according to ID numbers, but also increase the embedded face recognition terminal modeling number greatly.

Description

A kind of embedded human face identification terminal that can overcome the modeling number

Technical field

The present invention relates to a kind of embedded human face identification terminal, concrete relate to a kind of embedded human face identification terminal that can overcome the modeling number.

Background technology

Nowadays embedded human face identification terminal; On market, just used by more and more; But its shortcoming is also significantly come out; Be exactly the modeling number that can store of terminal generally be 200-2000 people, at present embedded human face identification terminal modeling number surpass 2000 people be difficult to reach, this is mainly caused by three aspects:

The terminal all is stored in modeling face image, record etc. on the flash memory FLASH in design, and the modeling image belongs to three-dimensional, and two dimensional image needs more storage space relatively.

On the other hand, flash memory is on physical hardware, and its storage space does not also surpass 2000 people at present, has surpassed exactly, and its cost performance is also difficult at present in marketing.

Moreover the recognition mode of use 1:N is when the people discerns at the terminal; The image that removes to seek the face of homogeneity from N model can be spent for a long time in the terminal; Access and compare, thereby make judgement, this is on the speed of Flame Image Process; Can surpass one second in addition reach one assign to two minutes recognition time, the utilization in market is difficult to accepted.

Summary of the invention

For overcoming deficiency of the prior art; The present invention aims to provide a kind of embedded human face identification terminal that overcomes the modeling number; This invention not only can be according to ID number; Instantaneously access corresponding image from N faceform and judge with it, can also improve embedded human face identification terminal modeling number greatly.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:

A kind of embedded human face identification terminal that overcomes the modeling number; The digital signal processor that comprises a Connection Service device; Said digital signal processor is connected with video acquisition module, audio-frequency module, synchronous dynamic random access memory and GPIO I/O port, and said digital signal processor also has a SD storage card as faceform, ID storage space, a flash memory as storage spaces such as ID numbers, identification record.

Further, also be connected with one in the said SD storage card circuit as the IC-card mouthful RS-232 serial line interface of swiping the card.

Principle of work of the present invention is following: the present invention through improving electric wiring, sets up two functions: the function of swiping card of IC-card at the embedded human face identification terminal; The memory function of the SD card of external hanging type.Carry out the faceform when gathering when the people stands in the recognition of face terminal, adopt 1: 1 pattern, after faceform's collection, import IC-card again ID number, make ID number corresponding with this faceform.The content of core is through Development of Software, only is placed on ID number on the flash memory, is placed on for faceform+ID number on the SD card of external hanging type.Before the people stands in the terminal, swipe the card earlier, processor is according to ID number, instantaneously accesses corresponding image from N faceform and judges with it.

Compared with prior art, the present invention has following beneficial effect:

1. take few flash memory space ID number of the present invention;

2.ID number unlike image, its transmission speed is fast;

3. thereby the present invention increases modeling number, 2G through increasing SD card memory capacity

The SD card can make the modeler number be increased to 10,000, and the SD card of 8G can make the modeler number reach 100,000, by that analogy.

4. swipe the card+recognition of face, taken into account people's custom;

5. swipe the card+pattern of recognition of face, process is taken time and is no more than one second.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
