Abstract
The utility model discloses a kind of IC-card sheet texture recognition module, comprise image acquisition module and IC texture recognition computing module; Described image acquisition module comprises a paving and helps light source and electronic collection device, and described IC texture recognition computing module comprises digital signal processor, and described digital signal processor connects CMOS camera lens module.The utility model can identify IC chip texture above IC-card sheet, and dependable performance is stablized, and whether effectively can detect the card with IC chip and user when using IC-card with correct direction plug-in card; Be applicable to the card-reading apparatus draw-in grooves such as ATM control to identify application.
Description
Technical field
The utility model relates to a kind of recognition system, in particular, relates to a kind of IC-card sheet texture recognition system.
Background technology
At present, user often because general idea inserts draw-in groove with the plug-in card direction plug-in card of mistake or the card do not supported by the card-reading apparatus such as ATM when using the card-reading apparatus such as ATM cash dispenser, is spued after ATM identification, is wasted the time, reduced efficiency of service;
There is relevant product can identify the plug-in card direction of magnetic stripe card on the market for magnetic stripe card.
And have for the identification of IC-card sheet the mode identification using contact on the market, but actual use procedure can run into the situation that the impact such as contact damage, IC surface oxidation, dust causes contact and the loose contact of IC chip, and serviceable life is short, and False Rate is high.
Utility model content
The purpose of this utility model is to provide a kind of IC-card sheet texture recognition module, addresses the deficiencies of the prior art.
The technical solution adopted in the utility model is: a kind of IC-card sheet texture recognition module, comprises image acquisition module and IC texture recognition computing module; Described image acquisition module comprises a paving and helps light source and electronic collection device, and described IC texture recognition computing module comprises digital signal processor, and described digital signal processor connects CMOS camera lens module.
Digital signal processor (DSP), is connected with CMOS camera lens module, and the IC texture image data collected is transported in digital processing unit and processes by CMOS camera lens module, and then generates IC textural characteristics storehouse and carry out the comparison of textural characteristics value.
IC texture recognition computing module is connected with PC by USB interface, UART interface, bluetooth module, WIFI module, carries out image display and texture searching upgrading renewal.
The beneficial effects of the utility model are: help light source to drastically increase picture quality and picking rate by external paving.Security is high, and IC-card sheet texture recognition module has gate control function, and card texture must be recorded in inside texture searching, otherwise does not pass through card inserting mouth.Can prevent client from using nonstandard card, and prevent user with the plug-in card mode plug-in card of mistake.
Unified management: the IC-card that equipment user can define oneself accreditation uses equipment, only need allow the IC-card texture typing IC-card sheet texture recognition module used to set up texture searching oneself.

Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the embodiment of the present invention is further described.At this, illustrative examples of the present utility model and illustrate and be used for the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, IC-card sheet texture recognition module, comprises image acquisition module and IC texture recognition computing module.IC texture recognition computing module is connected with the collection of image acquisition module, and the view data collected is flowed to IC texture recognition computing module by image acquisition module, as Fig. 1.
The image acquisition module of the present embodiment comprises electronic collection device and paving helps light source, described electronic collection device comprises optical lens (LENS) 1, support (HOLD) 2, optical filter (IR) 3, cmos sensor (SENSOR) 4 and FPC soft board 5, as shown in Figure 2.
IC texture recognition computing module by view data extract minutiae after extreme value filtering, once level and smooth, sharpening, secondary filtering, binaryzation, the process of refinement software, and stored in IC texture searching, as shown in Figure 3.The unique point that above-mentioned IC texture recognition computing module extracts is embodied in as shown in Figure 4: the destination node of IC texture, bifurcation, isolated point, short grain.
Image acquisition module is placed in the upper right side of draw-in groove by the present embodiment, and the IC chip of IC-card is all placed in the upper right side of card face, so the camera lens of image acquisition module is just in time placed in directly over IC chip during user's plug-in card; Gather the view data that module is only responsible for gathering this region of IC chip, ensure that validity and the accuracy of collection.
The present embodiment embody rule process is expressed as follows: when user is with correct plug-in card mode (as Fig. 5) plug-in card, image acquisition module gathers card picture, and image data is transferred to IC texture recognition computing module, eigenwert is extracted through above-mentioned software processes, compare with IC texture searching, if eigenwert is present in texture searching, then module generation control signal control draw-in groove is let pass to card, otherwise closes draw-in groove.
Meet following three simultaneously:
A. card has IC chip;
The textural characteristics of b.IC chip Already in our IC texture searching;
C. user is with correct plug-in card mode plug-in card (as Fig. 5);
IC texture recognition computing module provides a level signal and controls draw-in groove switch opens draw-in groove, and other situations all close draw-in groove; Thus achieve the card-reading apparatus draw-in groove control identification application such as ATM.In a word, aforementioned is preferred implementation of the present utility model, and under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
