Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Fig. 1 for one embodiment of IMAQ and data processing method in the present invention method flow diagram, it is including following
Step：
Step S10：Obtain banknote image analog signal line by line using line scan image sensor.
When PLD or application specific integrated circuit control exposure, light source luminescent and the output of line scan image sensor
The coherent signals such as clock.When obtaining banknote image line by line, the illumination mode of light source can change line by line, such as can be saturating using white light
Penetrate, white light reflection, infrared transmission, infrared external reflection, ultraviolet reflectance, the illumination mode such as various reflection of monochromatic lights or transmission, it is each luminous
The fluorescent lifetime of mode can also be preset.Line scan image sensor can be gathered exposes different banknote images line by line.
Step S20：Analog to digital conversion is carried out to acquired banknote image analog signal and obtains data image signal.
Step S30：Data image signal is corrected.
Digital correcting image signals are referred to carry out gray correction to the banknote image pixel collected.Due to uneven illumination
The reason, the paper collected such as the luminous sensitivity of each sensitivity speck of even, line scan image sensor, dark current be inconsistent and non-linear
Coin image has serious gray scale inconsistency, it is necessary to carry out gray correction, could obtain correct banknote image.Above-mentioned ash
Degree correction refers to linearly or nonlinearly convert the banknote image gathered.Specifically to the mould of line scan image sensor
Intend output valve, that is, the banknote image being acquired is corrected after analog to digital conversion, make it correctly to reflect that banknote image is believed
Breath.Specific practice is the banknote image the being acquired sampling exported to line scan image sensor, quantify after, to its bright output and
Dark output carries out linearly or nonlinearly conversion compensation.Simple to realize, the present embodiment uses linearity correction.
Meanwhile, if line scan image sensor output valve is made up of several sections of line scan image sensors, each section of linear array figure
As sensor can be exported simultaneously, it is accomplished by resequencing to every row signal after being digitized into, that is, resets, can be write by control
The address for entering or reading RAM is realized, obtains the banknote image information exported by banknote image pixel order.Processing is reset typically to exist
Complete, can also be synchronously completed with correction process before correction process.
Step S40：Data image signal after corrected processing is handled.Described enters to data image signal
Row processing, will the row image pixel by pixel and the normal data that prestores be compared, detect bank note covering relevant information in the row,
Including：（1）Carry out coin signal；（2）Bank note overlay area beginning and end position；（3）Bank note slit and transparent region position.Its
In, the normal data prestored refers to before imaging sensor collection banknote image, i.e., when being covered without bank note, gather and protect in advance
The data line for the identical illumination mode deposited, such as white light transmittant, infrared transmission, white light reflection, infrared external reflection image data, can be with
It is the background of system acquisition banknote image to think this data line.
By the way that current line image pixel by pixel and the normal data that prestores are compared, if a number of pixel is super
Cross given threshold, then it is assumed that have and carry out coin signal, into bank note overlay area；The position for initially entering bank note overlay area is bank note
Overlay area starting position, the position for finally leaving bank note overlay area is bank note overlay area end position；If being covered in bank note
Non- bank note overlay area is detected between cover area beginning and end position, then the slit as bank note and transparent region position
Put.
Therefore, by that often will be compared with normal data row image pixel by pixel, can just be detected according to difference coin signal,
The position of bank note overlay area beginning and end and bank note slit and transparent region positional information.Detect and opened after carrying out coin signal
Begin collection effective image.Bank note overlay area positional information, includes position and the bank note of bank note overlay area beginning and end
Slit and transparent region positional information, it is direct or encoded after as being exported in additional data embedded images row at data signal
Device is managed, digital signal processor receives data using video input interface.These data can not also be used in embedded images row
Other interfaces are transferred to digital signal processor.For bank note slit（Or transparent region）The coding of positional information, can be used
Potting gum mode is encoded, i.e., each pixel is represented without and with slit respectively with 0 and 1（Or transparent region）, 8 potting gums
With a byte code；Run- Length Coding compressed data can also be used.
Traditional two pairs of infrared tubes of use（Receive and launch to pipe）Detection carrys out coin signal method, when bank note has inclination
Error is very big, substantially increases accuracy of detection come coin signal using the inventive method detection, also eliminates infrared tube.Tradition is logical
Analysis piece image data are crossed, border therein and slit position is detected, because by shadow interference, precision is limited, have impact on
Identification and false distinguishing processing, the signal gathered when the inventive method without bank note using with covering are compared to detection border and slit
Position, substantially increases accuracy of detection.
It is above-mentioned that data image signal is handled, can also be right in addition to detecting and coming coin signal and bank note overlay area
Often row image pixel carries out statistical disposition, for example, the difference of the pixel sum of the row data, pixel average, front and rear pixel is absolute
Value and, the difference quadratic sum of the difference quadratic sum of front and rear pixel and forward data etc..The digit specified can be used（Such as 2 bytes）Protect
Deposit a data.Special, because data bit width is limited, above statistics can give up low data, retain the height specified
Position data.
Above-mentioned additional data, which may also include, comes coin signal, the position of bank note overlay area beginning and end, bank note slit
With transparent region, the often statistical information and line number of row pixel, frame number, Exposure mode etc..Obtain after additional data, be embedded into
In image line.Specifically, the width of increase image line, to accommodate the additional data, is placed on head or the afterbody of image line.
The other positions of image line can certainly be placed on, but processing complexity can be increased.
In the above method, result is encoded, i.e., result data encoded, such as to slit data encoding,
Various entropy coding methods, such as Run- Length Coding can be used, or simply using two-value data encapsulation, i.e., with a byte code 8
The pixel of binaryzation.
Step S50：Output image data carry out banknote image detection and identification to digital signal processor.
Data image signal after correction is output to digital signal processor together with additional data and carries out banknote image
Detection and identification.
Transmitted after being handled in assisting process circuit banknote image and being embedded in additional data, then by banknote image signal
To digital signal processor, digital signal processor is conducive to rapidly to obtain boundary information, bank note breakage, Exposure mode
Deng image parameter information, the workload of digital signal processor is reduced, paper money recognition speed is substantially increased.

The 0th ~ 1439 byte location is placed on, wherein 48 ~ 1251 be the view data of bank note overlay area, other is without the bank note area of coverage
The view data in domain；1440 ~ 1535 positions are additional data, totally 96 additional data positions.The left margin of bank note is 48, the right
Boundary is 1251.Specifically, additional data includes line number, frame number, Exposure mode, the beginning and end position of bank note overlay area successively
Put, slit（And transparent region）The statistical information such as position data and pixel average.Usually, as long as infrared or white light perspective row
Detect slit position（Transparent region）, row is as detected, other rows need not be detected, as non-detection row, then these non-detections
Capable corresponding slit position data region can be used for the last slit position data detected of storage, so as to reduce in detection row
Deposit the byte number of slit position data.

Before processing execution is corrected to data image signal.Coin signal and bank note overlay area will be come to data image signal detection
The step of processing obtains additional data is placed on before aligning step.Data image signal is carried out the processing can before correction or
After correction.It is 8 bit image data after correction, then by current line image pixel by pixel for example, being 10 raw image datas before correction
10 initial data before correction process can be used by being compared with the normal data that prestores, can also use 8 after correction process
Bit image data are handled.But to row in image pixel value carry out statistical disposition, such as gone in pixel sum, should also be right
Data image signal is corrected after processing and performed.
If line scan image sensor output valve is made up of several sections of line scan image sensors, each section of linear array images sensing
