Description
Technical field
Present invention relates particularly to a kind of bill images managing device, the bill image tube comprising the bill images managing device
Reason system and bill images management method.
Background technology
Under the trend of e-finance, Information Technology Methods have turned into the new business growth point of financial industry, quick, accurate
Really, efficiently realize that the information-based of routine work has turned into the financial unit such as bank increasingly urgent business needs.It is living in economy
Substantial amounts of paper list archive is produced in dynamic, in order to realize these enormous amounts, miscellaneous archives of paper quality electronics
Change storage, it is necessary to carry out the work such as document scanning, data inputting, artificial check and correction.Traditional manual entry mode, user needs to throw
Enter substantial amounts of human cost and time cost, not only raise operation cost, and input speed is difficult to be lifted, and error rate is difficult to
Reduction, many negative effects are brought to improving business processing timeliness, enterprise service quality.
In addition, be required for filing by hand for each bill, artificial enquiry, labor intensity is big, easily error, efficiency kimonos
Quality of being engaged in is low；And bill lacks backup, in case of floods, fire or worm mouse bite the loss for causing to be difficult to retrieve；Furthermore, bill
The network electronic transmission that can not be modernized, can not meet increasingly allegro Financial Demands.Therefore the management of electronic bill
Arise at the historic moment.
But when carrying out bill typing at present, mainly shot or two modes of scanner scanning by camera.But both
Mode still has the following disadvantages：
1st, efficiency is low, because being unable to batch processing, it is necessary to shoots or scans one by one；
2nd, the bill images obtained and former bill are not equidimension (always fixing A4 or A5 sizes), the bill of acquisition
The valid pixel of picture is low；
3rd, because bill is more frivolous, it is easy to place not just, it is probably askew to cause the bill images obtained, follow-up
Text identification in add by mistake know and rejection probability.
The content of the invention
The present invention is carried out to solve the above problems, it is therefore intended that provide a kind of bill images managing device, bag
Bill images management system and bill images management method containing the bill images managing device.
The present invention to achieve these goals, employs following structure：
<Structure 1>
The invention provides a kind of bill images managing device, have the feature that, including：First scanning acquisition unit,
Multiple bills placed simultaneously according to the first predetermined scan parameter pair carry out scanning for the first time to obtain comprising multiple bills
Each bill images as basic bill images the first scan image；Second scanning acquisition unit, according to the second predetermined scanning ginseng
It is several that multiple bills are carried out with second of scanning to obtain each bill images comprising multiple bills as conventional ticket image
The second scan image；Each Zhang Jiben bill images in first scan image are distinguished by primary image discrimination section；Substantially
Picture position determining section, corresponding picture position is obtained according to the basic bill images identified；Normal image interception portion, according to
Picture position intercepts corresponding conventional ticket image from the second scan image；And normal image storage part, for storing
Conventional ticket image, wherein, the first scanning predefined parameter at least includes the first scanning concentration value, and the second scanning predefined parameter is at least
Including the second scanning concentration value, the first scanning concentration value is more than the second scanning concentration value.
<Structure 2>
Further, present invention also offers a kind of bill images management system, have the feature that, including：Bill
As managing device, pair multiple bills placed simultaneously are scanned and intercept the conventional ticket figure corresponding with multiple bills difference
As being stored；And picture material identifying device, communicated to connect with bill images managing device, to the conventional ticket figure of interception
Character content as in is identified and stored for use in management, wherein, bill images managing device is<Structure 1>Bill
Image management apparatus.
<Structure 3>
Further, present invention also offers a kind of bill images management method, have the feature that, including：Using
Multiple bills that one scan acquisition unit is placed simultaneously according to the first predetermined scan parameter pair carry out scanning for the first time to obtain bag
Each bill images containing multiple bills as basic bill images the first scan image；Using second scanning acquisition unit according to
Second predetermined scan parameter carries out second of scanning to multiple bills and made so as to obtain each bill images comprising multiple bills
For the second scan image of conventional ticket image；Using primary image discrimination section to each Zhang Jiben bills in the first scan image
Image is distinguished；Corresponding image position is obtained according to the basic bill images identified using primary image position determining portions
Put；Intercept corresponding conventional ticket image from the second scan image according to picture position using normal image interception portion；With
And using normal image storage part storage conventional ticket image, wherein, it is dense that the first scanning predefined parameter at least includes the first scanning
Angle value, the second scanning predefined parameter at least includes the second scanning concentration value, and the first scanning concentration value is more than the second scanning concentration value.
The effect of invention and effect
According to bill images managing device involved in the present invention, bill images management system and method, because substantially
Image identifying portion is distinguished each Zhang Jiben bill images in the first scan image；Primary image position determining portions is according to distinguishing
The basic bill images not gone out obtain corresponding picture position；Normal image interception portion is according to picture position from the second scan image
The corresponding conventional ticket image of middle interception；And normal image storage part, for storing conventional ticket image, so, first,
Can pair simultaneously place multiple bills be scanned processing, i.e., to bill carried out batch processing, saved the time；Secondly,
Using simple, bill can arbitrarily be positioned over any position of scanning board；Again, the bill images of acquisition and former bill are equidimensions
, the valid pixel of the bill images of acquisition is high, has saved the internal memory of bill images occupancy；Finally, the bill images of acquisition are
The image of correct direction, has saved the flow in follow-up text identification, reduces the probability known by mistake with rejection.
