Abstract
The invention uses computer electronic image processing technique and advanced software management system to perform automatic positioning and automatic recognition between original seal and target seal, it improvges the reliability of recognition and realizes automatic management of seal recognition for finance system.
Description
The present invention relates to Computer Applied Technology, especially about the processing of computing machine electronic image, recognition methods and the system of seal.
Mostly the seal recognition methods used of bank at present is manual operations, and the original seal that the seal on the check and client are stayed looks like to carry out manual knuckle to be compared, and this original comparison method human factor is many, poor accuracy, workload are big.The recognition methods of a kind of computing machine seal is also arranged, what adopt is the pattern-recognition mode, it is right that seal is carried out aspect ratio as extract minutiae, this recognition methods has following deficiency: 1) because firmly different when with an official seal affixed, the background difference of paper, the ink paste different in kind, feasible different with the feature of target image extracted twice to original image, the accuracy of unique point comparison is restricted; 2) the selection quantity of unique point is difficult to rationally, and selected element is few, is not enough to reach the contrast purpose, and selected element is many, makes the design system complexity, and data volume is big.
The objective of the invention is to overcome the deficiency of above-mentioned prior art, adopt how much comparison methods of seal picture, utilizing the computing machine electronic image to handle means will need the seal discerned and deposit in the Computer Database client's original seal in and carry out full images and contrast automatically.
Seal recognition methods among the present invention is the original seal picture of client and related data to be deposited in set up archives in the Computer Database, and the target seal picture on the bill that needs are differentiated looks like to carry out the geometric position by video camera input computing machine with original seal and compares.Two kinds of comparison modes are arranged: 1) knuckle comparison, at first the original seal in the database is looked like to amplify or dwindle processing, recover the seal real image and make it consistent, be presented on the small displays on the service window, then by manually carrying out the knuckle comparison with bill seal image size.2) accurately comparison, with the target seal picture on the bill by in the colour TV camera input computing machine and be presented on the main frame display monitor central monitoring system, original seal picture in the database also is transferred on the main frame display monitor central monitoring system, by computer control the target seal is looked like to be rotated then and translation makes it to overlap fully with original seal picture, again the stroke of each word on the seal is scanned whether differentiate two seals in full accord.
Seal recognition system among the present invention is to go up client's original seal picture is taken in main frame (5) being furnished with the camera-shooting table of illuminating lamp (3) by colour TV camera (4), deposits hard disk in and set up archives after image card carries out Flame Image Process; Locate to be equipped with 3 cun displays and a keypad (2) that links to each other with main frame (5) at service window (1), by keypad (2) main frame (5) being sent instruction is presented at original seal picture and interrelated data on the display monitor central monitoring system (7),, a level or move automatically on display monitor central monitoring system perpendicular to the parting line (10) of two seal pictures, printer (6) can be with the operational data printout.Pictorial data card, image compression card, image display card, window signal control card and Chinese Card are housed in main frame (5).The management software that is used with this system also is housed: three grades of rights management software, build library software, check other management software of software, form software, backup software and banking in main frame.Three totalitarity limit management software comprises bank management personnel software, administration software and sales counter operating personnel software.Be provided with the various parameters of bank's work such as account number, subject, sales counter window, definition office staff password in the bank management personnel software; Be provided with reporting system in office staff's management software, standby system and window sales counter operating personnel's password; In the sales counter operating personnel software customer data base is arranged, data for updating, (delete, report the loss, freeze etc.) the identifying stamp system.
The present invention has following advantage:
1. by computing machine seal is compared automatically, human eye judges at last, and is directly perceived, accurately, easy to operate, high efficiency.
2. can get rid of paper background, ink paste character, the not influence of equal extraneous factor of affixing one's seal firmly.
3. realize the automatic management of bank and other financial mechanism.
Description of drawings:
Fig. 1 is a system chart of the present invention, wherein: 1-service window, 2-keypad, 3-camera-shooting table, 4-colour TV camera, 5-main frame, 6-printer, 7-display monitor central monitoring system
Fig. 2 is the seal identification synoptic diagram of display monitor central monitoring system of the present invention, and (a) figure is seal show state figure, wherein: the original seal picture of 8-, 9-target seal picture; (b) figure is seal status recognition figure, wherein: the 10-parting line
Below in conjunction with accompanying drawing narration embodiments of the invention.
1. build the storehouse: the original seal of client is placed on the worktable (3) → definition family number, subject etc. → by video camera (4) the seal picture is taken in main frame (5) → input client interrelated data (title, mailing address, bank of deposit etc.) → image card image is handled, with compression of images → deposit in hard disk.
2. slightly than (knuckle comparison): as client's check during to service window (1), this window sends instruction by keypad (2) to main frame original seal picture and data is presented on the display of 3 cun (1: 1) in the service window (1), again seal is looked like to handle the recovery virgin state.The staff carries out knuckle comparison (two image sizes are just the same) with target seal on the check and the original seal on the display.Then pass through as no problem, accurately compare if any problem.
3. smart ratio: check is put into worktable, (3) on → video camera, (4) the target seal picture → microcomputer of picked-up in the check accesses original seal picture → target seal picture and original seal are looked like to be presented at display monitor central monitoring system, (7) on → the target seal is rotated system controlled by computer and translation → original seal picture and target seal image position on fully heavily be incorporated in display monitor central monitoring system, (7) go up to show → one level or perpendicular to two kinds of seals as the interface line, (10) on display monitor central monitoring system, move → differentiate the coincidence degree of two seal words at the interface automatically.(the parting line top is original seal picture, and the below is a target seal picture).
