With Alipay, the wechat popularization that pays of barcode scanning that is representative and universal, barcode scanning is paid day by day come into vogue, barcode scanning pays from novelty to knowing, arrive acceptance, application again and promote so that large-scale business is super, general merchandise, market and other Commercial Complexes need to expend substantial amounts of human and material resources, financial resources to transform traditional POS. And if the simply simple payment function software directly using transformation, the operation for cashier has higher requirement, and the probability made mistakes is greatly promoted, and such software compatibility is poor, the friendliness reduction of user. Meanwhile, very easily there is cash register queuing phenomena in business super, the market etc. bigger artificial abortion, reduces the consumption experience of client. How to make traditional POS combine with novel cash register mode and system and have become as the thorny problem that a lot of business is super, general merchandise is encountered.
Common practice in the market is that POS producer directly upgrades cash register software, and another way is to use the software of only payment function. The POS producer that first method uses is while a large amount of human and material resources of consuming, financial resources carry out upgrading, it is necessary to businessman coordinates.This mode in very easily making former POS the information of accumulation, data, content be set etc. be damaged, it is also possible to bring system compatible sex chromosome mosaicism. First scheme is easier to realize in POS, but the operational requirements of cashier is improved, and when the personnel of checking are more, cashier very easily inputs the amount of money by mistake so that the friendly that software uses is poor.
Design, scheme and the Technology design that " a kind of barcode scanning based on OCR pays cash register software amount of money identification system " is contemplated to solve these problems and proposes. Native system can identify the settlement amounts of POS accurately by optical character recognition OCR technique, and the amount of money automatically filling payment software completes to pay.
Summary of the invention
Can support that again barcode scanning pays to realize neither carrying out original POS upgrading, the present invention provides a kind of system, and commodity total amount that when this system by installing barcode scanning payment software to realize checkout on the existing cashier's machine of trade company, barcode scanning payment software obtains on cash register software automatically also carries out barcode scanning payment. Arrange the settlement amounts region of the former cash register software of trade company when initial installation barcode scanning payment software, when recalling barcode scanning payment software by cash register keyboard during clearing, predeterminable area can be carried out sectional drawing and preserve by barcode scanning payment software automatically every time. Then barcode scanning payment software utilizes the OCR technique picture to preserving to use opencv computer vision storehouse to carry out pretreatment, finally convert images into binary image preserving clearly, it is identified training to the numeral of screenshot area again through OCR technique, reduce its identification error, and produce its distinctive language pack. Pay so that tradition POS realizes superposition barcode scanning in tradition POS by docking native system, and preserve the integrity of former POS, reduce to greatest extent tradition POS improvement cost and the lifting to operating characteristics.
Its summary of the invention be attributed to following some:
(1) in the former POS of trade company, settlement amounts region is intercepted and preserves;
(2) picture preserved after intercepting is entered pretreatment, and carry out pretreatment by calling opencv computer vision storehouse of increasing income, picture is carried out binary conversion treatment, micronization processes, picture burn into picture expansive working to improve the discrimination of picture;
(3) image after processing being preserved, in picture, the amount of money is black, and background is white;
(4) to identifying that the character being likely to occur on picture is identified training error correction, to reduce identification error, it is ensured that discrimination, final generation is for the language pack of this cash register software;
By the language pack produced, the POS of former trade company is coordinated to complete the combination of barcode scanning payment system and the legacy system of trade company.
Technical scheme
(1) select, according to the practical situation of cash register software, the region that settlement amounts occurs when barcode scanning payment software is installed, and preserve the rectangular coordinates in this selection region, preserve the upper left corner and the lower right corner or preserve the upper left corner and the width of rectangle, height, it it is all full screen display due to cash register software, the invariant position of the display amount of money, so by preserving the region that this coordinate avoids the need for selecting settlement amounts to occur every time, as long as arranging once.
(2) by cash register key activation barcode scanning payment system, and before payment system shows, complete to select the sectional drawing in region, and preserve into picture.
(3) the barcode scanning payment system picture to preserving uses opencv computer vision storehouse to carry out pretreatment, carries out binaryzation so that it is transfer black white image to.
(4) barcode scanning payment system uses OCR technique to be identified training for the character on picture, produces this distinctive language pack of cash register software, is then identified and extracts settlement amounts to pretreated picture and automatically fill the payment of payment system.
