Problems solved by technology

[0004] However, when the position of the printed barcode is greatly inclined due to the problem of paper feeding when the report page is printed, or the barcode is greatly inclined due to manual hand sticking, the existing barcode reading method is used. It is difficult to accurately identify the content of the barcode without a reading device, especially when the tilt angle is very large, the existing barcode reading device cannot even recognize it at all
[0005] Once such a situation occurs, the identified maintenance content information will be wrong, causing the wrong maintenance content to be stored in the database, resulting in management confusion, making the staff have to work hard to find out which barcode on the maintenance order is skewed , which is time-consuming and labor-intensive, thus causing inconvenience to the staff's document management work

Embodiment 1

[0058] figure 1 It is a structural block diagram of the document image management system according to Embodiment 1 of the present invention.

[0059] Such as figure 1 As shown, in the first embodiment, the document image management system 100 is used to manage the barcode images in the document pages not shown in the figure. A document image management system 100 includes a multifunction printer 10 and a document image management device 20 .

[0060] The multifunction printer 10 has a scanner unit 11 and a scanner-side communication unit 12 .

[0061] Scanning part 11 scans the document page that is printed with document content and contains at least one barcode into such as image 3 Start page image shown. In the first embodiment, the document page is a maintenance report, and two barcodes are attached to the maintenance report.

[0062] The scanning side communication unit 12 is connected to the scanning unit 11 , and sends the scanned initial page image to the document...

Embodiment 2

[0162] The following is the description of the second embodiment.

[0163] In the second embodiment, the same symbols are assigned to the same structures as those in the first embodiment, and the same descriptions are omitted.

[0164] Figure 16 It is a block diagram of the barcode recognition device according to the second embodiment of the present invention.

[0165] Such as Figure 16 As shown, the barcode recognition device 223 includes a conversion unit 23-1, a pixel setting unit 223-2, a search path setting unit 223-4, a pixel judging unit 23-5, a search acquisition unit 223-6, and a boundary line acquisition unit 223 -7. Inclination angle calculation unit 223-9, exclusion determination unit 223-19, inclination determination unit 223-10, inclination angle storage unit 223-20, completion determination unit 223-21, rotation straightening unit 23-11, correction control part 23-12, pixel correction part 23-13, recognition control part 23-14, barcode content storage part ...

Abstract

The invention provides a bar code identification apparatus, a document image management system and a bar code identification method. The bar code identification apparatus comprises a conversion portion, a pixel setting portion, a searching path setting portion, a searching acquisition portion, a boundary line acquisition portion, a determination portion, an inclination determination portion, a rotation straightening portion and an identification control portion, wherein the conversion portion carries out binary conversion on an image; the pixel setting portion sets an initial pixel; the searching path setting portion takes the initial pixel as a starting point pixel and sets a searching path; the searching acquisition portion searches and acquires an initial boundary point and a plurality of subsequent boundary points according to a determination result of a pixel determination portion; the boundary line acquisition portion acquires two boundary straight lines; the determination portion determines a black line according to a result of proportional included angle calculating; the inclination determination portion determines whether an inclination angle calculated by an inclination angle calculating portion is above a predetermined value; if the inclination angle calculated by the inclination angle calculating portion is above the predetermined value, a bar code is determined to be inclined; the rotation straightening portion carries out rotation straightening on the image; the identification control portion identifies a bar code image corrected by a pixel correction portion so as to acquire a bar code content.

Description

technical field [0001] The invention relates to a barcode recognition device, a document image management system and a barcode recognition method. Background technique [0002] With the rapid development of computer and information technology, bar codes have been more and more widely used in various industries. For example: in the maintenance service industry, in order to manage the maintenance service, the maintenance service provider needs the maintenance personnel to make a corresponding report according to the actual and specific maintenance service of the multi-function printer being repaired after completing the maintenance service page, and print or affix multiple barcodes on the report page, which contain maintenance information related to all maintenance services for the multifunction printer being repaired during this dispatch. [0003] The prepared report pages will be sent back to the maintenance service provider, and the input staff of the maintenance service p...
