Mancarried device for the invoice scanning recognition of the present utility model compared with prior art, have following beneficial effect: (1) selects the zone of image recognition by frame, improve specific aim and the efficiency of inputting of typing invoice information, shortened the time of invoice information typing; (2) can the character result of scanning recognition be edited and revise, be convenient to user's operation.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the mancarried device of invoice scanning recognition.
Embodiment
The structured flowchart of the utility model provides a kind of mancarried device for the invoice scanning recognition, as shown in Figure 1, comprise housing, be provided with display module 2 and image unit 3 on the housing, be provided with microprocessor 1, storer 4, communication unit 5 and optical character identification unit 6 in the housing, display module 2, image unit 3, storer 4 are connected with communication unit and are connected with microprocessor 1 respectively, and display module 2 comprises liquid crystal touch screen.
The workflow that should be used for the mancarried device of invoice scanning recognition is: at first image unit 3 is by taking pictures to invoice, it is transferred to microprocessor 1, microprocessor 1 stores the invoice picture file in the storer 4 into, and pictorial information is presented on the liquid crystal touch screen 2, then the invoice project view data that will identify by the choosing of touching display screen frame is sent to optical character identification unit 6 and identifies, the character result of identification is presented on the liquid crystal touch screen, and recognition result is kept in the storer 4 with the tax authority's discernible form of management background system.Also be provided with for load module on the display module 2, load module can be used for the editing character recognition result, also can be used for triggering the transmission character data and manages background system to the tax authority.The user compares the actual information of invoice with the character identification result that is presented on the liquid crystal touch screen, character result such as identification conforms to invoice information, then can the control inputs module character result who identifies be sent to tax authority's management background system, microprocessor 1 is about to the character identification result file transfer to communication unit 5, and communication unit 5 sends to the character identification result file by modes such as wireless (such as GPRS, CDMA, 3G, WIFI, bluetooths, infrared) the management background system server of the tax authority again according to certain communication protocol; If any not being inconsistent, the user can the control inputs module edit and revise the recognition result of character on liquid crystal touch screen, then use wireless communication mode to send to the management background system of the tax authority by authentication and by certain network communication protocol, the management background system of the tax authority is by the tax control code of the invoice character recognition file generated invoice that receives, compare with the tax control code on the invoice, tax-controlled invoice is carried out the discriminating of the true and false, the information exchange of identification result is crossed the communication unit 5 that is wirelessly transmitted to mancarried device, and is presented on the liquid crystal touch screen.
The accuracy of invoice picture recognition is mainly relevant with the picture quality that image unit 3 gathers.The utility model is to improve in the following manner invoice to gather picture quality: (a) image unit 3 built-in automatic focus chips are used for preventing the invoice image acquisition process being difficult to identification because the factor such as rock causes captured picture smudgy; (b) display pixel of liquid crystal touch screen is more than 2,000,000 or 2,000,000, guarantees the display effect of literal on the picture; (c) microprocessor 1 is controlled liquid crystal touch screen when the beginning image acquisition.The mancarried device that the utility model is used for the invoice scanning recognition can be smart mobile phone or panel computer, included microprocessor 1, display module 2, image unit 3, storer 4 and the communication unit 5 of mancarried device all can be integrated on smart mobile phone or the panel computer, 6 of optical character identification unit can be used as the part of smart mobile phone or panel computer software systems to be incorporated in the true from false of bills discriminating software systems, and true from false of bills discriminating software can be communicated by letter with the management background system by above-mentioned communication.
Tradition invoice scanning device does not have the function of selecting picture material to be identified at the display screen upper ledge, therefore the content that will identify is the picture integral body that image collecting device gathers, wherein may comprise a part of redundant information, may comprise that also a part is difficult to identify or be identified as the information of mess code, the utility model adopts the touch screen linking frame to select function effectively to solve this problem, has improved the efficiency of inputting of invoice project information.Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these utility models.Concerning the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of submitting to.
