Abstract
The present invention relates to a postcode identification processing method and its equipment thereof. Said method incluees: taking out image containing postcodes from left-upper corner of a letter; separating out binary image of six postcodes and grey scale image of position coordinates of six postcode red blocks and postcode zone; making identification according to the binary image of six postcodes and delivering identification result; for unknown postcodes, using position coordinates of red blocks to find grey scale image and displaying it on screen; and according to the inputted code after manual identification, supplementing postcodes of the sorted letter. Said method can greatly raise letter-sorting efficiency.
Description
The present invention relates to the processing method of a kind of letter sorting machine postcode identification in course of letter sorting and be used for the device of this method.
Normally used optical character identification letter sorting machine is the postcode that appliance computer is read the letter upper left corner, according to read postcode letter is delivered to corresponding bin.Because different people are when post code writing, may on various envelope background colors, use various lettering pens to write into different fonts, thereby the modification of postcode is many especially, and the real-time of reading makes the reading of postcode than general text difficulty, cause the code identification rate lower than general text identification rate, and current computer discrimination itself does not just reach 100%, and letter sorting machine requires six postcodes all to know in letter is handled to sort letter, so, often refuse to know the branch of refusing that causes envelope letter owing to a postcode.It is 50% more that such about 90% individual character discrimination, actual letter sorting rate can only reach.
The objective of the invention is to have known the coding that in order to make full use of machine recognition in the course of letter sorting, and the coding of failing to discern is handled processing method that a kind of postcode that provides with the sorting rate that improves letter is discerned and the device that uses this method thereof.
In order to realize the foregoing invention purpose, the present invention has adopted following processing method to finish, and step is as follows:
Obtain the image that includes postcode from the upper left corner of letter;
From the described image that comprises postcode, isolate the position coordinates of the binary image of 6 postcodes, 6 postcode frame boxes and the gray scale image of zip code area;
Binary image according to 6 postcodes is discerned, and the output recognition result;
According to recognition result, the position coordinates of the unidentified postcode that goes out by red frame found gray scale image and be presented on the screen;
The postcode of the letter that is sorted according to the coding completion of importing after the manual identification;
Sort according to the postcode that identifies by sorter.
Use the device of above-mentioned postcode identification processing method, comprising:
Photoelectric scanner, the upper left corner of scanning letter is to obtain including the image of postcode;
Image storage unit links to each other with photoelectric scanner, is used to store the image that described photoelectric scanner scanning obtains;
Coding processing unit obtains the described image that includes postcode from described image storage unit, and isolates the position coordinates of the binary image of 6 postcodes, 6 postcode frame boxes and the gray scale image of zip code area according to this image;
The code storage unit links to each other with described coding processing unit, is used to store the red frame position coordinates and the gray scale image of described 6 postcodes of described coding processing unit output;
The code identification unit links to each other with described coding processing unit, according to the binary image of described 6 postcodes postcode is discerned;
Administrative unit links to each other with described code identification unit, obtains recognition result from described code identification unit, if there is the unidentified coding that goes out described code identification unit, then produces the position signalling of this unidentified coding that goes out;
The complement code processing unit, the position signalling of the described unidentified coding that goes out that receives that described administrative unit produces obtains the gray scale image of this relevant position from described code storage unit; With
The complement code unit links to each other with described complement code processing unit, and it comprises gray scale image display unit that shows and the input unit that is used to import the represented coding of this gray scale image to described complement code processing unit output;
Described complement code device also links to each other with described administrative unit by communication interface, and so that the complemented value of input is outputed to described administrative unit, described administrative unit is with the described postcode of this complemented value completion.
Owing to adopt technique scheme, if a cover letter sorting machine is joined two coding persons, actual letter sorting rate improves more than 30%, per capita treating capacity five, 6,000 envelopes letter per hour.Improve the utilization rate of letter sorting machine greatly, saved manpower, financial resources, material resources.
Fig. 1 is the postcode recognition process unit.
In block diagram shown in Figure 1, when letter deposits the image of the zip code area in the letter upper left corner in image storage unit 2 through the photoelectric scanner 1 of letter sorting machine, described image storage unit connects coding processing unit 3, coding processing unit 3 according to the image of storage isolate binary image, the 32 grades of gray scale images in zone, the letter upper left corner of 6 postcodes, the position coordinates of 6 postcode frame boxes is sent into code storage unit 4.Coding processing unit 3 can adopt the input computer, it is transferred to code identification unit 5 with the binary image of 6 postcodes, described code identification unit 5 can adopt the identification computer, described code storage unit 4 can adopt the output computer, and this calculates the information content of function storage five, 60 envelopes letter.Code identification unit 5 is with recognition result input manager unit 6, administrative unit 6 adopts supervisory computer, administrative unit is finished identification with the code identification unit, directly export the bin sign indicating number of letter sorting machine, and the coding that will refuse to know produces the position signalling of this coding, enter complement code processing unit 7, this complement code processing unit can utilize above-mentioned output computer.The position signalling that complement code processing unit receiving management unit is produced, from the code storage unit, obtain the gray scale image of this relevant position, and be sent to complement code platform 8, it links to each other with described coding processing unit, it comprises gray scale image display unit that shows and the input unit that is used to import the represented coding of this gray scale image to described complement code processing unit output, can adopt screen complement code platform here, it will be refused to know number and be apparent on the display device, the operator keys in correct number in view of the above, and the result that will key in delivers to administrative unit by communication interface 9 with the complement code result.Administrative unit is inserted its corresponding position of place letter according to the coding that the operator is keyed in, and exports the bin sign indicating number of six postcodes and letter sorting machine.
