Postal nine minutes mechanism The invention relates to postal matter nine minutes apparatus using that, more specifically, which makes it possible to simplify the system by identifying the mail item by using the feature information of the postal image and reduce the maintenance costs, the postal image feature on the mail item nine minutes device.
Looking at the domestic mail delivery system, separate from the delivery shipped distinction is made in the postal mail jipjungguk, where nine minutes mailing process by using a ZIP code as described in the mail being processed by an automated mail classification. Deliverymen Circuit in accordance with a predetermined path within the mail delivery area when delivery of mail and to deliver the mail, and this path is called a baedalsun.
Deliverymen called nine minutes fairway this process to sort mail in order to baedalsun of mail prior to delivery of postal water. On the other hand, it is referred to as fairway sorter machine to sort the mail item in the sequence shown in baedalsun. Unlike existing group fairway nine minutes of mail groups and nine minutes to complete the double over nine minutes fairway classified through the mail operation, array of procedures is based on the principle of radix sort algorithm.
Mails that were made in the process of nine minutes ZIP jipjungguk is contrary inde process classified into different bundles defined mail, mail fairway nine minutes the process is different in that it is the process of sorting the mail in a series of predetermined sequence. Another difference of nine minutes tile-based mail fairway nine minutes distinction mailing group that is primarily that, while being separated by a zip code, a sort can be precisely group fairway nine minutes to read address information, postal address.
Thus, due to features such as the automation of mail order nine minutes per fairway mail delivery address in the nation, and needs to be assigned a unique number, a unique number such as baedaljeom code or address code.
Therefore, it was an effective alternative to the current system, to adopt a barcode if you want to achieve the fairway nine minutes working group to leverage traditional mail segment. This is the whole address reading process by printing a bar code on the mail with the address read during the first mailing nine minutes operation, and the second mailing nine minutes obtaining the address information is read prior to reading a printed barcode during operation is limited to one to.
In this case, call the barcode information is printed on the mailing that mail ID. Postal nine minutes apparatus using a conventional bar code technology, postal nine minutes mechanism, also see Fig. Copper jakye cases to distinguish fairway mail by the conventional bar code reading and printing techniques are as follows. After the first nine minutes of the second mail mailing nine minutes step is completed, the operator then collect the mail from the mail load compartment in a specific order, and re-introduced a mechanism to collect mail on postal nine minutes to start the second stage mailings nine minutes.
Two if the second postal matter nine minutes mail is input in the step, the control member postal nine minutes obtain a mail serial number from the bar code reading section of the mechanical portion and the first mail item nine minutes memory using a mail serial number, an address code that was saved at step obtained from the apparatus, and determines a destination address corresponding to the load compartment, depending on fairway code plan, and the subsequent operation is the postal matter nine minutes and proceeds in the same manner as in the first nine minutes mail steps: In summary, the process fairway nine minutes using a conventional bar code as described above, first, print nine minutes in the mail process mail ID with the address read by the bar code, and stores the read address results for mail ID in the storage device.
Second, since the postal matters are to nine minutes to process without reading the address reads the mail ID barcode obtains the address of the read result from the storage device to the mail ID and separate the mail address according to the read result. However, the conventional method for identifying the mail item by using the bar code on the mail nine minutes apparatus as described above, there is the need for a separate bar code printing and reading device for the mailing nine minutes device, bar code printing apparatus as a black and white bar code printing apparatus or fluorescent use barcode printing device.
Black and white bar code printing apparatus has a problem in that the read out rate is significantly different depending on the material state and the printing state of the postal matter nameuro difficult to apply the fairway nine minutes problem of mail. On the other hand, the fluorescent bar code printing device tricky management of bar code printers methods that require a professional engineer with separate qualifications for the treatment and management of chemicals, such as fluorescent ink, keep on consumables such as fluorescent ink costs since there is a problem that even a high weighting for economic burden on the operation of the mail devices nine minutes.
The invention with be proposed by using the feature information of the postal image by identifying the mail, which will achieve such simplified systems, maintenance costs, fairway nine minutes improve the success rate, the postal image feature in order to solve the above problems to provide a mail nine minutes device they are an object.

The reason for giving a mail serial number from control unit to all the mail being conveyed along a mail item transport path in a mail nine minutes mechanism part in real time to the mail location tracking unit of the controller that the mail is transferred tracking while the mail image processing unit , the address reading section , the postal image identification unit in, regardless of the mail item position on the conveying path of the postal matter because it does not have position information of a mail item in real time as set, and the first regardless of whether the first nine minutes mailing step or a second step after nine minutes of mail, because it requires a means for referring to the mail item.
On the other hand, the two will be described an operation of the control unit of the mail item in the second stage nine minutes second si mail classification , as follows. Mail location tracking unit and the mail serial number generator in the first mail item sensitive and the same operation as that in step, the identification number candidate generator is loading the mail item from the first postal matter nine minutes Step mail compartment using a loading results by estimating the second order of the mail in the mail inputted nine minutes step generates the image identification number of the candidate by the predetermined number.
Identification number candidate transmission unit transmits the image identification number candidate generated by the ID number candidate generator , the identification number candidate receiving portion of the postal image identifying unit , the identification number receiving receives the identification number determined by the postal image identification unit , the mail loading space determining unit searches the address reading result obtained in the first mail item nine minutes steps from the video-ID number to address the read result as a fairway nine minutes plan information used to determine whether mail item is to be separated by any loading compartment on the mail loading part , and the mail branch signal generator operates in the same manner as in the first nine minutes mail steps: As postal image processing unit as a postal image processing means is shown in Figure 6, the first postal image receiving unit , a serial number receiving unit , the postal image sequence number assigning unit , the postal image transmission unit , it comprises a first postal image binarization section , the postal image compression unit Referring to the basic operation of the postal image processing unit , a first postal image receiver ZIP nine minutes receive incoming mail images from the postal image obtaining unit of the mechanical portion , a serial number receiving unit receives receiving a mail serial number from a mail serial number transmission section of the controller , the postal image serial number assignment unit in consideration of the received sequence and the reception time of the postal image and a mail serial number, the postal image and the mail item sikimyeo the serial number one-to-one basis, the postal image transmission unit transmits a mail serial number and the mail address to the image reading section , the postal image identification unit , respectively.
At this time, it is possible to a data compression prior to sending the mail image in order to shorten the time of transmitting a postal image as the postal image processor , the address reading section or the postal image identification unit from, for this purpose postal image processing unit may include a first postal image binarization section , the postal image compression unit to the secondary.
Here, the first postal image binarization unit is a data length required for binary ingestion mail image by determining the pixel value of the postal image into black or white, and the postal image compression unit to transmit the mail image information to reduce, change to the compressed mail to the binarized image information expressing form.
Accordingly, the address reading section is additionally sent to the image may include a restoration unit , the postal image identifying unit is the ability to restore the mail image in the image feature extraction unit or the postal image the may include the ability to binary. Address reading means as an address reading section as shown in Figure 7, the second postal image receiving unit , the postal image restoring unit , a second postal image binarization section , an address area determination section , comprises a character string extraction unit , a character extracting unit , a character recognition section , address analysis section , a read result transmitting unit Referring to the operation of the address reading section , a second postal image receiving unit receives receiving the mail images from the postal image transmitting section of the postal image processor , the received mail video compression and binarization the case image "", "when the binarization is compressed in , the postal image and restoration unit restores through decompressed , and brightness for the postal image " If you do not do not go through the "binarization , the second postal image binarization is binarized through the unit After the process to is a conventional address, the read process, the address area determination section , a character string extraction unit , a character extracting unit , a character recognition section , address analysis section the address code is output through.
That is, the address area extracting unit includes an image of a portion in which the recipient address base from the postal image payment address image extracted, and the character string extraction unit extracts a character string image from the extracted recipient address image to If, character extraction unit extracts each character image from the character string image.
Then, the character recognition section reads out the individual character images by looking output a character code and a confidence value corresponding to a Hangul or English, number and address analysis section is a combination of a series of character codes and confidence values try to find the most suitable address code output from the address dictionary.
Reading result transmitting section transmits the address code output from the serial number and the mail address analysis section received with the reception when receiving mail from the mail video image processor , the control unit Figure 8 is one embodiment of the detailed construction, zip receive input mail images from the video processor , the postal image identification unit to identify the postal image as in Figure 2 of the postal image identification unit according to the invention a indicates the function.
Postal image identifying means as the postal image identification unit , as shown in Fig. Operation of the postal image identification unit operates differently when the second mail item when separated from the first postal matter separated.
First, the first will be described an operation of the second postal matter nine minutes step claim when one postal matter sensitive ZIP image identification unit in the third postal image receiving the postal image transmission section of the postal image processor , mail serial number, the postal image mail receive receives the postal image on which the serial number has been assigned, the image feature extraction unit extracts the characteristic information that can identify the postal image from the postal image, image feature registration unit from stores the serial number and the image feature information of the image on the video mail feature store.
At this time, the mail reason to limit the search to the image feature information and limited to image identification number candidate in an image identification unit geotinde to shorten the search time required to select the image feature information, search of the image feature information If the limit is too much to be affected in the double-feed problems caused by mechanical failure or loss of mail due to the negligence of the operator.
Thus, the postal nine minutes mechanism , the mail sorting operation speed, the mail to be image identification number candidate generated by the frequency of occurrence of double-feed, consider the loss costs for lost problem of mail by the identification number candidate generator of the appropriate together crystal is preferable to, when the postal matter sorting operation speed of the postal nine minutes device for example 30, barrel and out a double feed occurrence frequency is 0.
At this time, when using the postal image reading characteristics, such as PO, and AR, the implement some functions of the address reading section , the image feature extraction unit , generate the address read process from the address reading section it is necessary to transmit the result mail to the image identification unit Image feature comparison unit compares the value of each feature extracted from the image feature extraction unit and the image feature information for each identification number candidates.
At this time, the comparison between the characteristics of the comparison with the vector type among the characteristic of the scalar type and outputs a distance value between the feature corresponding computed arithmetically by the Euclidean distance calculation, a numeric string distance comparison distance value between the following: Distance comparison between the different strings as compared to the AR-dimensional distance between the vector of the CP, such as may employ conventional dynamic matching algorithm in one embodiment.
Thus, each feature comparison value image feature distance value is converted to a scalar value, with the calculation method may select the following Equation 2 in a single embodiment. Here, W i indicates a weight for each image feature, and the distance, C i denotes a value for each image feature distance calculated above.
Identification number selecting unit , a total image feature distance D is the smallest calculated to output the identification number of the image feature, the smallest total image feature distance D if the value is beforehand is greater than the given threshold value T have the do not display the image identification number can dismiss any candidate identification number.
Therefore, the mail item loaded in the two spaces determiner is the mail is not output the image identification number in or not output the correct address code in the address reading section , the postal code identifying section ZIP nine minutes mechanism of it it is preferable to reject the mail to be separated by loading compartment provided on the mail item loading section Here, ceil x indicates the smallest integer not less than x, and, log x, y denotes the logarithm of x to y for the radix.
Referring to the characteristics of the radix sort algorithm using a fairway nine minutes mail process illustrated in FIG. At this time, the sort order of the mail item in the first delivery address for the convenience of calculation are intended to mark zero. On the other hand, the total number of baedaljeom in Figure 10 DP 25, when the total number NP of the normal loading compartment is assumed to be 5, the required postal nine minutes job number TP is a calculation example of "" in FIG.
That is, the input mail item indicated from 6 to 42 5 can be found for each separated by the first mail item Category 2 times the loading compartment in step, the second step in the mailing nine minutes loading compartment 4.
In the same process, look at the number system Pental, the first in the second mailing nine minutes step and separating the mail by the digit value of 15 for the number of mail sorting order, second mailing nine minutes steps based on the digit values of 10 5 as to separate mail is the same result.
Which loading of the ID number candidate generator , mail item identification number if the principle of determining the candidates described with reference to the explanatory diagram of Figure 10, the mail loading section with respect to all mail, separated from the first postal matter nine minutes steps by checking whether the loaded column in the mail location tracking unit , the first can be predicted the final state of the second mail item coded results , whereby after the first nine minutes mail is mail collected result is also calculated.
Therefore, assuming that an error such as double feeding mistakes or mail input of the worker does not occur after the first mailing distinct prediction mail order mail collection results and two mailings in the second mailing nine minutes steps in order to match, because the identification number candidate generator outputs a list of serial numbers for the front and rear of the N pieces of a predetermined input current postal mail.
In one example, the candidate number N as this is set to 5, when the predetermined current input mail item assumed to mail indicated by "" in Fig.
The method of the present invention as described above may be stored in a form that is implemented as a program in a computer-readable recording medium a CD-ROM, RAM, ROM, floppy disk, hard disk, optical magnetic disk, etc. Since the process can be easily implemented by those of ordinary skill in the art and will not be further described in detail. The present invention described in the above, the present invention are here to those of ordinary skill in the art can be various changes and modifications may be made without departing from the scope of the present invention, since the above-described embodiments and the accompanying It not limited by the drawings.
The present invention as described above, since without the use of a bar code printing machine identifies the mail by using the feature information of the postal image, since it requires a separate force for professional maintenance technician for the management of a bar code printing press, the holding of mail nine minutes device there is an effect that the maintenance easy.
In addition, the present invention is to simplify the mechanical construction of the mail nine minutes devices because they do not use bar code readers and bar code printing machine and and shorten the mail transport path and also the effect of allowing this reason to create a mail nine minutes device with a smaller size have.
