AUTOMATIC ADDRESS EXTRACTOR

Abstract: A method and apparatus (10) for preparing forms used by the Postal Service in delivering certain types of mail (E). Each piece of such mail is conveyed past a camera or scanner (12) to obtain an image of the piece including the name of the sender and name and address of the recipient. The image is processed by an image processor (14) to locate the edge (C) of the piece at its upper left hand corner where sender information is located. A first line of information, usually the sender's name, is extracted from a sender information segment (S) of the envelope, and the first two lines of recipient information, usually the recipient's name and street address, are extracted and from a recipient's information segment (R) of the mail piece. These three lines of information are now transferred from the memory onto an appropriate postal form (F) with each line of information copied onto an appropriate portion of the form. The forms are sorted by zip code and carrier route so a carrier can pick-up the forms needed together with the mail carried on their route.

Description: AUTOMATIC ADDRESS EXTRACTOR Technical Field This invention relates to the processing of information on envelopes and similar pieces of mail, and more particularly, to a method of automatically extracting desired information from the piece of mail for use by a postal service in delivering the mail. The method and apparatus are also useful by other delivery services in delivering parcels of various types. Special delivery pieces of mail, for example, express mail envelopes, certified or registered letters, insured packages, and the like all require the postal service to fill out a form in which specific information as to the source, addressee, contents, etc. is included. Currently, a postal employee must manually complete the form, taking the necessary information off of the piece of mail and copying it onto the form. This is not only a time consuming process, but is prone to mistakes being made. The simple fact someone chooses to use special delivery to send a piece of mail means the contents are valuable, time critical, or both. Accordingly, the time it takes to complete the form, and the accuracy in transcribing the information has a significant impact for both the sender and recipient, as well as the perceived competency of the postal service. A process which not only speeds up the transfer of information from the piece of mail to the form but also increases the accuracy and completeness of the information transferred, increases the efficiency of the postal service and its perception as a provider of quality service by the public. Background Art Among the several objects of the present invention may be noted the provision of a process for acquiring specified information from a piece of mail and transferring the information to a form or receipt to be signed by the recipient; the provision of such a process in which the piece of mail is scanned by a scanner programmed to extract the desired information from the piece or by a camera from which an image is obtained for processing; the provision of such a process in which the scanner is further programmed to transfer the information onto the form; the provision of such a process in which portions of the information to be included on the form are identifiable at different locations of the piece and those locations are selectively scanned to acquire the appropriate information; the provision of such a process in which the information acquired by scanning the piece can be transferred to the form in either the same or a different order than that in which the information is obtained; the provision of such a process in which each piece of mail is conveyed past the scanner, or camera so the desired information can be obtained from the piece; the provision of such a process in which the extracted information can be sorted by zip code or street address, for example, so the form can be prepared in a manner conforming to a carrier's route; the provision of such a process in which the scanned information includes hand written information which is printed or in cursive, as well as typed or electronically printed information; the provision of such a process in which the materials scanned includes envelopes of various sizes and shapes, as well as parcels and packages of different sizes and shapes; and, the provision of such a process to improve the efficiency and accuracy in which the requisite information is obtained and transferred to an appropriate form or receipt which is required by the Postal Service for the delivery of specific types of mail. In accordance with the invention, generally stated, a method and apparatus are provided for facilitating the preparation of forms required by the Postal Service for the delivery of particular pieces of mail. The process first involves conveying each piece of such mail past a camera or scanner to obtain an image of the piece including the name of the sender and name and address of the recipient. The image is then processed by an image processor to locate the edges of the piece at its upper left hand corner where sender information is usually located. The first line of information, typically the sender's name, is then extracted and stored in a memory. An address block for the recipient is next located. The first two lines of information, usually representing the recipient's name and street address, are now extracted and stored in the memory. The three stored lines of information are then transferred from the memory onto an appropriate postal form with each line of information copied onto an appropriate portion of the form. The forms may be sorted by zip code, street address and carrier route so each carrier can pick-up the forms he or she will need together with the mail they carry that day on their route. Other objects and features will be in part apparent and in part pointed out hereinafter. Brief Description of the Drawings In the drawings, Figs. 1A-3 are representations of forms used by the United States Postal Service and which require name and address information of a recipient, Figs. 1A and IB respectively showing the front and sides of form 3813- P for the receipt of insured mail, and Figs. 2A and 2B respectively showing the front and back sides of form 3849 for mail requiring a signature of the recipient for delivery, and Fig. 3 form 3800 for receipt of certified mail; Figs. 4 and 5 represent envelopes with senders' and recipients' names and addresses, some names and addresses being handwritten, and others being printed or written in cursive; Fig. 6 is a simplified representation of one portion of the apparatus of the present invention; Fig. 7 is another simplified representation of the apparatus of the present invention; Fig. 8 illustrates the front of an envelope or label and where thereon sender and recipient information is typically found; Fig. 9 illustrates sender and recipient information obtained from the envelope of Fig. 4 and used to complete one of the forms shown in Figs. 1-3; Fig. 10 similarly illustrates the sender and recipient information obtained from the envelope of Fig. 5; and, Fig. 11 illustrates a completed form with sender and recipient information printed onto the form in the same form in which the information appears on the envelope. Corresponding reference characters indicate corresponding parts throughout the drawings. Best Mode for Carrying Out the Invention Referring to the drawings, apparatus and a method of the present invention is for use in extracting information from an envelope E or label L attached to a box or package K, and for using this information in filling out forms F used by the United States postal service or other delivery services. Referring to Figs. 1A-3, Figs. 1A-1B represent United States Postal Service (USPS) form 3813-P which must be completed when insured mail is delivered to a recipient. Figs. 2A-2B represent USPS form 3849 used as a receipt or reminder for mail delivery. Fig. 3 represents USPS form 3800 which is used for delivery of certified mail. In each instance, when a postal carrier delivers a piece of mail which falls into one of the categories with which the forms are associated, certain information must be completed. In particular, information about the sender and recipient must be filled in on the form. As previously discussed, carriers have heretofore had to manually complete these forms before leaving on their routes. In accordance with the present invention, this process is now automated, saving the carrier time, and reducing mistakes. Mail is sorted. It is sorted not only by the zip code of the recipient, but also as to the type of mail; insured, certified, etc. Mail also comes in various guises. Most mail is in the form of either envelopes E or flat pieces in which the names and addresses of the sender S and recipient R or inscribed on the front of the piece as shown in Fig. 8, or in the form of packages K to which a label L is attached. The label also includes the sender's and recipient's names and addresses. Referring to Fig. 10, it is conventional that certain information is placed on an envelope E, for example, in a particular format. As shown, postage P is usually placed in the upper right hand corner. Information S about a sender is usually placed in the upper left hand corner, and recipient information R in the center portion of the envelope. Although not shown, it will be understood that sender and recipient information included on a label is also usually in a prescribed format. Envelopes E and packages K are placed on a conveyor belt B which conveys the pieces from one station SI to another station S2. Apparatus 10 of the present invention includes a camera, scanner, or other imaging device 12 which is positioned above the conveyor belt. Mail pieces are placed on the conveyor belt with address information visible to the camera. As each mail piece passes beneath scanner 12, an image of the envelope or label is obtained by the camera and transmitted to a processor 14. It will be understood that the sender and recipient information S and R can appear in a variety of ways. In Fig. 4, for example, both the sender and recipient information appear in a block form which is produced by a typewriter or word processor. In Fig. 5, this information is produced in cursive as when the sender writes this information on the envelope or label. It will be further understood that there are a variety of combinations of the forms shown in this two figures. Importantly, processor 14 does not attempt to recognize or interpret the information on the face of the envelope or label. That is, the processor's function is locate those areas on an envelope or label where the pertinent sender and recipient information is located, so pertinent portions of that information can be reproduced on the appropriate form F. Typically, address information, whether the sender's or the recipient's includes a plurality of vertically arranged, horizontally extending lines in a first line of which the sender or recipient's name appears. The sender or recipient's street address is then set out in a second line which appears beneath the first line. The city, state, and zip code then appear in a third line beneath the first two; although, the zip code may sometimes be set out in a fourth line below the first three. For purposes of the present invention, processor 14 looks for the first line of the sender information S, and the first two lines of the recipient information. For purposes of completing a form F, it is only necessary that the sender's name be known. Also, since the mail is sorted by zip code prior to being placed on conveyor belt B, obtaining the zip code information is unnecessary. After scanner 12 has an image of a mail piece, the image is transmitted to processor 14. The processor processes the image to first locate the upper left hand corner C of the envelope. Once this is done, the processor can then place all the information contained in the image into an appropriate image framework. As shown in Fig. 8, the envelope can be divided into segments in which selected information should appear. Thus, the processor will treat the information in the upper left hand corner of the image as sender information S, information in the upper right corner as postage, and information in the middle portion of the image as recipient information R. Occasionally, information may appear on those portions of the envelope marked "OTHER" in Fig. 8. If the processor recognizes the sender and recipient information in their anticipated locations on the face of envelope E, the processor will recognize but disregard the information appearing in these other areas. As shown in Figs. 9 and 10, processor 14, once it has identified the relevant sender and recipient information blocks, treats the remainder of the envelope image as extraneous. The processor now copies the first line of information in the sender S information block and transfers the copied information to a form printer 16 in which the respective forms F shown in Figs. 1A-3 are queued. The form printer then prints the copied information into the correct location on the form. For example, Sender, Name is the first line on the back of form 3813-P; so, the copied information is printed on this line. Next, the processor copies the first line of information in the recipient R block and prints this information on the Sent To line at the top of the front page of the form. Finally, the processor copies the second, street address line in the recipient information block and transfers this information to the Street & No. line on the front page of the form. A completed form is shown in Fig. 11. If the forms are batch printed, they can then be sorted by a sorter 17 so all the forms needed by each carrier are individually available to the carrier. Those skilled in the art will recognize that it is immaterial as to the sequence in which the three lines of copied information are printed onto the form. Further, rather than printing a form each time an envelope is viewed by camera 12, the information can be stored in a memory 18 until all of the envelopes and packages have been scanned. The information is then transferred from the memory to the printer and the forms are prepared. This latter embodiment is indicated by the dashed line configuration in Fig. 7. Regardless of which method is used to print the forms, once the forms are completed, the mail carrier can pick-up the forms together with the mail for delivery along the mail route. In addition, if the carrier has a preferred route he or she takes to cover their route, processor 12 can be programmed with that information. Then, as the envelopes or parcels are scanned, the information obtained can first be sorted in accordance with the route information, so the forms F can be printed in the same sequence as the route is covered. The carrier is thus saved an additional step of having to sort the printed forms before beginning the route. What has been described is a process for acquiring specified information from a piece of mail. The mail piece can be an envelope or package and different sizes and shapes of each are accommodated by the process. Each piece is scanned by a scanner or camera programmed to extract desired information from the piece for transfer information onto an appropriate form. The requisite information can be found on different portions of the piece and the acquired information can be transferred to the form in both a different order and a different format than that in which it is included on the piece. The process allows the extracted information to be sorted, for example, by zip code or street address. The process allows information to be extracted whether found in hand written form, or in a typed or printed format. Use of the process improves the efficiency and accuracy in which the requisite information is obtained and used to complete an appropriate form. A separate form can be printed each time an envelope or package is viewed or scanned, or the pertinent information from each envelope is stored in a memory and the forms are batch run after all the parcels have been viewed. In view of the foregoing, it will be seen that the several objects of the invention are achieved and other advantageous results are obtained. As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
