Abstract

The invention relates to a method and a device for monitoring the transport of several objects, in particular postal items. Each item is each provided with a label of a destination address.
Each item passes at least once through a sorting system. This sorting system always generates an image of the object. By evaluating the image, the sorting system recognizes the destination address of the item. Each item is transported to the recognized destination address.
The sorting system examines each item that has passed through the sorting system within a predetermined period of time, depending on whether the object has at least one predetermined optically detectable property or not. For this purpose, the sorting system evaluates the image that has generated the sorting of the object.
The sorting system is connected to a database. The sorter stores an image of an item in the database if and only if the item has the property. The images stored in the database are evaluated according to a predetermined evaluation criterion.

Description

  • The invention relates to a method and a device for monitoring the transport of several objects, in particular postal items.
  • Out EP 1345181 A2 For example, a method having the features of the preamble of claim 1 and an apparatus having the features of the preamble of claim 13 are known. The items are there mail, which are each provided with a delivery address. A sorting system generates an image of each mailpiece and stores it in a database. Subsequently, the stored images are searched according to predetermined criteria to determine certain images. Evaluations are carried out for the images determined in this way.
  • This method has the disadvantage that very large amounts of data have to be processed. In Germany, several dozen million postal items are carried per day. In order to examine a single image of a mail item, often one second of computation time is required. The end EP 1345181 A2 known method thus requires u. U. much computing time.
  • The invention has for its object to provide a method having the features of the preamble of claim 1 and an apparatus having the features of the preamble of claim 13, which is still manageable even with very many objects to be transported.
  • The object is achieved by a method having the features of claim 1 and an apparatus having the features of claim 13. Advantageous embodiments are specified in the subclaims.
  • The method monitors the transportation of multiple items. Each item is each provided with a label of a destination address.
  • Each item passes at least once through a sorting system. This sorting system always generates an image of the object. By evaluating the image, the sorting system recognizes the destination address of the item. Each item is transported to the recognized destination address.
  • The sorting system examines each item that has passed through the sorting system within a predetermined period of time, depending on whether the object has at least one predetermined optically detectable property or not. For this purpose, the sorting system evaluates the image that has generated the sorting of the object.
  • The sorting system is connected to a database. The sorter stores an image of an item in the database if and only if the item has the property. The images stored in the database are evaluated according to a predetermined evaluation criterion.
  • According to the invention only images of such objects are stored, which have a certain property. This ensures that only the images of interest are stored, instead of first store all images and then retrieve the interesting later.
  • The process can be carried out completely offline, without the transport of the objects is affected or impaired.
  • Preferably, several evaluations are carried out in parallel. Each evaluation provides to store those images of objects each having a certain property. Each selected image additionally stores a label of this property. This makes it possible to differentiate between different evaluations.
  • In the following the invention will be described with reference to an embodiment.
  • In the exemplary embodiment, the items to be transported and examined are mail items. Each postal item is provided with details of the delivery address. The delivery address preferably specifies the recipient as well as the street and house number or a mailbox or a compartment in a parcel compartment system and a location.
  • The transport is carried out with the help of several sorting systems of a transporter. The transport of a mailing begins in a place of delivery, z. B. a post office or a mailbox. First, the mail item goes through a sorting system for the first time, namely the one which is responsible for the place of delivery. The sorting system recognizes the delivery address and saves it between. The delivery address is assigned to a delivery area, z. The territory of a delivery post office. For example, the sorting system prints a bar pattern onto the mailpiece, which codes the delivery address.
  • For the delivery area and thus for the delivery address is also a sorting system responsible. The mail item goes through this second sorting system. Here, the second sorting system determines the buffered delivery address and causes the item of mail to be transported to the delivery area.
  • In the exemplary embodiment, both the first and the second sorting system each generate an image of a surface of each mail item that passes through the respective sorting system. This image contains an image of the delivery address with which the mailpiece is provided. The first sorting system has an image management system ("IMS"). This IMS performs the following steps automatically:
    • The IMS controls the image acquisition systems, e.g. As cameras to which produce the images of the mail.
    • The IMS distributes the generated images to the image evaluation systems, which attempt to automatically recognize the respective delivery address via "optical character recognition".
    • The IMS determines for which images the image evaluation systems were unable to recognize the delivery addresses automatically and forwards these images to video coding stations. At the video coding stations, the editors evaluate the images manually and manually enter information about the delivery address. B. via a keyboard and / or by voice.
    • For each mail item, the IMS determines which delivery address the image evaluation systems or the video coding stations have determined, and transmits this reading result to the sorting system.
  • An evaluation period is specified. All mail items that are transported within this evaluation period are to be examined to see if they have a predetermined characteristic. All mail items with the property transported in the evaluation period are to be evaluated.
  • According to the invention, the IMS additionally comprises a selection filter. The second sorting system also includes a selection filter in the exemplary embodiment. This selection filter is a software module that is preferably integrated as a "plug-in" into the IMS. The selection filter receives as input value an image of a mail item. The selection filter uses methods of image processing to determine whether or not the mail item from which the image originates has a predetermined characteristic. The selection filter preferably provides a "1" if the mailpiece has the property and a "0" if the mailpiece does not have the property.
  • The selection filter does not interfere with the above processing of the images executing the IMS just described. This does not affect the selection filter the work of the IMS and the image acquisition systems, image evaluation systems and video coding stations.
  • Methods of image processing and automatic recognition of patterns in computer-accessible images are, for. B. from the following publications:
  • The same selection filter is applied to all images to be examined within the evaluation period. Preferably, all sorting systems of the transporter apply the same selection filter, so that all mail items that pass through at least one of the sorting systems are examined by the same selection filters, regardless of which sorting systems they pass through. The fact that different sorting systems use the same selection filter is preferably achieved by each of these selection filters being a copy of the same original software module. It is also possible that each sorting system has the same selection filter and this a selection filter is stored on a central computer. Each sorting system sends a call to the central computer, which activates the selection filter. The result ("1" or "0") is transmitted to the requesting sorting system.
  • All sorting systems of the transporter are connected to a central evaluation database for images. Whenever the selection filter of a sorting system provides a "1" for an image of a mail item, the image is stored in the central evaluation database. If the selection filter returns a "0", the image will not be saved in the central evaluation database. The respective mail item then does not have the predetermined property.
  • As a rule, only a small fraction of the mail items that pass through the sorting systems in the evaluation period have the predetermined property. Therefore, only a fraction of all images are stored in the central evaluation database, and only this fraction is to be analyzed later.
  • Preferably, a copy of the image is stored in the central evaluation database. The image is preferably stored in the data format which the IMS supplies, for example JPEG, TIF or run-length coding. The images can be in particular gray-tone images or color images or even binary images.
  • In one embodiment, the selected images are compressed prior to storage to save storage space. However, information may be lost during compression, for example because the compressed images have a lower resolution than the original images.
  • It should be possible for the selected images to be evaluated according to any criteria - even those criteria that are subsequently defined. Therefore, the selected images are preferably not compressed before being stored in the central evaluation database. This avoids loss of data, pixels or resolution.
  • Preferably, the selection filter is provided with an identifier. For example, this identifier describes the property for whose presence or absence the selection filter examines an image. A selected image is stored in the central evaluation database together with a description. This description includes the identifier of the selection filter that selected the image.
  • The identifier of the selection filter is preferably stored because, in a preferred embodiment, a plurality of selection filters are performed in parallel. This is described for the case of two selection filters AF-1 and AF-2.
  • The selection filter AF-1 examines an image of a mail item to determine whether the mail item has a predetermined property E-1 or not. The selection filter AF-2 examines an image of a mail item to determine whether the mail item has a predetermined property E-2 or not. The selection filter AF-1 is used in a predetermined evaluation period AZ-1, the selection filter AF-2 in a predetermined evaluation period AZ-2. The two evaluation periods AZ-1 and AZ-2 overlap. Because each image is stored with a description containing an identifier of the selection filter, it is possible to determine which property the item of mail from which this image originated and to which selection filter that image is selected. It is possible that a mail item has both properties E-1 and E-2.
  • Preferably, the description with which the image is stored additionally includes the delivery address of the postal item - or at least the recognized part of the delivery address, e.g. For example, the postcode. This delivery address was determined as described above by an image evaluation system or a video coding station and delivered to the IMS. Therefore, this delivery address is present when the selection filter selects the image and the image is therefore stored in the central evaluation database.
  • The images stored in the central evaluation database are evaluated according to a predetermined evaluation criterion. This evaluation can take place at any time, eg. B. after the delivery of all mail items from which these images come. The evaluation can also begin during the evaluation period.
  • In order to carry out an evaluation, it is specified which property distinguishes the mailpieces to be analyzed from all other transported mailpieces. For this purpose, the identifier of this property and thus the identifier of that selection filter which examines images for the presence or absence of this property are specified. Automatically, all images whose description contains this identifier are selected in the central evaluation database.
  • Preferably, the selected images are subsequently evaluated by an analysis filter. This analysis filter receives as input value the set of selected images, ie the images of mail items with the given property. The analysis filter delivers the analysis result. For example, the analysis filter returns at least one of the following results:
    • the number of selected images and thus the number of those mail items which have the given property,
    • a histogram showing a statistical distribution of a parameter of the selected mailpieces. This parameter is, for example, the respective location or postal code of the delivery address or the addressee or also the respective transport duration of the mailpiece or the spatial distribution of delivery points in a region.
  • Preferably, the analysis filter outputs the analysis result in the form of an XML file. This embodiment makes it possible to easily process the analysis result further.
  • In the following, some applications of the invention will be described by way of example.
  • In a first application, it should be determined how long the transport of a mailpiece takes on average. For this purpose, a sample with z. B. generated and transported 1,000 postal items. Each mail item is delivered to a post office and marked there. The mail item passes through two sorting systems as described above and is delivered by a delivery agent.
  • Each postal item in the sample will be marked in the post office. This mark includes a optically detectable feature. This feature is a two-dimensional code in this application, ie a matrix code. In this matrix code the information is stored in coded form, when and in which post office this mailing was abandoned. Furthermore, the matrix code comprises an identifier for this mail item. This identifier distinguishes the mail item from all other mailpieces in the sample. The matrix code is designed such that it is printed only on the mail pieces of the random sample, but not on other mail items that the transporter transports.
  • The invention saves the need to provide mail items with identifiers that distinguishes the mail item from all other mailpieces that are to be transported by the conveyor during the evaluation period. As stated above, tens of millions of postal items are transported daily in Germany. Therefore, such an identifier would be very long and expensive to handle. The space on a mailing might not be enough to apply the matrix code. The sample consists of z. B. 1,000 postal items. The identification of the mail item need only distinguish 1,000 mailpieces, which is achieved with a sequence of four digits or ten bits.
  • The property of the mailing in this application is the presence of a tag with a matrix code that is used only for the sample. The selection filter examines whether an image of a mail item contains an image of such a matrix code.
  • If the selection filter of a sorting system has determined that an image of a mail item has an image of such a matrix code, the time at which this mail item has passed through the sorting system is additionally measured. The description of the image, which is stored together with the image in the central evaluation database, additionally includes this time in addition to the identifier of the selection filter.
  • In addition, each sorting system of the transporter is provided with an identifier. This identifier differentiates the sorting system from all other sorting systems of the carrier. The stored description of the image additionally includes an identifier of the sorting system that has generated the image.
  • Each mail item in the sample goes through a sorting system at least twice. If the mail can not be delivered and z. B. is sent back to the sender or to another predetermined substitute delivery address, so it goes through a sorting system even more frequently. In the central evaluation database, therefore, at least two images of each mail item of the random sample are stored.
  • In order to determine the average duration of mailpieces in the sample, all images that have an identifier of the selected selection filter are first selected. The analysis filter determines the matrix code in each selected image and decodes it. This determines the analysis filter
    • the identifier of the item of mail that distinguishes that item from all other items in the sample,
    • in which post office this mailing was delivered and
    • the time at which this mailing was delivered to this post office.
  • The stored description of the image is automatically taken by the analysis filter at which time the item of mail has passed through the sorting system which has produced this image. With the information just described, the way of the mailing can be traced to the delivery address.
  • For each postal item of the random sample, the analysis filter has at least three points in time:
    • the time at which this mailing was delivered to this post office,
    • the time at which this item of mail has passed through a sorting system for the first time, and
    • the time at which this mailing has passed through a sorting plant for the second time.
  • The analysis filter generates a statistical statement about the transport runtimes from this information. For example, the analysis filter generates two histograms that show the statistical distribution of the following two parameters:
    • the time span between the delivery of a mail item and the time at which this item of mail has passed through a sorting system for the first time, and
    • the time interval between the delivery of a mail item and the time at which this item of mail has passed through a sorting system for the second time.
  • In one embodiment, additional statistical evaluations are made for those mail items that have been delivered to certain preselected post offices or that have passed through certain sorting installations.
  • In a second application, it should be determined to which addressee a particular sender X sends mail within a predetermined evaluation period. This evaluation is carried out for police purposes, for example, or to initiate advertising measures. Of course, legal requirements for data protection must be observed.
  • In this second application, the characteristic of a mailing is the feature that the mailpiece originates from sender X. The sender provides the postal items he sends, with sender details, eg. B. with a specific logo and / or a certain lettering and / or with his own address. The selection filter determines whether in an image a mailing this logo / lettering / the address of X occurs. If this is the case, then the selection filter delivers a "1", otherwise a "0".
  • Each image of a mail item from sender X is stored together with a description in the central evaluation database. This description includes the delivery address that has recognized the sorting system through which the mailpiece is running for the first time. In the evaluation, the analysis filter "collects" these delivery addresses. For example, it generates statistical statements about parameters of these delivery addresses. B. the delivery place.
  • In a third application, it should be checked whether a major customer G of the transporter has correctly paid for the transport of postal items. The large customer G uses a franking machine ("postage meter"), which imprints a franking mark on every postal item that G sends. This franking mark takes the place of a stamp. The franking machine registers how many postal items of G has printed the franking machine. The major customer G pays to the transporter.
  • The franking machine is identified by an identifier, eg. B. by a four-digit number marked. This identifier distinguishes the franking machine from all other franking machines that are registered with the carrier.
  • The transporter wants to check whether the information on the franking marks which the franking machine transmits to the transporter and for which the major customer pays, is the transport charge to be paid for the mail pieces actually franked by that franking machine. In particular, it should be checked whether the major customer pays correctly, whether there are manipulation attempts or whether a third party unauthorizedly uses the identifier of the franking machine for its own mailings.
  • The property of a mail item is the presence of a franking mark with this identifier of the franking machine used by G. In this application, only one image of every mail item G is sent is needed. Preferably, the sorting system which recognizes the delivery address on a mailpiece of G additionally generates the image of this mailpiece and stores it in the central evaluation database.
  • The selection filter of this sorting system examines whether the image of a mailpiece contains an image of a franking mark (and not, for example, an image of a stamp) and whether in this image of the franking mark the predetermined identifier of the franking machine of G is contained.
  • In the analysis, the analysis filter in the simplest case counts how many mail items the selection filter has selected. This measured number is compared with information from the major customer.
  • In a further development of this third application, the target forwarding charge for each mail item is also determined by the major customer G. The sorting system which determines the delivery address of a mail item of G additionally measures those parameters which are included in the determination of the transportation charge. As a rule, these are the size and / or the weight of the mail item. The frequency of delivery regions can also influence the respective transport fee. The description, which stores the sorting system together with the image of a mail item of G in the central evaluation database, additionally comprises these measured parameters of the mailpiece.
  • The analysis filter reads the description with the measured parameters from the central evaluation database. With the aid of these parameters, he calculates the target forwarding charge of each mail item which G has transported by the transporter during the evaluation period. From this, the analysis filter calculates a total target delivery fee for all mail items that G has transported by the carrier during the evaluation period. This total target fare is calculated with the transport fee, the G actually for the Postage meter paid in the evaluation period compared. If G has paid too little, the transporter can prove the difference. As additional proof, the transporter can use the stored images as well as the measured parameters of all G's mail. With this information, the transporter is able to prove what total target fare G would have had to pay. In particular, with the help of the images it is easier to check whether G has manipulated himself or a third person has misused the ID of the franking machine of G.
  • In a fourth application, the items are pieces of baggage containing passengers' items. The sorting system takes the form of a baggage handling system at an airport. This baggage handling system includes a reader that transilluminates the items of baggage in order to detect objects in the items of luggage that may not be transported at all or at least not in hand luggage. The reader generates an image of the objects in a piece of luggage. Security forces examine these images visually.
  • The property of a piece of luggage is the presence of objects of certain types in the piece of luggage. Objects of these types can be automatically recognized in the image. For example, all pieces of luggage are to be selected in which at least one weapon to be transported or a bottle with a liquid.
  • The selection filter examines each image of a piece of luggage to see if it contains the outline of an object of a desired type, e.g. B. the outline of a weapon or a bottle.
  • For example, in the analysis, the analysis filter counts how many such pieces of luggage the selection filter has detected. This number is compared with the results obtained by the security forces checking the baggage. The analysis filter also determines parameters of objects of the searched species. For example, it approximately determines how much liquid contained in a bottle in a piece of luggage. For this purpose, he evaluates the outline of a bottle in the image of the item of luggage.
