Definitions

  • the present invention relates to a method for reading the addresses of programs according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 6.
  • OCR Automatic address reading
  • the detection rates of the automatic reading systems vary widely, it is necessary to support them by means of video coding devices.
  • the video images of the programs rejected by the OCR processor are manually encoded by video encoders at respective video encoders.
  • the entered addresses are converted by means of a directory into a sorting code.
  • OVS online video encoding
  • OVS The main problem with using OVS is that the time available is sufficient only for careful entry of the zip code (ZIP) or postal code (PC), unless unusually long delay lines are used.
  • the images of two programs are displayed simultaneously; one over the other.
  • the lower image is the active one, ie its data is encoded.
  • operators are able to encode the information on the lower image while already recording the address information from the upper image.
  • the upper image then becomes active and the process continues.
  • predictive coding it is possible to double operator productivity by completely overlapping cognitive and motor functions when encoding consecutive images.
  • extraction coding is based on specially designed rules that use a fixed-length code as the access key to an address directory.
  • the Royal Mail uses an extraction formula based on the first three and last two letters. Special rules need to be memorized by the operator to avoid redundant address information and to provide certain distinguishing features, e.g. To take into account directions, e.g. East, West or categories e.g. Street, Lane, Road.
  • Extraction coding despite its certain effectiveness, has some major disadvantages; especially complex extraction rules, which often require consideration of the end of a street name, while these components are usually written most unclearly.
  • complex extraction rules which often require consideration of the end of a street name, while these components are usually written most unclearly.
  • No. 4,632,252 has also disclosed a sorting system with a plurality of sorters, comprising the sorting section, image recording and OCR unit, and a plurality of coding stations.
  • the data rejected in the OCR units is assigned to the video encoders via a distribution unit.
  • the video-encoded data is then returned via the distribution unit to the sorters from which the rejected data originates.
  • the selection of the video coding stations is carried out so that the throughput is as high as possible and the coding stations are used as high and evenly as possible.
  • the invention specified in claims 1 and 6 is based on the object in an address reading system with a plurality of video encoding slots to reduce the video coding effort at given performance parameters.
  • the invention is based on the idea of making the request for actuating a confirmation key for each video coding station separately executable and, if necessary, assigning only the coding forces with higher error rates the requirement, since only with them a significant opportunity exists, by rechecking and pressing the Confirmation key to eliminate coding errors.
  • the error rate and the read rate of the video coding device and, for each coding force, the current individual error rate with and without actuation of the confirmation key are determined at fixed time intervals and stored in the job distribution device.
  • each coding force enters at its video coding station for identification a personal identifier, which is transmitted to the order distribution device.
  • FIG. 1 shows a schematic representation of an apparatus for carrying out the method.
  • An OCR Briefsortierer 100 consists of a feeder 110, which successively subtracts mail from a magazine 111 and transported at about 10 broadcasts per second to a high-resolution video scanner 120. Subsequently, the items are transported in a delay line 121.
  • the broadcasts usually have address information on their surface.
  • an evaluation of the address information of the images of the broadcasts obtained by the video scanner 120 takes place.
  • a barcode printer 150 is activated and the consignment is provided with a corresponding barcode for the subsequent sorting in sorting compartments 160.
  • the OCR processor 130 consists of one or more microprocessors 131 with associated memory 132 for storing images of the transmissions. Furthermore, the OCR processor 130 includes an address dictionary 134 with ZIP codes, city names and street names and possibly further address-related information. When evaluating the images containing address information, a feature-controlled reduction of the entry obtained from the address dictionary 134 ensues, so that a kind of sub-dictionary is generated. Credentials are assigned in individual entries, so that a number of data are generated from correctly recognized addresses during the evaluation.
  • the device also contains an order distribution device 170 as well as a number of video coding stations 200, which are directly connected to the order distribution device 170 or by a local network
  • LAN 171 are connected. If the OCR evaluation of an image was unsuccessful, this image is transferred from the OCR processor 130 to the job distribution device 170 and stored there in a database. On the one hand, the order distribution device 170 controls the TID bar code printer 151 and, on the other hand, sends the corresponding image to one of the video coding stations 200. The TID bar code printer 151 applies an identification code TID to the corresponding mail item, which makes it possible at a later time to use the evaluated address information physical
  • Link consignment The evaluation of the images takes place offline in this case, although in principle with a sufficiently long delay time and an online evaluation by video encoding is possible. In the latter case, the TID may also be used at a later time, i. if the video coding did not lead to a complete evaluation within a certain predetermined time, to which broadcasts are applied. After video coding, the respective result is verified using the address dictionary 134. If there is no match with an entry, the result is rejected.
  • the job dispatcher is connected to only one OCR letter sorter 100 with OCR processor 130.
  • OCR processor 130 the coupling is also possible with several OCR letter sorters.
  • the images generated in the video scanner 120 are transferred directly to the order distribution device 170 where they are stored in the database and distributed to the video coding stations 200.
  • the address dictionary 134 required for verification is then part of the order distribution device 170.
  • the error rate during video coding is determined at fixed intervals with and without pressing the confirmation key. This happens semi-automatically, e.g. In the case of rejected (unsuccessful verification based on the address dictionary) encodings in a recoding, it is ascertained whether the cause is an input error of the coding force or a wrong addressing by the sender or a faulty entry in the address dictionary. Over a fixed period of time (see Table 1) or a fixed number of codes, the error rate is statistically determined.
  • Table 1 shows for 6 encoders the determination of the individual errors from the number of encodings without and with actuation of a confirmation key in a certain time and the number of input errors and the determination of the total errors of the video coding apparatus with all the video encoders.
  • the encoder force C should use the confirmation key because it has the highest potential for coding error avoidance. If more errors are to be avoided, coding force F with the second highest error rate would additionally have to be confirmed. On the other hand, it can be seen that with the encoders B and D no error reduction can be achieved by using the confirmation key, i. the result would be just a throughput reduction.
  • the individual coding error rates are always kept up to date and stored in a coding profile database.

Abstract

L’invention consiste à configurer la demande d’actionnement d’une touche de confirmation pour chaque espace de codage vidéo de manière à ce qu'elle se déroule séparément et à affecter la demande selon les besoins seulement aux degrés de codage présentant des taux d’erreur supérieurs, dans la mesure où ils sont les seuls à constituer une chance significative de supprimer les erreurs de codage grâce à un contrôle répété et à l’actionnement de la touche de confirmation. On détermine ainsi à intervalles réguliers le taux d’erreur et la fréquence de lecture du dispositif de codage vidéo et pour chaque degré de codage le taux d’erreur individuel actuel avec et sans actionnement de la touche de confirmation et on les mémorise dans le système de répartition des tâches.
