Abstract
Method and apparatus for reading dispatch addresses with postcodes The invention relates to a method and an apparatus for reading dispatch addresses with postcodes which identify the addresses up to part of a larger street or a few small streets, in the case of non-unambiguous read results of the OCR unit. If the street read by the OCR unit does not correspond to the street(s) or street region derived from the video-coded postcode, the following steps are carried out:
- inputting of one or two extraction codes which identify the distribution point, - repeated video coding of the postcode by a different operator than in the case of the first postcode video coding if, in the case of the comparison of the extraction code(s) with the postcode video-coded first, these do not match one another, -~comparison of the two video-coded postcodes, and if they correspond, the postcode situated on the dispatch is classified as incorrect.
- inputting of one or two extraction codes which identify the distribution point, - repeated video coding of the postcode by a different operator than in the case of the first postcode video coding if, in the case of the comparison of the extraction code(s) with the postcode video-coded first, these do not match one another, -~comparison of the two video-coded postcodes, and if they correspond, the postcode situated on the dispatch is classified as incorrect.
