Abstract
A system for reading package information includes an imaging system and a label decoding system. The imaging system captures an image of a package surface that includes a machine readable code such as a bar code and an alphanumeric destination address. The label decoding system locates and decodes the machine readable code and uses OCR techniques to read the destination address. The destination address is validated by comparing the decoded address to a database of valid addresses. If the decoded address is invalid, an image of the destination address is displayed on a workstation and an operator enters the correct address. The system forms a unified package record by combining the decoded bar code data and the correct destination address data. The unified package record is used for subsequently sorting and tracking the package and is stored in a database and applied to a label that is affixed to the package.
