Abstract

A package information capture system that provides dimensioning information about, and machine readable codes from, packages passing across a data capture point either singulated or non-singulated. The resulting data can be used to determine, for example, package dimensions, package coordinates, dimension confidence, package classification, and content and coordinates of the machine readable code. The dimensioning information is correlated with the machine readable code to form one record. Subsequent processes can access the record from all or part of the captured machine readable information to retrieve package dimension information.
