Postal object e.g. parcel, treating method for postal object sorting machine, involves detecting whether outer surface of object is of plastic material and has uneven base, to detect whether surface is printable or non-printable surface

摘要

The method involves measuring for a postal object, a physical quantity for detecting whether an outer surface of the postal object is made of plastic material, using a gloss detector. A digital image of the surface is formed and is processed to detect whether the surface has an uneven base. The surface is detected as a printable surface or a non-printable surface, based on the result of the two detection. An independent claim is also included for a postal objects sorting machine having an automatic address recognition module, and adapted for implementing a postal object treating method.
