METHOD FOR SORTING POSTAL ITEMS INCLUDING AN OPTIMISED MANAGEMENT OF THE EXPLORATION SPACE OF ITEM SIGNATURES

摘要

The invention relates to a sorting method for the multiple-pass sorting of postal items in a sorting machine with accumulation sorting outlets, that comprises using an item identification technique by image signatures (V-id) derived from the postal items. The postal items are transferred into trays between two sorting passes. A match search between a current imprint during a second sorting pass and imprints generated during the first sorting pass is carried out in an exploration memory space containing a limited number of imprints. The optimisation of the size of the exploration space is obtained by combining, with the signatures and the trays, destination information (ST) indicative of the sorting outlets and time information (Ts, Hb) provided by a clock.
