Method for processing large-size postal objects in a sorting installation
First Claim
1. A method of processing postal objects, in particular packets, in order to read a postal address (AD) automatically on each object, the method including a step of assistance by video-coding, said method comprising the following steps for each object:
- acquiring (10) a digital image of the object at a first level of resolution;
detecting (20) in said digital image of the object one or more zones of interest (ZI) of the image each apparently containing a postal address;
applying an automatic address recognition algorithm to each detected zone of interest in order to extract a postal address (AD) of said object; and
if the automatic address recognition step fails, displaying each zone of interest (ZI) at a second level of resolution on a screen of a video-coding station on a screen context background (F) representative of said digital image of the object in order to enable an operator to perform semi-automatic processing (50) to read the postal address (AD) of said object, wherein the screen context background is displayed on the screen at a third level of resolution that is lower than said second level of resolution.

Abstract
The method of processing postal objects of large size in order to read automatically a postal address (AD) on each object consists in acquiring a digital image of each object at a certain level of resolution; in detecting in the image one or more zones of interest (ZI) apparently containing a postal address; in performing automatic address recognition on each zone of interest in order to extract a postal address (AD) of the object, and in the event of the automatic address recogition failing, in displaying each zone of interest (ZI) on a screen so that a video-coding operator can read the postal address (AD) of the object. Each zone of interest (ZI) is displayed on the screen on a screen context background (F) that is representative of the object but at a level of resolution that is lower than the level of resolution of the digital image and the zone of interest. In this way, the video-coding operator has an overall view of the detected zones of interest, thus making it easier to read the postal address of the object.
