Abstract
A system and method for enhanced monitoring and sorting of delivery items, such as packages, which are moved and sorted via a delivery service conveyor device. Conventional systems may employ photocells, which detect interrupted light beams, to identify packages or delivery items along a conveyor path. The present system and method enhances photocell function by adding image detection and analysis to the mail path; and further by modifying the photocell signals to the sorter/conveyor control. The present sensing system is located in the same area on the transport as the photocell, and uses a camera to capture an image of the mail path in the photocell area. The system and method then analyzes a package image to formulate a more accurate item detection signal, based on photocell data and image data, for input to the sorter/conveyor control system.
