Abstract

Systems and methods for data reading, which in one configuration is directed to an automated optical code data reader (5) in the form of a tunnel or portal scanner (100, 500) having an open architecture configured with front and rear inverted U-shaped arches (110, 120), a plurality cameras (some or most of which having multiple fields of view) (150, 160, 170, 180, 192 / 194, 250, 260, 270, 280, 300, 310, 320, 330) in each of the arches for reading the top five sides of an item (20) being passed by a conveyor (15 / 16) through a read region formed by the arches, and a bottom reader (130) including one or more cameras (410, 420) under the conveyor for reading a bottom side of the item through a gap (50) in the conveyors as the item is passed over the gap. Also disclosed are specific imaging schemes for providing effective views of the items with a minimum number of cameras.

Description

technical field [0001] The field of the disclosure relates to systems and methods for item inspection, and in some respects to retail inspection kiosks or other checkout kiosks that include data readers and other electronics (eg, package dispatch kiosks). The field of the present disclosure further relates generally to data reading devices, and more particularly to automated devices by which items are conveyed through the reading zone of a data reader, typically on a conveyor, for example by reading Optical code or RFID (Radio Frequency Identification) tags identify items by a data reader. Background technique [0002] Data reading devices are used to acquire data from optical codes or electronic tags (eg, RFID tags), or to identify items using image recognition. One common type of data reader device is an RFID reader. Another common data reader device is an optical code reader. Light codes usually contain a pattern of dark elements and light intervals. There are differe...
