Portal with RFID tag reader and object recognition functionality, and method of utilizing same
First Claim
1. An object recognition system for identifying at least one object in a defined space, the system comprising:
- at least one radio-frequency identification tag (RFID) reader disposed in a position relative to a defined space to effectively read an RFID tag in the defined space and output an RFID signal representing information on the RFID tag;
at least one 3-dimensional object (3-D) recognition assembly disposed in a position relative to the defined space to capture an image of an object in the defined space and output an image signal representing the image of the object; and
a processor coupled to the at least one RFID reader and the at least one 3-D recognition assembly;
wherein the processor is configured to receive and process the RFID signal, to receive and process the image signal, and to determine whether the information on the RFID tag relates to the object in the image and if so, then to confirm the information on the RFID tag.

Abstract
An RFID/object recognition system monitors the passage of an object through a portal into a space. An RFID reader adjacent the portal communicates with an RFID tag within a preselected distance from the RFID reader. A data processor processes data from the RFID reader. A 3-dimensional scanner has an RGB camera and a depth sensor with an infrared laser projector and a monochrome CMOS sensor. An infrared laser controller is electronically coupled with the infrared laser projector, and a monochrome CMOS processor is electronically coupled with the monochrome CMOS sensor. The infrared laser controller, monochrome CMOS processor, and RGB camera are electronically coupled with a processor. The RFID reader receives data from an RFID tag when an RFID-tagged object passes within the preselected distance from the RFID reader through the portal. The 3-dimensional object recognition assembly identifies where the RFID-tagged object is located within the defined space.

9. A method of correlating an object in a defined space to a radio-frequency identification (RFID) tag, the method comprising:
-
reading data from at least one RFID tag by an RFID tag reader disposed in a position relative to a defined space; obtaining a 3 dimensional (3-D) image of an object in the defined space; transmitting to at least one processor an RFID signal representing the data; transmitting the 3-D image to the at least one processor; processing the RFID signal and the image in the at least one processor; and comparing the processed RFID signal with the 3-D image to determine whether the information on the RFID tag relates to the object in the image and if so, then to confirm the information on the RFID tag. - View Dependent Claims (10, 11, 12, 13, 15, 17)
