Abstract

Systems and methods for identifying new radio frequency identification (RFID) tag events within a particular vicinity of an RFID reader are described. In various aspects, a processor causes image sensors to capture a first set and a second set of video images, where the first set depicts a first RFID tag environment and the second set depicts a second RFID tag environment. The first RFID tag environment is static without a person moving within the first RFID tag environment and the second RFID tag environment is active with at least one person moving within the second RFID tag environment. An environment database may be generated and updated with static analytic information and active analytic information based on the first set and second set of video images, respectively. The processor may determine a RFID tag event based upon the static analytic information and the active analytic information.

First claim

What is claimed is:

1. A point of sale (POS) system enhanced with one or more image sensors for identifying new radio frequency (RF) identification (RFID) tag events within a particular vicinity of an RFID reader, the POS system comprising one or more processors, the POS system configured to:
capture, with the one or more image sensors, a first set of one or more video images, the first set of video images captured at a first time and depicting a first RFID tag environment, the first RFID tag environment being static, wherein the first set of one or more video images does not depict a person moving within the first RFID tag environment, the first RFID tag environment associated with at least a portion of the particular vicinity of the RFID reader;
generate an environment database, the environment database including static analytic information determined from the first set of one or more video images and the RFID reader;
capture, with the one or more image sensors, a second set of one or more video images, the second set of video images captured at a second time and depicting a second RFID tag environment, the second RFID tag environment being active, wherein the second set of one or more video images depicts at least one person moving within the second RFID tag environment, the second RFID tag environment associated with the at least a portion of the particular vicinity of the RFID reader;
update the environment database, the environment database including active analytic information determined from the second set of one or more video images and the RFID reader; and
determine at least one RFID tag event based upon the static analytic information and the active analytic information.

2. The POS system of claim 1 further configured to, with the one or more processors, eliminate at least one false RFID tag event, the at least one false RFID tag event occurring at the second time within the particular vicinity of the RFID reader.

3. The POS system of claim 1 further configured to, with the one or more processors, update the environment database with additional analytic information determined from a third set of one or more video images and the RFID reader, wherein the third set of one or more video images are captured at a third time and depict a third RFID tag environment, the third RFID tag environment associated with the at least a portion of the particular vicinity of the RFID reader, and the third RFID tag environment being one of static or active.

4. The POS system of claim 1 , wherein the static analytic information includes the first set of one or more video images and a first set of RFID tag identifiers (IDs), the first set of RFID tag IDs associated with a first set of RFID tags of the first RFID tag environment, and wherein the active analytic information includes the second set of one or more video images and a second set of RFID tag identifiers (IDs), the second set of RFID tag IDs associated with a second set of RFID tags of the second RFID tag environment.

5. The POS system of claim 1 , wherein the at least one person is located within a POS lane, the at least one person associated with a product for purchase, the product for purchase associated with an RFID tag.

6. A point of sale (POS) method using with one or more image sensors and one or more processors for identifying new radio frequency (RF) identification (RFID) tag events within a particular vicinity of an RFID reader, the POS method comprising:
capturing, with the one or more image sensors, a first set of one or more video images, the first set of video images captured at a first time and depicting a first RFID tag environment, the first RFID tag environment being static, wherein the first set of one or more video images does not depict a person moving within the first RFID tag environment, the first RFID tag environment associated with at least a portion of the particular vicinity of the RFID reader;
generating an environment database, the environment database including static analytic information determined from the first set of one or more video images and the RFID reader;
capturing, with the one or more image sensors, a second set of one or more video images, the second set of video images captured at a second time and depicting a second RFID tag environment, the second RFID tag environment being active, wherein the second set of one or more video images depicts at least one person moving within the second RFID tag environment, the second RFID tag environment associated with the at least a portion of the particular vicinity of the RFID reader;
updating the environment database, the environment database including active analytic information determined from the second set of one or more video images and the RFID reader; and
determining at least one RFID tag event based upon the static analytic information and the active analytic information.

7. The POS method of claim 6 further comprising, via the one or more processors, eliminating at least one false RFID tag event, the at least one false RFID tag event occurring at the second time within the particular vicinity of the RFID reader.

8. The POS method of claim 6 further comprising, via the one or more processors, updating the environment database with additional analytic information determined from a third set of one or more video images and the RFID reader, wherein the third set of one or more video images are captured at a third time and depict a third RFID tag environment, the third RFID tag environment associated with the at least a portion of the particular vicinity of the RFID reader, and the third RFID tag environment being one of static or active.

9. The POS method of claim 6 , wherein the static analytic information includes the first set of one or more video images and a first set of RFID tag identifiers (IDs), the first set of RFID tag IDs associated with a first set of RFID tags of the first RFID tag environment, and wherein the active analytic information includes the second set of one or more video images and a second set of RFID tag identifiers (IDs), the second set of RFID tag IDs associated with a second set of RFID tags of the second RFID tag environment.

10. The POS method of claim 6 , wherein the at least one person is located within a POS lane, the at least one person associated with a product for purchase, the product for purchase associated with an RFID tag.
