Abstract

A method of determining a revised position of a tag, comprising the steps of determining a first parameter associated with the tag based on a first set of data from a first sensor, determining a second parameter associated with an object based on a second set of data from a second sensor, determining whether the first parameter corresponds to the second parameter, and if the first parameter corresponds to the second parameter, determining the revised position of the tag based on the second set of data.

Claims

1. A method of determining a revised position of a tag, comprising the steps of:

(a) determining a first parameter associated with the tag based on a first set of data from a first sensor;

(b) determining a second parameter associated with an object based on a second set of data from a second sensor;

(c) determining whether the first parameter corresponds to the second parameter; and

(d) if the first parameter corresponds to the second parameter, determining the revised position of the tag based on the second set of data.

2. The method of claim 1 wherein the first set of data comprises the angle of the tag relative to a tag reader and/or the signal strength of a signal sensed by the tag reader.

3. The method of claim 1 wherein the second sensor is arranged to capture at least one image of a region, wherein the object is within the region.

4. The method of claim 1 wherein the second parameter comprises data indicative of a position of the object.

5. The method of claim 1 wherein the step of determining the second parameter associated with the object includes determining the first object position.

6. The method of claim 1 wherein the step of determining whether the first parameter corresponds to the second parameter comprises determining whether the tag position corresponds to the object position.

7. The method of claim 6 wherein the step of determining whether the tag position corresponds to the object position comprises determining whether the range of tag position values, at least partially, coincides with the range of object position values.

8. The method of claim 1 wherein the step of determining whether the first parameter corresponds to the second parameter further comprised determining whether the tag velocity and/or direction of tag velocity corresponds to the object velocity and/or direction of object velocity.

9. The method of claim 8 wherein the step of determining whether the tag velocity corresponds to the object velocity comprises determining whether the range of tag velocity values, at least partially, coincides with the range of object velocity values.

10. The method of claim 1 further including the step of determining whether the revised position of the tag is at least one of:

outside a first defined zone and inside a second defined zone.

11. The method of claim 1 wherein a plurality of units each comprise a housing, each unit housing at least one of:

one of a plurality of first sensors and one of a plurality of second sensors;

wherein, the step of determining the first parameter may comprise determining the first parameter based on the first set of data from the first sensor and from a further first set of data from a further first sensor; and

the step of determining the second parameter may comprise determining the second parameter based on the second set of data from the second sensor and from a further second set of data from a further second sensor.

12. A monitoring device for determining a revised position of a tag, wherein the monitoring device comprises:

a first sensor configured to sense a first set of data;

a second sensor configured to sense a second set of data; and

a processor;

wherein

the processor is configured to;

determine a first parameter associated with the tag based on the first set of data;

determine a second parameter associated with an object based on the second set of data;

determine whether the first parameter corresponds to the second parameter; and

if the first parameter corresponds to the second parameter, determine the revised position of the tag based on the second set of data.

13. The monitoring device of claim 12 further including an alarm.

14. The monitoring device of claim 12 wherein the monitoring device comprises a single unit, comprising a single housing.
