Abstract

An object tracking and recognition system are provided and comprise a video device for getting the image information of an object in the detection range of the object tracking and recognition system; and a radio frequency identification (RFID) device for detecting signal strength of a radio frequency (RF) tag of the object; wherein the video device is turned on to get the image information of the object upon the detected signal strength reaching a predetermined signal strength threshold.

Claims

1. An object tracking and recognition system comprising:

a video device for getting image information of an object in detection range of the object tracking and recognition system; and

RFID device for detecting signal strength of a RF tag of the object;

Wherein the video device is adapted to turn on to get the image information of the object upon the detected signal strength reaching a predetermined signal strength threshold.

2. The object tracking and recognition system according to claim 1, further comprising a central processor for updating the predetermined threshold using a relationship model of signal strength in the detection range.

3. The object tracking and recognition system according to claim 1, wherein the relationship model is a linear matrix model of signal strong tin between the regions in the detection range.

4. The object tracking and recognition system according to claim 1, wherein the predetermined threshold corresponds to a distance from the object to the RFID device.

5. The object tracking and recognition system according to claim 1, wherein the predetermined threshold is updated by a single or multiple point estimation method based on the relationship model.

6. The object tracking and recognition system according to claim 1, further comprising a image coordinate or image model for providing coordinate model or image model to the video device and RFID device.

7. The object tracking and recognition system according to claim 1, wherein the object tracking and recognition system is adapted to be arranged on a electronic device to turn on/off the electronic device upon image information detected by the video device and the RFID device.

9. The method used in an object tracking and recognition system according to claim 1.

8. A method used in an object tracking and recognition system comprising:

getting, by a video device, image information of an object in detection range of the object tracking and recognition system; and

detecting, by a RFID device, signal strength of a RF tag of the object;

wherein turning on the video device to get the image information of the object upon the detected signal strength reaching a predetermined signal strength threshold.
