Abstract

Described herein is a system and method of activating vehicle electromechanical systems based on image recognition and radio frequency systems. The system includes radio frequency (RF) antennas for receiving wireless communication signals from a transponder. A RF controller verifies that the transponder is associated with the vehicle. Upon detection and verification of the transponder, a camera system captures images and an image processing engine determines if the images contain valid gestures associated with commands for the electromechanical systems. A controller triggers the electromechanical systems to perform the command if the gesture is valid. For example, the command may be an activation or deactivation command.

Claims (50)

1. A system for activating an electromechanical system in a vehicle, comprising:

at least one radio frequency (RF) antenna that receives wireless communication signals from a transponder;

a RF controller communicatively coupled to the at least one RF antenna;

at least one camera attached to the vehicle that captures a gesture;

an image processing engine communicatively coupled to the at least one camera; and

a controller communicatively coupled to the image processing engine;

wherein the RF controller:

verifies that transponder is associated with the vehicle, and

changes a power state of the imaging processing engine from a low power consumption state to a high power consumption state on a condition that the transponder is verified to be associated with the vehicle;

wherein when in the high power state the image processing engine:

determines that a captured gesture is a valid command; and

wherein the controller:

triggers a predetermined function associated with the electromechanical system on a condition that the captured gesture is a valid command, wherein the predetermined function activates the electromechanical system to open a vehicle entry point responsive to the captured gesture.

2. The system of claim 1 , wherein the image processing engine is integrated with one of the at least one camera or the controller.

3. The system of claim 1 , wherein the image processing engine, the RF controller and the controller are integrated.

4. The system of claim 1 , wherein the RF controller is integrated with the controller.

5. The system of claim 1 , wherein the command is a predetermined gesture sequence or pattern associated with the electromechanical system or the predetermined function associated with the electromechanical system.

6. The system of claim 1 , wherein the at least one camera includes a camera internal to the vehicle configured to capture an internal gesture; and wherein the image processing engine determines that the captured internal gesture is a valid command.

7. A method for activating an electromechanical system in a vehicle, comprising:

determining radio frequency (RF) detection of a transponder associated with the vehicle using a RF antenna;

verifying that the transponder is associated with the vehicle using a RF controller communicatively coupled to the RF antenna;

changing, via the RF controller, a power state of at least one image sensor from a low power consumption state to a high power consumption state on a condition that the transponder is verified to be associated with the vehicle;

energizing the at least one image sensor;

capturing by the at least one image sensor a gesture on a condition that the transponder has been detected and the at least one image sensor is energized;

determining by a gesture recognition system that the captured gesture is a valid command, wherein the gesture recognition system is communicatively coupled to the at least image sensor; and

triggering, by a controller communicatively coupled to the gesture recognition system, the electromechanical system on a condition that the captured gesture is a valid command, wherein the electromechanical system opens a vehicle entry point responsive to the captured gesture.

8. The method of claim 7 , wherein wireless communications signals corresponding to the transponder are received by RF antennas.

9. The method of claim 7 , wherein image sensors are polled to capture gestures.

10. The method of claim 9 , wherein an image sensor located nearest to an RF antenna detecting the transponder is polled first.

11. The method of claim 7 , wherein the command is a predetermined gesture sequence or pattern associated with the electromechanical system.

12. The method of claim 7 , wherein the captured gestures are captured by the at least one image sensor within a predetermined time.

13. The method of claim 7 , wherein the captured gestures are captured by the at least one image sensor and analyzed by the gesture recognition system within a predetermined time.

14. A vehicle including electromechanical systems, comprising:

a radio frequency (RF) system;

an image recognition system communicatively coupled to the RF system; and

a controller communicatively coupled to the image recognition system;

wherein the RF system:

detects wireless communication signals from a transponder associated with the vehicle,

verifies that transponder is associated with the vehicle,

changes a power state of the image recognition system from a low power consumption state to a high power consumption state on a condition that the transponder is verified to be associated with the vehicle, and

energizes the image recognition system when the transponder is detected;

wherein the energized image recognition system:

captures images on a condition that the transponder has been detected;

determines that the captured images contain a gesture that is a valid command; and

the controller triggers the electromechanical system on a condition that the captured gesture is a valid command, wherein the electromechanical system opens a vehicle entry point responsive to the captured gesture.

15. The vehicle of claim 14 , wherein the image processing system is integrated with the image capture system or the controller.

16. The vehicle of claim 14 , wherein the image processing system, a part of the RF system and the controller are integrated.

17. The vehicle of claim 14 , wherein part of the RF system is integrated with the controller.

18. The vehicle of claim 14 , wherein the command is a predetermined gesture sequence or pattern associated with the electromechanical system.

19. The vehicle of claim 14 , wherein the image recognition system includes a recognition system internal to the vehicle independent of the detection of the transponder.
