Abstract

A vehicle having a gesture detection system and a gesture detection method of a vehicle are provided. The system includes an ignition key that has a first light source disposed on a first side of the ignition key and an imaging device that is disposed at one side of a vehicle body to detect the image of the first light source. An image processor is configured to processes the image detected by the imaging device to detect a movement trace of the first light source and a controller configured to execute a function based on the shape or characteristics of the movement trace detected by the image processor. Accordingly, the function of a vehicle is controlled by operating an ignition key through a first light source or source second light source disposed on the ignition key.

Claims

1. A vehicle having a gesture detection system, comprising:

an ignition key having a first light source on a first side of the ignition key;

an imaging device disposed at one side of a vehicle body to detect the image of the first light source;

an image processor configured to process the image detected by the imaging device to detect a movement trace of the first light source; and

a controller configured to execute a vehicle function based on the shape or characteristics of the movement trace detected by the image processor.

2. The vehicle having a gesture detection system of claim 1, further comprising:

a second light source disposed on a second side of the ignition key, wherein the controller is configured to execute a vehicle function based on the shape or characteristics of the movement trace of the first and second light sources.

3. The vehicle having a gesture detection system of claim 2, wherein at least one of the first and second light sources is a light emitting diode (LED).

4. The vehicle having a gesture detection system of claim 1, further comprising:

a photo sensor configured to recognize a frequency transmitted from the first light source and operate the imaging device based on the recognized frequency.

5. The vehicle having a gesture detection system of claim 1, wherein the controller is further configured to execute the vehicle function selected from a group consisting of:

a window, an air-conditioner, a parking brake, a vehicle light, and a door.

6. The vehicle having a gesture detection system of claim 1, wherein the imaging device is configured to detect a lane of a road or a surrounding object.

7. The vehicle having a gesture detection system of claim 1, wherein the ignition key is portable.

8. A gesture detection method of vehicle, comprising:

detecting, by a controller, an image based on a light signal generated from a first light source disposed on a first side of an ignition key;

processing, by the controller, the detected image to extract image data;

calculating, by the controller, trace movement of the first light source from the extracted image data; and

operating, by the controller, a plurality of vehicle functions based on the shape or characteristics of the trace movement of the first light source,

9. The method of claim 8, further comprising:

operating, by the controller, the plurality of vehicle functions based on the shape or characteristics of the movement trace of the first light source and a second light source disposed on a second disposed of the ignition key.

10. The method of claim 9, wherein at least one of the first and second light sources is a light emitting diode (LED).

11. The method of claim 8, further comprising:

recognizing, by the controller, a frequency transmitted from the first light source based on information from a photo sensor; and

operating, by the controller, an imaging device based on the recognized frequency.

12. The method of claim 8, wherein the plurality of vehicle functions are selected from a group consisting of:

a window, an air-conditioner, a parking brake, a vehicle light, and a door.

13. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that control an imaging device to detect an image based on a light signal generated from a first light source disposed on a first side of an ignition key;

program instructions that process the detected image to extract image data;

program instructions that calculate trace movement of the first light source from the extracted image data; and

program instructions that operate a plurality of vehicle functions based on the shape or characteristics of the trace movement of the first light source.

14. The non-transitory computer readable medium of claim 13, further comprising:

program instructions that operate the plurality of vehicle functions based on the shape or characteristics of the movement trace of the first light source and a second light source disposed on a second disposed of the ignition key.

15. The non-transitory computer readable medium of claim 14, wherein at least one of the first and second light sources is a light emitting diode (LED).

16. The non-transitory computer readable medium of claim 13, further comprising:

program instructions that recognize a frequency transmitted from the first light source based on information from a photo sensor; and

program instructions that operate the imaging device based on the recognized frequency.
