Abstract

A misrecognition reducing motion recognition apparatus and method are provided. A photographing unit of the apparatus photographs an image within a vehicle and a controller detects a thermal change within a set region. The controller operates a corresponding device within the vehicle by recognizing a gesture motion from the photographed image in response to determining that the gesture motion exists by the detection of the thermal change.

Claims

1. A motion recognition apparatus, comprising:

a memory configured to store program instructions; and

a processor configured to execute the program instructions, the program instructions when executed configured to;

photograph an image within a vehicle;

detect a thermal change within a set region; and

operate a corresponding device within the vehicle by recognizing a gesture motion from the photographed image in response to determining that the gesture motion exists by the detection of the thermal change.

2. The motion recognition apparatus of claim 1, wherein the program instructions when executed are further configured to:

determine existence and nonexistence of the motion through existence and nonexistence of the thermal change;

recognize the gesture motion from the photographed image in response to determining existences of the motion; and

operate the device within the vehicle based on the recognized gesture motion.

3. The motion recognition apparatus of claim 2, wherein the program instructions when executed are further configured to:

extract a detailed image from the photographed image;

store a plurality of elements of gesture information in a gesture database (DB) to operate the device within the vehicle; and

recognize a gesture motion that corresponds to the detailed image using the gesture information stored in the gesture DB.

4. The motion recognition apparatus of claim 1, wherein a pyro-electric sensor is used to detect an external thermal change and is configured to output a signal that corresponds to the detected thermal change.

5. The motion recognition apparatus of claim 4, wherein the pyro-electric sensor sets a region in which the thermal change is detected by adjusting a view angle of a lens.

6. A method of recognizing a motion by a motion recognition apparatus installed within a vehicle, the method comprising:

determining, by a controller, existence and nonexistence of the motion by detection of a thermal change within a set region;

photographing, by the controller, an image in response to determining that the motion exists;

recognizing, by the controller, a gesture motion from the photographed image; and

operating, by the controller, a device within the vehicle based on the recognized gesture motion.

7. The method of claim 6, wherein a pyro-electric sensor is used to determine the existence and nonexistence of the motion.

8. The method of claim 7, wherein in the determination of the existence and nonexistence of the motion, the region in which the thermal change is detected is set by adjusting a view angle of the lens of the pyro-electric sensor.

9. A motion recognition apparatus, comprising:

a photographing unit configured to photograph an image within a vehicle;

a memory configured to store program instructions; and

a processor configured to execute the program instructions, the program instructions when executed configured to;

detect a thermal change within a set region;

store the photographed image;

operate a corresponding device within the vehicle by recognizing a gesture motion from the stored image in response to determining that a gesture motion exists by the detection of the thermal change.

10. The motion recognition apparatus of claim 9, wherein the program instructions when executed are further configured to:

determine existence and nonexistence of the motion through detected existence and nonexistence of the thermal change;

recognize the gesture motion from the stored image in response to determining existence of the motion; and

operate the device within the vehicle based on the recognized gesture motion.

11. The motion recognition apparatus of claim 10, wherein the program instructions when executed are further configured to recognize the gesture motion using the image photographed during a predetermined time section, in which the motion existence is determined, and stored among the stored images.

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

program instructions that determine existence and nonexistence of the motion by detection of a thermal change within a set region;

program instructions that control an imaging device to photograph an image in response to determining that the motion exists;

program instructions that recognize a gesture motion from the photographed image; and

program instructions that operate a device within the vehicle based on the recognized gesture motion.

13. The non-transitory computer readable medium of claim 12, wherein a pyro-electric sensor is used to determine the existence and nonexistence of the motion.

14. The non-transitory computer readable medium of claim 13, wherein in the determination of the existence and nonexistence of the motion, the region in which the thermal change is detected is set by adjusting a view angle of the lens of the pyro-electric sensor.
