GESTURE RECOGNITION APPARATUS, ROBOT SYSTEM INCLUDING THE SAME AND GESTURE RECOGNITION METHOD USING THE SAME
First Claim
1. A gesture recognition apparatus, comprising:
- a human detection unit detecting a face region of a user from an input image;
a gesture region setting unit setting a gesture region, in which a gesture of the user'"'"'s arm occurs, with respect to the detected face region;
an arm detection unit detecting an arm region of the user in the gesture region; and
a gesture determination unit analyzing a position, moving directionality and shape information of the arm region in the gesture region to determine a target gesture of the user.

Abstract
Provided is a gesture recognition apparatus. The gesture recognition apparatus includes a human detection unit, a gesture region setting region, an arm detection unit and a gesture determination unit. The human detection unit detects a face region of a user from an input image. The gesture region setting unit sets a gesture region, in which a gesture of the user'"'"'s arm occurs, with respect to the detected face region. The arm detection unit detects an arm region of the user in the gesture region. The gesture determination unit analyzes a position, moving directionality and shape information of the arm region in the gesture region to determine a target gesture of the user. Such a gesture recognition apparatus may be used as a useful means for a human-robot interaction in a long distance where a robot has difficulty in recognizing a user'"'"'s voice.

17. A robot system which includes a moving means and implements a human-robot interaction, the robot system comprising:
-
a single camera acquiring a low-resolution input image which comprises a user disposed in a certain long distance; and a gesture recognition apparatus recognizing a target gesture of the user, wherein the gesture recognition apparatus comprises; a human detection unit detecting a face region of the user from an input image; a gesture region setting unit setting a gesture region, in which a gesture of the user'"'"'s arm occurs, with respect to the detected face region; a background image acquisition unit acquiring a background image for stably detecting an arm region of the user in the set gesture region; an arm detection unit detecting an arm region of the user in the gesture region by using the acquired background image; and a gesture determination unit analyzing a position, moving directionality and shape information of the arm region in the gesture region to determine a target gesture of the user. - View Dependent Claims (18)

19. A gesture recognition method using a robot system which includes a moving means and in which a human-robot interaction technology is implemented, the gesture recognition method comprising:
-
detecting a face region of a user from an input image which is sequentially inputted; calculating a size of a gesture region, in which a gesture of the user'"'"'s arm occurs, at a certain rate on the basis of a position and size of the detected face region; acquiring a background subtraction image which comprises an arm region of the user in the calculated gesture region; detecting the arm region of the user in the gesture region by using the acquired background subtraction image; and analyzing a position, moving directionality and shape information of the arm region in the gesture region to determine a target gesture of the user which comprises a waving gesture, a calling gesture, a raising gesture and a stopping gesture. - View Dependent Claims (20)
