A VR motion simulator allowing a user to experience a vertical motion in VR environment by analyzing a pressure distribution of a sole of the user and estimating a posture of the user, and a method of implementing a vertical motion action of a user in VR. The simulator includes a pressure distribution image generating module generating a pressure distribution image of a sole of a user at a time of a vertical motion of the user; a sole position tracking module analyzing the pressure distribution image to detect the sole of the user, and track a position of the sole on the basis of movement of the detected sole to output sole position tracking information; and a posture estimating module estimating a posture of the user on the basis of the sole position tracking information to output posture estimation information.

Vertical motion simulator and method of implementing virtual reality of vertical motion using the same

Provided are an apparatus and method for detecting a plurality of arms and hands by using a three-dimensional (3D) image. The apparatus includes an image input unit configured to acquire a 3D image of an object, an arm detecting unit configured to detect one or more component-unit candidate regions of the object in the 3D image, and detect one or more arm regions by using arm detection feature information, extracted from each of the candidate regions, and a pattern recognition algorithm, and a hand detecting unit configured to calculate a position of a hand and a position of a wrist in each of the arm regions detected by the arm detecting unit, and detect a hand region by using the position of the hand and the position of the wrist.
