A 3D motion recognition apparatus and a method thereof are disclosed. The 3D motion recognition apparatus can extract and track an object which is a moving region by using an image inputted through a 3D camera. The 3D motion recognition apparatus can generate a 3D motion history image by using the depth information of the image and calculate the motion of a joint, with regard to the tracked object, and the 3D motion recognition apparatus can determines the motion of the object by using the motion of the joint and the 3D volume motion history image. Accordingly, the present invention can recognize the motion at various angles regardless of the viewing point of the camera.
