1. An apparatus for analyzing a motion, the apparatus comprising:
an imaging unit configured to generate a depth image and a stereo image; a ready posture recognition unit configured to transmit a ready posture recognition signal to the imaging unit if a similarity between an actual skeleton model of a user and a standard skeleton model of a ready posture and a similarity between an actual silhouette model of the user and a standard silhouette model of a ready posture are determined to be equal to or greater than a predetermined threshold value with reference to the depth image; a human body model generation unit configured to generate an actual human body model by combining an intensity model, a color model and a texture model of a base model region on the stereo image with an actual base model of the user; a motion tracking unit configured to estimate a position and a rotation value of a rigid body motion of the actual skeleton model that maximizes a similarity between a standard human body model and the actual human body model through an optimization scheme; and a motion synthesis unit configured to generate a motion analysis image by synthesizing a skeleton model corresponding to a rigid body motion with a stereo image or a predetermined virtual character image, wherein the imaging unit, upon receiving the ready posture recognition signal, generates the stereo image.
