A system for wearing imaginary 3d footwear and an operation method of the same

3D virtual shoe is disclosed worn system and its operating method. The three-dimensional virtual shoe wear system calibration unit which are spaced apart from each other to perform a 3D depth corrected using the two cameras, two of the images at the same time on the camera for collecting image information on the leg portion of the person from a different angle, generating a boundary line (silhouette) in the foot region of the leg portion, and a feature point (specific point) to acquire, and the posture of the virtual shoe according to the operation control unit, the displacement of the three-dimensional position value to calculate the 3D position values It converts the estimation unit and the coordinates of the virtual shoe for estimating the actual coordinates comprises a rendering unit for rendering the foot area. Thus, the two, the camera having a so to obtain a three-dimensional data becomes less area that is covered by the relative, and also, since by having a camera, which is generally commercially available can configure the system, as a relatively small cost-effective there are advantages to build the system.
