Method for reconstructing three-dimensional information of object and apparatus for the same

An apparatus for reconstructing 3D information of an object, the apparatus comprising:

• at least one of cameras taking images for reconstructing 3D information;
• a background information reconstructor reconstructing 3D information of a background space for three-dimensionally reconstructing an object, using at least one of images of the background space;
• a background/object separator separating the object from the background space on the basis of at least one of images of the object in the background space, and obtaining a depth image of the object separated from the background space;
• and
• a 3D information reconstructor generating 3D information of the object based on images taken by the cameras in consideration of positional relationships between the depth image of the object and the cameras.
