METHOD OF GENERATING A 3D IMAGE FROM A TWO-DIMENSIONAL IMAGE TO GENERATE THE 3D IMAGE IMMEDIATELY AT A POINT OF VIEW OF A CERTAIN CAMERA THROUGH REAL-TIME INTERACTION WITH A USER

PURPOSE: A method of generating a 3D(three-Dimensional) image from a two-dimensional image is provided to generate the 3D image immediately at a point of view of a certain camera through real-time interaction with a user by allowing a user to adjust a parameter. CONSTITUTION: A 2D image is inputted(S10). A background and a foreground are separated from the inputted 2D image(S20). The separated background is modeled in a predetermined 3D area on a basis of a vanishing point of the background(S30). The foreground is modeled so that the separated foreground is located in the modeled background(S40). The length of each area of the modeled background is made as a parameter(S50). The parameter is adjusted and thereby the length of each area thereof may be adjusted(S80). A camera is moved to a position according to the length thereof and then a 3D image at the position is generated(S90).
