FURNITURE SIMULATION METHOD, DEVICE, PROGRAM, RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a furniture simulation method which can superimpose a furniture CG image without sense of incongruity on an indoor real image by proofreading an internal parameter of a camera after photographing furniture.

SOLUTION: The furniture simulation method is performed by a procedure including the steps in which: (1) an operator photographs the interior of a room with a standard marker placed therein by a digital camera; (2) the operator photographs a proofreading pattern by the digital camera with the same focal distance as that when the interior of the room is photographed set therein; (1) a furniture simulation device derives a camera internal parameter from a proofreading pattern photographed image; (2) the furniture simulation device applies the camera internal parameter to a standard marker image of the interior photographed image to derive three-dimensional orthographic projection conversion relation expression; and (3) the furniture simulation device applies the three-dimensional orthographic projection conversion relation expression to furniture model data to generate a furniture CG image data and superimposing the furniture CG image data on the interior photographed image data to display the superimposed image data.
