User Friendly 3-D Interior Image Generation System Using Photograph Image

Abstract

A graphic model generation system for house interiors has been developed. The system generates an interior image which fits a user's idea. The system includes an interior picture database which can be accessed interactively using key words to select a desired picture. The system generates a graphic model by mapping part images included in the selected picture on a specified room structure. The dimensions and view points of the picture in the database and the specified room are different. Therefore, the graphic model is three-dimensional. To construct a three-dimensional parts image database, a picture image is recognized by a monocular vision algorithm, and normalized images, sizes, and locations in a room space of the picture are calculated. Using these data, part images can be mapped on a specified room structure. The system was utilized in a home electronics presentation system to generate a photorealistic environment model. This environment model helps in appearence design evaluation and setting of product specifications to fill customer requirements.
