摘要： PURPOSE: A plane-based three dimensional space expressing method and an apparatus thereof are provided to express a real world in a simple mode. CONSTITUTION: An extracting unit performs a space division of a color image or depth image (202) which corresponds to a real world (201). The extracting unit extracts one or more areas. A generating unit generates each planar structure (203) of the extracted areas. An expressing unit expresses the generated planar structure in a planar model (204). The expressing unit expresses the planar structure in a plane equation which is a parameter model.
