12. The method of claim 11 , wherein the spatial information or the object information includes: an actual measurement information layer including actual measurement information; a photometric information layer including photometric features; a geometric information layer including information about sub-parts obtained by dividing an object or a space by a geometric structure; a structural information layer including information obtained by dividing constituent elements of a space or an object and symbolizing and layering information about the divided constituent elements; a topological information layer including information for representing locations of objects or obstacles in a space; a generic information layer including information about generic models of a space, an object, or constituent elements of the space or the object; a reasoning information layer including reasoning information for reasoning about a space, an object or states of the space and the object from object or spatial information of lower information layers.
12. The method of claim 11 , wherein the spatial information or the object information includes: an actual measurement information layer including actual measurement information; a photometric information layer including photometric features; a geometric information layer including information about sub-parts obtained by dividing an object or a space by a geometric structure; a structural information layer including information obtained by dividing constituent elements of a space or an object and symbolizing and layering information about the divided constituent elements; a topological information layer including information for representing locations of objects or obstacles in a space; a generic information layer including information about generic models of a space, an object, or constituent elements of the space or the object; a reasoning information layer including reasoning information for reasoning about a space, an object or states of the space and the object from object or spatial information of lower information layers. 18. The method of claim 12 , wherein in the step g), if requested information includes information about a base map of the actual measurement information layer for a space and object/obstacle location information of the topological information layer, a united map is composed by combining the information about the base map and the object/obstacle location information.
