Abstract
A modelling apparatus including a three-dimensional information input unit for measuring and inputting three-dimensional information concerning objects in a space. An environmental model processing unit constructs an environmental model for each object in the space by comparing prestored object data to the three-dimensional information. A picture composing unit composes an artificial picture from a specific viewpoint within the space according to the environmental model constructed by the environmental model processing unit. An analyzing unit validates the environmental model by comparing the artificial picture composed by the picture composing unit with the three-dimensional information from the specific viewpoint. An observation control unit controls the measurement and input operation of the three-dimensional information input unit according to the result of validation by the analyzing unit.
