Abstract
In this paper, we propose the method of three dimensional recovery from a photograph. In general, two photographs are used in the case of three dimensional recovery. Three dimensional recovery cannot be solved from a photograph. In the other hand, human percept the three dimension from a photograph. This is reason why the knowledge exists from experiences. In this paper, we generate three dimensional space from a photograph by showing knowledge. We use the vertical relations between quadrangles and vertical relations between vertices of quadrangles as the knowledge. We show the effectiveness of this method by recovering three dimensional space from a photograph.
