description PROBLEM TO BE SOLVED: To superpose additional information on a photographic image of a building, and make it possible to share the information among plural photographic images.SOLUTION: A photographic image of an object building obtained while an investigation vehicle is run downtown is displayed on a screen. A 3D model is separately prepared for the object building. When an operator finds parts of new and previous images showing a time-sequential change, the operator defines a point or area in an image, and specifies a correction point of the 3D model as additional information. The point in the image is transformed into three-dimensional coordinates on the basis of a point-of-view position and line-of-sight direction, which are attained during photographing, under a constraining condition that the point in the image should be a point on a wall of a building, and stored in a database together with a specified content. Since additional information with three-dimensional coordinates is produced, once the additional information is projected in perspective, the additional information can be superposed on a photographic image which is produced by photographing the object building in a different direction. Thus, information can be shared among plural photographic images. 【課題】 建物の実写画像に対して、付加情報を重畳して表示するとともに、複数の実写画像間で情報の共有を可能とする。【解決手段】 調査車両によって街中を走行して得られた対象建物の実写画像を画面に表示する。対象建物には、別途、3Dモデルが用意されている。オペレータは、新旧画像において経年変化が生じている部分を見いだすと、画像上で点または領域を指定し、3Dモデルの修正点を付加情報として指示する。画像上の点は、建物の壁面上の点であるという拘束条件の下、画像撮影時の視点位置、視線方向に基づいて3次元座標に変換され、指示内容とともにデータベースに格納される。このように3次元座標を伴う付加情報を生成することにより、これを透視投影すれば、対象建物を異なる方向から撮影した実写画像上にも付加情報を重畳表示することができ、複数の実写画像間で情報の共有が可能となる。【選択図】 図4
