To solve the problem, in which in exhibit-purpose 3D shapes of museums or art museums, a need for creating a 3D shape having an upper face, lateral face and bottom face synthesized has been present, but in 3D shape creation software [Agisoft Photoscan], for example, if the subject is photographed while changing a relative position between the subject and a peripheral landscape such as photographing the upper face and the lateral face of the subject, and next, photographing the bottom face with the subject upside down, and the like, the Agisoft Photoscan is not consistent with an image creation algorithm identifying the 3D shape from a characteristic point of the shape and a color of each characteristic point, which in turn the 3D shape cannot be created.SOLUTION: By putting a subject on a monochrome rotor type subject pedestal, and blocking a landscape rearward using a monochrome rear screen blocking rearward the subject, even when photographing the subject as changing a relative position between the subject and a peripheral scape, a 3D shape of an entire face of an upper face, lateral face and bottom face can be created.SELECTED DRAWING: Figure 11 【課題】 博物館や美術館の展示物用３Ｄ形状において、上面、側面、底面が合成された３Ｄ形状を生成したいニーズがある。しかしながら、３Ｄ形状生成ソフトウェア「アギソフトフォトスキャン」は、例えば、被写体の上面と側面を撮影し、次に、被写体を逆さにして底面を撮影するなど、被写体と周辺風景の相対位置を変えて撮影すると、形状の特徴点と各特徴点の色から３Ｄ形状を識別する画像生成アルゴリズムに合致しないため、３Ｄ形状を生成できない。【解決手段】 被写体を単一色の回転体型の被写体台座に乗せ、被写体の後方を遮蔽する単一色のバックスクリーンを用いて後方の風景を遮断することにより、被写体と周辺風景の相対位置を変えて撮影しても、被写体の上面、側面、底面の全面の３Ｄ形状を生成することができる。【選択図】図１１
