ORTHO-IMAGE ACQUISITION METHOD, DESIGN DRAWING CREATION METHOD, DESIGN DRAWING CREATION SYSTEM AND MEMBER FOR SURVEY
To easily acquire an ortho-image in the front view with a little deviation from a direction orthogonal to an object plane when a protruding object protruding from the plane is viewed from the front with respect to the plane.SOLUTION: An ortho-image acquisition method includes: a member for survey installation step of installing a member 10 for survey which has two orthogonal planes 14A1, 14B1 that extend in two different directions orthogonal to an object plane, and which has a dimension portion at least a partial dimension of which is grasped in advance on the object plane; an imaging step of capturing photographs of a protruding object 54 and the member 10 for survey together as subjects from at least two different directions; a three-dimensional model construction step of constructing a three-dimensional model of the protruding object 54 by using the data of the captured photographs; and an ortho-image acquisition step of acquiring an ortho-image in which the constructed three-dimensional model is viewed from the front with respect to the object plane. In ortho-image acquisition step, the direction in which the three-dimensional model is viewed from the font is the direction parallel to both of the two orthogonal planes 14A1, 14B1 of the member 10 for survey.SELECTED DRAWING: Figure 1
【課題】物体平面から突出する突出物を当該平面に正面視する際、当該平面に対して直交する方向からのずれを少なく正面視したオルソ画像を簡易に取得する。【解決手段】物体平面と直交して異なる２方向に広がる２つの直交面１４Ａ１、１４Ｂ１を有するとともに、少なくとも一部の寸法が予め把握されている寸法部位を有する測量用部材１０を前記物体平面に設置する測量用部材設置工程と、突出物５４と測量用部材１０とを被写体として一緒に含む写真を少なくとも異なる２方向から撮影する撮影工程と、撮影した前記写真のデータを用いて、突出物５４の３次元モデルを構築する３次元モデル構築工程と、構築した前記３次元モデルを前記物体平面に対して正面視したオルソ画像を取得するオルソ画像取得工程と、を有し、前記オルソ画像取得工程では、前記３次元モデルを正面視する方向を、測量用部材１０の２つの直交面１４Ａ１、１４Ｂ１の両方と平行な方向にする。【選択図】図１
