PROBLEM TO BE SOLVED: To measure an accurate size of a three-dimensional shape.SOLUTION: A measuring gauze 10 includes a gauze cloth, and a marker part constituted by arranging a plurality of feature points 13 having each color optically distinguishable from a ground color of the gauze cloth at a prescribed interval in the longitudinal direction and in the lateral direction. The measuring gauze 10 is allowed to adhere to a measurement object, the measuring gauze 10 is photographed, and a three-dimensional position of each feature point 13 is recognized, to thereby measure the three-dimensional shape of the measurement object.SELECTED DRAWING: Figure 1【課題】３次元形状の正確なサイズを計測することが可能になる。【解決手段】計測用ガーゼ１０は、ガーゼ生地と、ガーゼ生地の地の色と視覚上区別可能な色の特徴点１３を所定の間隔で縦方向及び横方向に複数配置して構成したマーカー部と、を備える。計測用ガーゼ１０を計測対象に密着させ、計測用ガーゼ１０を撮影し、特徴点１３の３次元位置を認識することによって、計測対象の３次元形状を計測することができる。【選択図】図１
