To provide a measuring apparatus, a measuring program, and a measuring method that are inexpensive and highly convenient for measuring the dimensions of an object to be measured.SOLUTION: The present invention relates to a measuring apparatus including imaging means and display means. The measuring apparatus generates a rectangular parallelepiped shaped virtual object for measuring, which is associated with a coordinate system of a real space in which an object to be measured is placed, synthesizes an image of the virtual object for measuring with a picked-up image to display the synthesized image on a screen of the display means, recognizes a surface of the object to be measured with which an optical axis of the imaging means is brought into contact as a target surface, determines any position of the target surface as a target point, determines a surface in a direction closest to the target surface on the virtual object for measuring as an object surface, adjusts dimensions of the object surface of the virtual object for measuring in a normal direction so that the object surface moves in a direction approaching the target point, and acquires and outputs a measurement parameter concerning a shape of the current virtual object for measuring.SELECTED DRAWING: Figure 1 【課題】 低コストで且つ利便性の高い被測定物の寸法を測定する。【解決手段】 本発明は、撮像手段と、表示手段とを備える測定装置に関する。そして、本発明の測定装置は、被測定物が配置された現実空間の座標系と紐づけられた直方体形状の測定用仮想オブジェクトを生成し撮像画像に測定用仮想オブジェクトの画像を合成して表示手段の画面に表示させ、被測定物で撮像手段の光軸が当接する面を目標面として認識し目標面のいずれかの位置を目標点として決定し測定用仮想オブジェクト上で目標面と最も向きの近い面を対象面として決定し対象面が目標点に近づく方向に移動するように測定用仮想オブジェクトの対象面の法線方向の寸法を調整し、現在の測定用仮想オブジェクトの形状に関する測定パラメータを取得して出力することを特徴とする。【選択図】 図１
