ARITHMETIC DEVICE, ARITHMETIC METHOD, AND PROGRAM
To make it possible to acquire three-dimensional information obtained from a viewpoint on a heavy machine.SOLUTION: An arithmetic device obtains positioning data by positioning while tracking the position of a reflecting prism 102 of a heavy machine 100 equipped with a camera 101 and the reflecting prism 102, by a total station 200 with an external targeting element known in a specific coordinate system, acquires image data of a plurality of captured images in which overlapping ranges are captured by the camera 101 from a plurality of different positions, calculates the relative positional relationship between a plurality of feature points p1, p2, and p3 extracted from the plurality of captured images and the plurality of different positions of the camera 101, calculates the trajectory of the movement of the camera 101 with respect to the plurality of feature points p1, p2, and p3 based on a change in the relative positional relationship, and finds the positions of the plurality of feature points p1, p2, and p3 in the specific coordinate system based on the comparison of the calculated trajectory of the movement of the camera 101 and the positioning data.SELECTED DRAWING: Figure 2
【課題】重機上の視点から得た三次元情報の取得を可能とする。【解決手段】カメラ１０１と反射プリズム１０２を搭載した重機１００の反射プリズム１０２の位置を特定の座標系上での外部標定要素が既知のトータルステーション２００により追尾しつつ測位して測位データを得、カメラ１０１により異なる複数の位置から重複する範囲が撮影された複数の撮影画像の画像データを取得し、前記複数の撮影画像から抽出された複数の特徴点ｐ１，ｐ２，ｐ３とカメラ１０１の前記異なる複数の位置との相対的な位置の関係を算出し、該相対的な位置の関係の変化に基づく前記複数の特徴点ｐ１，ｐ２，ｐ３に対するカメラ１０１の移動の軌跡の算出を行い、該算出されたカメラ１０１の移動の軌跡と前記測位データの比較に基づく前記複数の特徴点ｐ１，ｐ２，ｐ３の前記特定の座標系における位置を求める。【選択図】図２
