PROBLEM TO BE SOLVED: To identify the location and orientation of each mounting receptacle (e.g., mounting point, mounting hole, etc.) for an aircraft fairing, utilizing photogrammetric techniques.SOLUTION: Systems and methods are provided for identifying a location to perform work (e.g., drilling). A method includes acquiring images of a hole in a first object from multiple lighting angles, processing the images to identify shadows cast by a wall of the hole at each of the lighting angles, and analyzing the shadows to determine an orientation of a central axis of the hole in a coordinate system of the first object. The method also includes, at a second object, selecting a location to drill that will be aligned with the central axis of the hole of the first object, and drilling the second object at the location.SELECTED DRAWING: Figure 12

    【課題】写真測量技術を利用して航空機フェアリング用の各取付け受け部(例えば、取付け点や取付け孔など)の箇所および向きを識別すること。【解決手段】作業(例えば、穴あけ)を行うべき箇所を識別するためのシステムおよび方法が提供される。複数の照明角度から第1の物体の孔の画像を取得するステップと、画像を処理して照明角度のそれぞれで孔の壁によって作られた影を識別するステップと、影を分析して第1の物体の座標系で孔の中心軸線の向きを決定するステップと、を含む。この方法はまた、第2の物体において、第1の物体の孔の中心軸線と一致する穴をあけるべき箇所を選定するステップと、その箇所で第2の物体に穴をあけるステップと、を含む。【選択図】図12
