Photogrammetry is the art, science, and technology used in the interpretation of coordinate data about physical objects by the measurement and analysis of photographic images. The Electric Boat Division of General Dynamics utilizes photogrammetry primarily, in measuring the as-built circularity out-of-roundness of the TRIDENT Class pressure hull cylinders. Various other mechanical methods had been used in the past for measuring hull circularities but the unique features and capabilities of photogrammetry proved itself well to meet demanding shipyard needs. pressure hull cylinders, The large awkward shape of submarine in combination with the flexibility and ease of the photogrammetric technique, makes photogrammetry a productive tool for Electric Boats shipbuilding applications.
