| Abstract: | The National Engineering Laboratory (NEL) has considerable experience in using photogrammetry to solve diffcult engineering measurement problems. Applications of close range photogrammetry sometimes have to be carried out using cameras which are not specifically designed for such applications. The calibration techniques used to determine the camera parameters in these cases are discussed and satisfactory solutions demonstrated. Seven examples of the value of photogrammetry in engineering are cited to show that photogrammetry is a valuable non-contacting measurement tool, particularly when dynamic events have to be quantified. |
