| 摘 要： | 采用非接触测量方法—数字立体摄影测量技术获取舰船液舱的数字表面模型(DSM)。摄影测量可在瞬间获取被测目标最大信息,得到大量点的三维坐标。介绍了纹理点投影,立体相机的组成,旋转(水平360°竖直90°)摄影的方式以及纹理点匹配得到点的三维坐标形成DSM的全过程。实验数据显示某船舱的DSM,论证了本文方法的可行性。

| Abstract: | This paper got the DSM of vessel surface by digital stereo photogrammetry. Photogrammetry acquired much information of objects at moment,and three dimensions (3D)coordination of a large number of points. The paper introduced the project of texture dots, structure of stereo camera,rotate shoot whole inner vessel,matching texture dots,getting 3D coordination,making DSM. Experiment data showed a vessel DSM,proving feasibility of the method. |
