摘要
针对充气膜结构测量难问题,提出采用摄影测量的方法来获取试验数据。在泄气过程中利用摄影测量原理获得膜面标志点的坐标,通过膜面上的各个标志点的位移情况来模拟近似膜面的整体变形情况,从而获得泄气不同时刻膜面整体下降形态,试验研究成果与理论值趋势相同,证明大型结构采用动态摄影测量的可行性。
Inflatable membrane structures are large, the test process is dynamic and can＇ t be realized by general measure methods. So it＇ s more appropriate to obtain the test data through the method of photogrammetry. The coordinates of the measuring points in the membrane surface can be obtained by using photogrammetry principle, and the overall deformation of inflatable membrane structure can be simulated through the displacement of measuring points. Result of the test has the same trend with the theoretical results, so the test method and analysis of data processing in this paper has a certain reference value.
