三维摄影测量技术在水轮机叶片制造中的应用

摘要

It can effectively overcome the disadvantages of contact measurement such as low efficiency and narrow measuring range to use 3D photogrammetric technology for measuring casting of blades is carried on. In this paper, the measuring principle of 3D photogrammetric technology is described in detail, 3D photogrammetric experiment for casting of some turbine blades, and then the results are analyzed.%　　利用三维摄影测量技术对叶片铸件进行检测，有效避免了接触式测量方法效率低和测量范围小的缺点。本文重点介绍了三维摄影测量技术的测量原理，并针对某水电站叶片铸件进行了三维摄影测量实验，最后对实验结果进行了分析。
