3-D Reconstruction of High Energy X-Ray Film Images of the SRM
-
摘要: 固体火箭发动机是导弹武器系统的主要动力装置, 需要定期进行无损检测。常规的检测方法是对X射线照相得到的二维胶片进行评判, 然而利用二维图像来反映三维空间结构, 在直观显示上存在很大的缺陷性。介绍了利用二维胶片图像还原发动机的空间三维结构的基本重建原理和六大体系结构, 即数字图像的获取、各项参数的标定、图像的预处理和特征提取、图像的立体匹配以及图像信息三维重建。Abstract: The SRM is needed to be tested, which is the mostly power equipment of the missile weapon system. Judging 2-D X-ray films of the SRM is the traditional method. It has many limitations on intuitive showing just using two dimension films because the SRM is 3-D object. 3-D reconstruction theory of the SRM by the two film images is studied in this paper. There have six parts: obtaining of digital images, demarcating of different parameter, pre-processing and feature extraction of digital images, feature matching, 3-D reconstruction of image’s information.
