【摘要】 大型工业CT是检测大型火箭和导弹的重要手段,由于被检物和检测系统过于庞大和笨重,因而采用螺旋扫描方式。在需要了解被检部位上下关系时,需要对获得的断层图像进行多平面重组,并应用交互可视化技术,在计算机上获得空间图形或任意平面的图像。本文讨论了各种多平面重组的方法及其特性,描述了如何在Windows环境下用OpenGL实现三维交互可视化,并给出了一个简单的三维交互可视化程序和结果。更多还原

【Abstract】 A Large Industrial CT is the important method of examining Urge rockets and missiles. The method of spiral scan is used because the objects and the detection system are excessively huge and heavy. When the up-down structural relation of a certain part is examined, the method of multiplanar reformatting and the interactive visualization, must be applied. This article discusses the various methods of multiplanar reformatting mainly , describes how to achieve the interactive visualization with OpenGL under the Windows environment, and presents the method of achievement and result of a simple experimental program of 3D interactive visualization.更多还原
