On 2010 August 1, a global solar event was launched involving almost the entire Earth-facing side of the Sun. This event mainly consisted of a C3.2 flare, a polar crown filament eruption and two Earth...
基于CT的水泵叶轮三维重建（Three Dimensional Reconstruction on Impeller of Pumps Based on CT）
水泵 逆向工程 叶轮 模型重建 多层螺旋CT
2010/4/1
针对当前常用的逆向工程方法不能处理水泵零件内部结构的局限性，提出了利用医用多层螺旋CT对水泵叶轮进行透视扫描的方法，并在VC++ 6.0开发平台上，利用一系列数字化图像处理算法对获得的含有叶轮设计与内部构造信息的CT断面图像进行处理，通过预处理、二维图像处理、二维几何处理以及三维图像重建等实现了水泵叶轮的三维表面重建以及表面模型到实体模型的转换，为水泵叶轮的逆向工程提供了一种新的思路。 Aimed...
