Web环境下人体数据集三维可视化初步研究

目的使用可视化工具包(theVisualizationToolKit,VTK)的重建算法对中国可视化人(Chinesevisiblehu-man,CVH)数据集进行重建,结合虚拟现实建模语言(virtualrealitymodelinglanguage,VRML),互联网环境下实现远程访问并对重建结果进行交互操作。方法应用数字化可视人体数据获取技术,对双侧肱骨图片进行三维重建,生成基于网络的立体结构。结果重建出双侧肱骨的三维立体图像,在网络浏览器窗口能任意角度和比例大小对它们进行观察,清楚显示了其空间位置关系。结论本研究以VTK和VRML为基础,实现CVH数据集三维可视化重建,为深入研究和实现更多解剖结构可视化以及科学计算提供支持,也为解剖远程网络教学提供了范例。

Pilot study on 3D visualization of Human Dataset under web condition

Objective To reconstruct the Chinese visible human (CVH) dataset with the reconstruction algorithm, the Visualization Toolkit (VTK), and to realize long-distance accessing and alternating operation associated with virtual reality modeling language (VRML) under web condition. Methods 3D structure of the humerus was reconstructed and put out in web condition by applying the methed of capturing data of digitalized visible human. Results The 3D structure of the humerus was successfully reconstructed. These 3D images displayed the anatomical relationships of the structures of the humerus in explore windows with any angle and scale. All reconstructed structures were represented conveniently. Conclusion Based on VTK and VRML, 3D reconstruction of the humerus is realized, which will provide the support and reference for further research on the others structure's visualization of human body, and also for Visualization in Scientific Computing and long-distance teaching in anatomy.
