摘要
目的对三维人体虚拟内窥系统进行初步的实验研究。方法建立了虚拟摄像机几何模型和定位方法，根据人体的三维影像数据，以不同分辨率对虚拟人体进行不同角度的观察。并对虚拟内窥镜的观察结果用光线跟踪方法检测表面和用三线性插值方法绘制表面图。结果实现虚拟内窥结果的可视化，研制出基于微机的虚拟内窥系统和对三维人体影像数据虚拟内窥的结果。结论虚拟内窥是实现医学虚拟诊断。
Objective To make experimental study on 3D human body virtual endoscope
systematically using 3D image data of a human body. Method The geometrical model and
locating of a virtual endoscope were built. By the model, we can view a virtual human body in
different directions and resolutions.Then, method of ray tracing for surface detection and
trilinear interpolation for surface rendering were applied to visualize the result of virtual
endoscope. Result A virtual endoscope system based on PC that uses the method were given
and a few virtual endoscope images of 3D human body image data were also presented.
Conclusion Virtual endoscope is one of the most hopeful methods for virtual diagnosis, virtual
therapy and virtual teaching.
