基于CHAI3D的虚拟手术训练系统研究

Research on Virtual Surgical Training System based on CHAI3D

CHAI3D具有强大的力觉渲染能力,但相关应用并不广泛,为此,在CHAI3D平台下搭建虚拟手术场景,导入手术台及人体的3ds文件,通过属性设置、纹理贴图、视角变换增强系统的视觉表现;详细给出CHAI3D平台下虚拟手术场景设计的具体流程及其在虚拟训练系统中的力觉渲染优势;最后呈现了不同视角下的虚拟手术训练系统实例。关键程序段及训练系统实例充分体现了CHAI3D在虚拟现实场景创建及人机交互方面的便利性与高效性,为初学者快速入门提供了参考。

CHAI3D has powerful force-sensing rendering capabilities, but its related applications are not extensive. In view of this problem, this paper proposes to build a virtual surgical scene on the CHAI3D platform. The 3ds files of operating table and human body are imported, and visual representation of the system is enhanced through attribute setting, texture mapping, and perspective transformation. This paper elaborates the specific process of virtual surgical scene design on CHAI3D platform and the force rendering advantage of CHAI3D in virtual training system. Finally, virtual surgical training system from different perspectives is presented. The key program segments and training system examples fully reflect the convenience and efficiency of CHAI3D in the creation of virtual reality scenes and human-computer interaction, and the proposed system provides a reference for beginners to get started quickly.
