摘要
运用OpenGL与3DMax建模,立体视觉与四元数旋转的技术,实现红外光虚拟手术刀的应用.首先,利用红外光追踪与立体视觉测距结合获得外部设备的空间坐标信息,然后映射到计算机已构建的虚拟手术刀模型,通过四元数实现模型的空间旋转,最后实现虚拟手术刀在虚拟手术场景中的应用.实验表明,该应用运用在虚拟医学外科手术切割中,有效仿真手术刀进行人机交互手术切割操作.
This paper mainly presents a virtual infrared scalpel with several techniques including OpenGL and 3DMax, stereoscopic vision and the quaternion. Firstly, it obtains the 3-d information of the virtual surgical knife with infrared light using the stereoscopic and infrared tracking. Secondly, it reflects the information to the scalpel modeling based on the OpenGL and 3DMax and rotates with the quaternion. Finally, it builds a virtual infrared scalpel. Experiment result demonstrates that the system can be applied to the surgery operation effectively for the interactive processing.
