医学虚拟训练的视觉与触觉场景三维同步匹配

Synchronously matching of visual scene with haptic scene in three-dimensional space for medical training simulation

基于高精度虚拟中国人男性一号数据集和虚拟现实开发工具 Open Inventor,利用由主动式立体眼镜和力反馈设备构建的仿真平台,实现了视觉场景图和触觉场景图的三维同步匹配。论述了开发环境的具体要求,分析了视觉和触觉场景图三维同步匹配的实现策略,给出了三维同步匹配和注射模拟实验的仿真结果。结果表明,虚拟系统的视觉场景图和触觉场景图的三维同步匹配准确,可实时、快速实现视觉和触觉的立体模式医学虚拟训练。

Based on the high resolution dataset of Virtual Chinese Inventor, the visual scene graph and the haptic scene graph simulation system which integrated the active stereo glasses Male-No, 1 and the virtual reality development toolkit Open were matched in the three-dimensional （3D） space using the and the force-feedback device. In this paper, we described the developing requirements for medical training simulation, the implementation strategy for the synchronous 3D visualhaptic match was analyzed, and some valuable results of the experiments on 3D synchronous match and the simulated in jection were presented. The results demonstrated that the simulation system can provide synchronous 3D visual-haptic match, which can lead to the realistic medical training simulation.
