| 摘 要： | 为了不受限制地在三维空间中直接观测体数据三维可视化结果，并且进行非接触式交互，提出了一种空中显示和虚拟交互的体绘制方法，将空中显示和虚拟交互结合应用到光线投射体绘制算法中，并在此基础上设计了一种体数据空中显示和虚拟交互的系统.实验结果表明医学影像体数据绘制图像能够很好在空中显示，而不依赖于任何的显示载体，空间真实感强烈.同时，能够通过体感感知检测手势实现非接触式交互，交互方式灵活自然，对观测者限制小.

| Abstract: | In order to directly observe the three-dimensional visualization results of volume data in three-dimensional space and perform contactless interaction, a volume rendering method was proposed to realize the aerial display and virtual interaction. Applying the aerial display and virtual interaction to the ray casting volume rendering algorithm, a system was designed for drawing aerial display and virtual interaction of volume data. The experimental results show that the medical image data can be displayed in the air well without relying on any display carrier, and the spatial reality is strong. Meanwhile, it can realize non-contact interaction through the sensory perception detection gesture. The interaction mode is flexible, natural and less limited to observer |
