福娃的愿景:自动立体浮动图像显示
Fuwa-Vision: An auto-stereoscopic floating-image display
Hideaki Nii, Kening Zhu, Hiromi Yoshikawa, Nyan Lin Htat, Roland Aigner, Ryohei Nakatsu
摘要:
我们提出了这个概念,为多个用户建立一个简单交互式的自动立体显示,它不需要眼镜或机械运动部件。此系统可以用简单的结构在半空中投影自动立体图像。这就提供了一个适当的视图的立体对象的组合和真实物体。在此设置中,可以检测到的对象的位置,并允许与3D图像的相互作用。例如,它可以检测到的位置的蜡烛,并提供虚拟火焰的蜡烛仿佛是真火。这显示是由四部分组成,背光液晶显示窗(LCD),透明LCD,菲涅尔凸透镜的光学轴和头部跟踪系统对观众的位置。它控制光的方向。
We propose Fuwa-Vision, a simple interactive auto-stereoscopic display for multiple users, which does not require glasses or mechanical moving components. This system can project auto-stereoscopic images in midair with a simple s***cture. This pro-vides a proper view of the combination of stereoscopic objects and real objects. In this setup, it can detect the location of the object, and allow the interaction with the 3D image. For example, it can detect the position of the candle, and render virtual flame for this candle as if it were with real fire. This display is consist of four parts, backlighted Liquid Crystal Dis- play(LCD) , transparent LCD, the Fresnel convex lens on the opti-cal axis and the head tracking system for the viewer’s position. It control the direction of light precisely.
