We present anl omnidirectional 3D autostereoscopic aerial display with continuous parallax. Integral photography (IP) combined with polyhedron-shaped aerial imaging plates (AIPs) is utilized to achieve an extended view angle of 3D aerial images. With optical theoretical analysis and an aerial in situ rotation design, a 3D aerial display with an enlarged viewing angle is realized. In particular, the proposed 3D aerial display can realize any assigned angle within 360 deg. We also optimize the aerial display with artifact image removal and floating image brightness analysis. Experiments are performed to prove the 3D aerial display with full-motion parallax, continuous viewpoints, and multiplayer interaction. The proposed system is an attractive prospect of non-contact interaction and multi-person collaboration.
我们展示了一种具有连续视差的全向3D自动立体空中显示器。利用积分摄影（IP）与多面体形状的空中成像板（AIP）相结合，以实现3D空中图像的扩展视角。通过光学理论分析和空中原位旋转设计，实现了具有更大视角的3D空中显示器。特别地，所提出的3D空中显示器可以在360度范围内实现任何指定角度。我们还通过去除伪像图像和分析浮动图像亮度来优化空中显示器。进行实验以证明具有全动态视差、连续视点和多人交互的3D空中显示器。所提出的系统在非接触交互和多人协作方面具有诱人的前景。
