We study optical technologies for viewer-tracked autostereoscopic 3D display (VTA3D), which provides improved 3D image quality and extended viewing range. In particular, we utilize a technique-the so-called dynamic fusion of viewing zone (DFVZ)-for each 3D optical line to realize image quality equivalent to that achievable at optimal viewing distance, even when a viewer is moving in a depth direction. In addition, we examine quantitative properties of viewing zones provided by the VTA3D system that adopted DFVZ, revealing that the optimal viewing zone can be formed at viewer position. Last, we show that the comfort zone is extended due to DFVZ. This is demonstrated by a viewer's subjective evaluation of the 3D display system that employs both multiview autostereoscopic 3D display and DFVZ.
我们研究用于观看者跟踪自动立体3D显示（VTA3D）的光学技术，该技术可提供更高的3D图像质量和更宽的观看范围。特别是，我们针对每条3D光线采用了一种技术——所谓的观看区域动态融合（DFVZ），即使观看者在深度方向上移动，也能实现与在最佳观看距离时相当的图像质量。此外，我们研究了采用DFVZ的VTA3D系统所提供的观看区域的定量特性，发现可以在观看者位置形成最佳观看区域。最后，我们表明由于DFVZ，舒适区得到了扩展。这通过观看者对同时采用多视图自动立体3D显示和DFVZ的3D显示系统的主观评价得到了证明。
