记录分辨率对Ⅱ三维重建分辨率的影响

Effects of Record Resolution on Ⅱ Three-dimensional Reconstruction Resolution

三维全景图像技术(Integral Imaging,简称Ⅱ)是一种能够记录和显示全真三维场景的图像技术。分辨率低一直是限制该技术发展的最重要因素之一,而其中记录分辨率对三维重建分辨率的影响尤其突出,但目前这方面的研究较少且与实际不符。在深度优先的Ⅱ系统中分析研究记录分辨率对Ⅱ三维重建分辨率的影响,推导出记录分辨率与深度的关系,并以实验验证所得结果。对Ⅱ成像系统优化参数设计、物体空间分辨率分析及未来三维电视的数据处理具有重要意义。

Integral Imaging （Ⅱ） is a technique capable of displaying three-dimensional images with continuous parallax in full natural color. Low resolution is always one of the most important factors which constrained the development of Ⅱ technology. The most prominent factor that affects the Ⅱ 3D reconstruction resolution is record resolution. But now the relative research is lack and inconsistency with the reality. We presented the effects of record resolution on the 3D reconstruction resolution in depth priority Ⅱ system. The relationship between record resolution and depth information was derived. And experiments were conducted to confirm our conclusions. The results will play an important role in optimum parameter design,spatial resolution analysis and data processing of the next generation Ⅱ-based 3DTV.
