摘要
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。该技术采用微透镜阵列记录空间场景,空间任意一点的深度信息只需通过一次成像即可直接获得。Facet-braiding是三维全景图像中一种很重要的视觉现象,该现象造成图像失真,影响了图像的观看效果。Ref.6中Martinez-Cuenca从单个元素图像的角度对该现象进行了分析,现从三维重建的角度对该现象的出现与否进行对比验证。先用光学软件模拟深度优先、参考平面在无穷远处的传统Ⅱ成像系统,然后在该模拟系统中进行对比实验,结果并未出现Ref.6中提到的facet-braiding现象。该结果对Ⅱ的视角分析、物体的精确三维重建及空间分辨率分析具有重要意义。
Integral Imaging（II）is a technique capable of displaying three-dimensional images with continuous parallax in full natural color.Since micro-lens sheet is used in recording,only one recording is necessary in containing three-dimensional information.Facet-braiding effect is an important visual phenomenon,which induces distortions and impoverishes the integral image quality.In Ref.6 the facet-braiding phenomenon was analyzed in view of single elemental image by Martinez-Cuenca.In contrast,in this paper the phenomenon was verified from the 3D reconstruction.First the traditio-nal II system was modeled with optical software.Then the contrast experiment was drawn in the depth priority regime where the distance between the reference image plane and the reconstructed image is infinite.The facet-braiding effect was not presented in our modeled optical system.The result will play an important role in viewing angle analysis,precise 3D reconstruction and spatial resolution analysis.
