基于多视图绘制的体视重现

Volume Reconstruction Based on Multiple Viewpoint Rendering

通过使用规则照相机几何获取的空间透视体生成对极平面图,用计算全息与图像处理技术产生一个全息立体图。在计算全息中采用了基于衍射的光栅条纹生成方法,将视场分为连续的8个区域,每个区域由一个空间频率不同的基本条纹衍射生成,然后用全息条纹实现简单景物具有视差的3D体视重现。

An algorithm of holographic stereogram display that can be implemented using compute generated holography(CGH)and imaging process through capturing The spatio-perspective volume by The ″regular shearing″ geometry of a camera is proposed.Illuminating this hologram by a plane wave creates the volume effect in the observer's eyes.In diffraction specific fringe computation of 3-D holographic imaging,computation of basis fringes is according to a point imaging.View field is divided into eight regions by basis fringes diffraction.Sequence parallax images can be transformed into hologram using basis fringes.Experimental results are presented.
