Limited available elemental image array resources may be the most severe bottleneck for the promotion and application of integral-imaging-based 3D display. We propose a nonlinear mapping method for the generation of an elemental image array to get a photorealistic pseudoscopic free 3D display based on the parallel light field reconstruction nature of the integral imaging system. All the light rays emitted from the display panel are classified into a corresponding parallel light field according to its direction, and all the parallel light fields are captured as orthogonal projections of the scene before synthesizing all the orthogonal projections using a nonlinear mapping method to form the final elemental image array. Preliminary optical experiments as well as ray optical analysis are conducted to prove the feasibility and validity of the proposed method. The proposed method can exploit most of the current 3D platform. It is an effective and efficient way to generate an elemental image array.
有限的可用元素图像阵列资源可能是基于集成成像的3D显示推广和应用的最严重瓶颈。我们提出了一种用于生成元素图像阵列的非线性映射方法，以基于集成成像系统的平行光场重建特性获得逼真的伪立体自由3D显示。从显示面板发射的所有光线根据其方向被分类为相应的平行光场，并且所有平行光场在使用非线性映射方法合成所有正交投影以形成最终元素图像阵列之前被捕获为场景的正交投影。进行了初步光学实验以及光线光学分析，以证明所提方法的可行性和有效性。所提方法可以利用大多数当前的3D平台。这是一种生成元素图像阵列的有效且高效的方法。
