该论文提出了一种用于双层3D分解显示的光场分解处理器,能够以31fps的帧率处理7×7视角的高清光场,实现全视差裸眼3D观看体验。通过将光场分解为双层显示视图,解决了传统裸眼3D技术在景深、视场角和分辨率之间的权衡问题。
provides a fullparallax glasses-free 3D viewing experience. Compared to other autostereoscopic techniques, factored displays provide greater depth of field, larger field of view, and smoother perspective switching without sacrificing image resolution. Figure 33.3.1 shows an example: a light field consisting of 7×7-perspective multi views (MVs) is factorized into a set of dual-layer display views (DVs), and displaying the front and rear DVs on two corresponding LCDs can multiplicatively approximate the light field for 3D vision. A higher rank of factorization generates more frames for time-multiplexed display and can improve 3D fidelity with more computation. However, the light-field factorization demands massive memory bandwidth and large computation complexity and becomes
