Abstract A large viewing angle floating three-dimensional (3D) light field display based on spatial data reconstruction (SDR) algorithm is presented. It consists of the 3D light field display unit (LFDU) and the floating display unit (FDU). With the time-sequential directional backlight system, LFDU can provide 3D scenes with a large viewing angle in the horizontal direction. Based on FDU, the floating display has a large off-screen display depth, and the SDR algorithm is introduced to improve the 3D image quality. Combining the SDR algorithm with the time-sequential directional backlight system, a large viewing angle and image quality enhanced floating 3D light field display is realized. For the demonstrated floating 3D light field system, the floating 3D images can be reconstructed by the optical system within the viewing angle of 60 degrees. The feasibility of the proposed display method is verified with experimental results.

基于空间数据重构（SDR）算法的大视角浮动三维光场显示

摘要 提出了一种基于空间数据重构（SDR）算法的大视角浮动三维（3D）光场显示。它由3D光场显示单元（LFDU）和浮动显示单元（FDU）组成。LFDU采用时序定向背光系统，可提供水平方向大视角的3D场景。基于FDU，悬浮显示具有较大的离屏显示深度，并引入SDR算法提高3D图像质量。将SDR算法与时序定向背光系统相结合，实现大视角和画质增强的浮动3D光场显示。对于演示的浮动3D光场系统，光学系统可以在60度视角内重建浮动3D图像。
