基于频域平移的高分辨率光场显示仿真研究

High-Resolution Light Field Display Simulation Based on Frequency Domain Translation

针对光场显示中分辨率偏低的问题,提出了一种基于频域平移的仿真方法。通过搭建虚拟相机阵列对三维物体的光场信息进行采集,获得元素图像集合;在频域中通过平移,生成元素图像集合的位移信息;采用时分复用的方法,将原始的元素图像集合与频率平移后的信息进行融合,得到高分辨率光场显示结果。相较于传统方法,所提出的方法实现过程相对简单,计算速度快,并具有较高的显示质量,在光场显示仿真领域,具有较大的应用潜力。

In order to alleviate the low-resolution issue,a three-dimensional(3 D)display simulation method based on frequency domain translation has been proposed.A virtual camera array has been built to collect the light field information of 3 D objects to obtain the element array image(EIA).The shifted information of simulation EIA of 3 D object can be generated by translation.The simulation EIA has fused with the shifted data.The final 3 D display result can be obtained by time division multiplexing.Compared with the traditional methods,the proposed method is relatively simple,which has faster calculation speed and better display quality.And it has great development potential in the prediction and optimization of the light field display.
