We introduce a near eye light field display proposal to reconstruct a light field in high synthesis speed by utilizing the multi-layer light field display technology and human visual features. The resolution distribution of the reconstructed light field is set to be identical to human visual acuity which decreases with the increasing visual eccentricity. We compress the light field information by using different sampling rates in different visual eccentricity area. A new optimization method for the compressed light field is proposed, which dramatically reduces the amount of calculation. The results demonstrate that the acceleration of the proposed scheme is obvious and escalates when the spatial resolution increases. The synthesis scheme is verified and its key aspects are analyzed by simulation and an experimental prototype.
我们提出一种近眼光场显示方案，通过利用多层光场显示技术和人类视觉特征，以高合成速度重建光场。重建光场的分辨率分布设置为与人类视力相同，人类视力会随着视觉离心率的增加而降低。我们在不同的视觉离心率区域使用不同的采样率来压缩光场信息。提出了一种针对压缩光场的新优化方法，该方法显著减少了计算量。结果表明，所提方案的加速效果明显，并且随着空间分辨率的提高而增强。通过仿真和实验原型对该合成方案进行了验证，并分析了其关键方面。
