Abstract  
A method to improve the brightness uniformity of light field three-dimensional display was proposed in order to solve the problem of uniformity of integral three-dimensional display. The method increased the brightness uniformity by modulating the brightness of RGB channels of each projector respectively. The prototype was mainly composed of a projector-array consisted of 76 mini projectors and a light field modulation screen. The experiments verified the proposed method. Results indicate that the method can overcome the deficiencies of the uneven brightness of light field three-dimensional display based on multi-projector.

集成光场三维显示亮度均匀性校正方法

针对集成光场三维显示亮度不均匀的问题,提出基于光场重构的提高三维显示亮度均匀性的方法. 该方法通过调制每台投影机投射画面各颜色通道的各处亮度,从而提高三维画面的整体亮度均匀性. 实验样机主要由76台小投影机构成的投影阵列和光场调控屏幕组成,通过实验验证了提出的改善亮度均匀性的方法. 实验结果表明,采用该方法可以克服现有基于多投影的光场三维显示中画面亮度不均匀的缺陷.
