Optimized Image Synthesis for Multi-Projector-Type Light Field Display

Abstract

Conventional light field displays suffer from the problem that severe distortion is perceived when the scenes are reconstructed far from the focused screen, due to the angular information loss in the reconstruction process. We introduce a weighted average optimization to the image synthesis process, aiming to tradeoff the reconstructed depth range and the image sharpness without changing the hardware configuration, particularly for multi-projector-type light field displays. The proposed optimization evaluates the lost angular information and reallocates them in the rendering process. The RMSE evaluation on the optimization performance is implemented. The experimental results show that after the optimization the display offers more accurate reconstruction than before. Besides, a subjective experiment is implemented to further validate the effectiveness of the optimization. We envision this optimization being applied to various multi-projector-type light field displays, despite of the arrangement of projectors and the shape of the screen.
