AI-Driven High-Definition Glasses-free 3D Light Field Display with Large-Viewing-Angle

Glasses-free true 3D light field display delivers authentic 3D video experiences that closely mimic real-world scenes, which aligns with the natural way humans perceive the real world. With both physiological and psychological depth cues, it provides comprehensive 3D perceptual information, enabling more intuitive and holistic cognition. High-definition glasses-free 3D light field display with large-viewing-angle, requires breaking through limitations in the degree of freedom and precision of light control devices while balancing the spatial bandwidth product of display systems. This report presents our research on AI-driven high-definition glasses-free 3D light field display with large-viewing-angle based on AI-assisted design and calibration. A 65-inch 3D light field display is realized with a viewing angle exceeding 110 degrees, featuring accurate spatial geometric occlusion relationships. 110-inch 3D light field displays with the clear display depth of 3 m is demonstrated. AI introduces novel approaches to 3D light field video processing, significantly lowering the threshold for 3D light field content creation. Free-space 3D light field distributions is constructed, which enables aerial imaging-based dynamic glasses-free 3D light field displays.

AI驱动的大视角高清晰裸眼3D光场显示

裸眼真3D光场显示为观看者提供最接近真实场景的真3D视频，符合人们观看世界的真实感受，满足生理和心理的深度线索暗示，获取更完备的生理和心理的3D感知信息，实现更直观、全面的认知。实现大视角高清晰裸眼3D光场显示，需要突破控光器件控光自由度和精准度的限制，兼顾显示器件空间带宽积。报告介绍了研究团队在AI驱动的大视角高清晰裸眼3D光场显示方面的探索。通过AI辅助设计与校正，实现了65英寸的超过110度视角的3D光场显示，具有正确的空间几何位置遮挡关系；实现了110英寸3米清晰显示深度的裸眼3D光场显示。AI为3D光场视频的处理提供了新思路，降低了3D光场内容产生的门槛。构建了自由空间3D光场分布，实现了多种形态空气成像的动态裸眼3D光场显示。
