基于光场扫描的真三维立体显示系统的开发

Development of Real 3D Display System Based on Light Field Scanning

近年来,计算机视觉领域出现了一种新型的三维显示技术,即光场三维显示技术。基于光场扫描的真三维立体显示系统通过重构物体光强的空间分布,减少了信息冗余,采用高速投影仪、定向散射反射镜和高速旋转马达等设计而成。通过分析光场三维显示原理和系统工作原理、显示系统架构和立体成像原理等,详细论述了显示系统开发的可行性,并通过实验证明了当达到一定投影输出功率和马达旋转功率时可实现立体成像。观测者可360度裸眼观测立体图像,并且无需佩戴任何辅助工具。

In recent years,the light field 3 D display technology,an innovative 3 D display technology,has been proposed in the field of computer vision.This technology is a real 3 D display system based on light field scanning.By restructuring the spatial distribution of light intensity,the amount of excessive information will be reduced.In order to design the system,high speed projector,directional scatter reflector,high speed spinning motors and so on will be applied into the system.The feasibility of the display system will be analyzed based on the principles of lithe field 3 D display and its system,display system structure and stereo imaging.The experiment proves that when the output power of the projector and rotary power of the motor reach a certain level,the dimensional imaging will be achieved.Without any goggles or tools,observers could watch the 360 dimensional images with their naked eyes.
