摘要: 为了获得低成本超大屏幕自由立体显示器, 采用了DLP投影的技术方案. 分析了柱透镜光传输特性. 通过模拟透镜光路, 获得了立体视区图. 结合立体视区的交叉干扰现象, 推导出适合大屏幕立体显示的光栅参数. 针对显示器的最佳观看距离, 分析了虚拟摄像机架设间距和前后景极限位置的关系. 实现了约150in超大屏幕立体显示墙, 同时提高了显示系统的立体感和临场感.Abstract: To obtain a low cost super large panel auto-stereoscopic display system, 3D monitor based on DLP was proposed. Optical transmission property of lenticular lens was analyzed. By simulating light path of lens, the figure of stereo viewing zones was obtained. With the crosstalk of stereo viewing zones, the parameters of lenticular lens suitable for large panel auto-stereoscopic display were deduced. For the best observing distance, the relationship between virtual cameras' distance and the scene limit positions was analyzed. An about 150-inch-large panel stereo display wall with enhanced three-dimensional effect and telepresence of the monitor at the same time was made.
