为了显示可以裸眼周视观看和具有悬浮特性且可触摸的立体图像,通过分析多种立体显示技术原理、应用范围及其优缺点,提出了一种新型的立体显示技术。电机带动定向屏旋转,将多投影机出瞳成像并形成空间的观察域,当观察者双眼位于观察域内时,无需佩戴眼镜即可观察到具有运动视差的立体图像,且此图像具有悬浮可触摸的效果。对系统中的关键技术进行了阐述,通过实验得到了观察距离为580mm、悬浮中心高度为150mm的立体图像。
In order to display stereoscopic 3D images that can be viewed from the naked eye and can be touched with the floating characteristics, a novel stereoscopic display technology is proposed by analyzing the principle, application range and advantages and disadvantages of various stereoscopic display technologies. The motor drives the orientation screen to rotate and image the multi-projector exit pupil to form the observation space of the space. When both eyes of the observer are in the observation area, a stereoscopic image with motion parallax can be observed without wearing glasses, and the image has a floating touch Effect. The key technologies of the system are described. The stereoscopic images with the observation distance of 580mm and the height of the suspension center of 150mm are obtained through experiments.
