Multi-resolution stereoscopic camera and display systems for reality enhancement

本研究旨在开发一种多分辨率立体相机及显示系统。图像分辨率表明，系统从中心到外围以一种循序渐进的方式恶化。我们进行了三个心理生理学实验来确定系统参数，所有的刺激都是虚拟空间中带有大量小球的图像。在实验1和实验2中，我们使用中心具有高分辨率区域和低分辨率环境的双分辨率图像来考察中心高分辨率区域的大小和外围低分辨率区域的恶化程度的影响。受试者观察原始全高分辨率图像一秒钟，然后观察原始或双分辨率图像一秒。然后，他们回答这两张图片是否相同。在实验3中，我们考察了被试是否能够区分原始的全高分辨率图像和经过处理的图像，即三倍分辨率、双分辨率和单分辨率低分辨率图像。实验结果表明，受试者无法从原始图像中分辨出三倍分辨率的图像。在此基础上，研制了三倍分辨率立体相机和显示系统。该系统有三个摄像头，每只眼睛有21、42和65个视角，并提供计算机生成的三倍分辨率图像。来自该系统的图像由惠斯通立体查看器呈现

This research aims to develop a multi-resolution stereoscopic camera and display system. Image resolutions indicate that the system deteriorates from the center to the peripheral in a step-by-step fashion. We conducted three pychophysiological experiments to determine the system parameters.All stimuli were images with numerous small balls in virtual space. In experiments 1 and 2,we used dual resolution images, which have a high-resolution area in the center with low-resolution surroundings, to investigate the effects of the size of the high-resolution area shown in the center and the degree of deterioration of the low-resolution area in the peripheral. Subjects observed the original allover high-resolution images for one second and then the original or dual resolution images for one second. Then they answered whether the two images were the same. In experiment 3,we investigated whether subjects could distinguish between the original allover high-resolution image and processed images, which were triple resolution, dual resolution, and mono low-resolution images. The results demonstrate that the subjects could not discriminate the triple resolution images from the original images.Based on the results of these experiments, a triple resolution stereoscopic camera and display systems were developed. This system has three cameras, which have 21,42,and 65 angles of view for each eye, and gives computer-generated triple resolution pictures. The images from the system were presented with a wheatstone stereoscopic viewer
