Multi-resolution stereoscopic camera and display systems for reality enhancement

本课题旨在开发一种多分辨率立体摄像及显示系统。图像分辨率表明系统从中心到外围逐步恶化。我们进行了三次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有许多小球的图像。在实验1和2中，我们使用双分辨率图像，即中心有一个高分辨率区域和低分辨率环境，来研究中心显示的高分辨率区域的大小和外围低分辨率区域的退化程度的影响。受试者先观察原始的全分辨率图像1秒，然后再观察原始或双分辨率图像1秒。然后他们回答这两个图像是否相同。在实验3中，我们考察了被试是否能够区分原始的全分辨率图像和处理后的图像，即三分辨率、双分辨率和单低分辨率图像。结果表明，被试无法将三分辨率图像与原始图像区分开来。在此基础上，研制了三分辨率立体摄像机和显示系统。该系统有三个摄像头，每只眼睛分别有21、42和65个视角，并提供计算机生成的三倍分辨率图像。系统的图像用惠斯通立体显示器显示

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
