【摘要】 目的：设计一种行之有效用于中远距离的立体视检查方法。方法：以新立体视觉检查（ＮＳＴ） 为样本研制计算机中远距离立体视觉检查仪（ＣＳＴ），分别在１ 、１．５、２、３、４ 、５ 米距离检查正常人７２ 例的交叉及非交叉立体视差。结果：各距离交叉视差的集中趋势分别为１．５、１ ．６、１．８、２．３ 、２．９、３ ．７“象素点”（ 下同） ，８０％ 范围值为１１．９、１１．９、１２．３、１３．２、１３．０、１４．７。非交叉视差的集中趋势分别为：１．６ 、１．７、１ ．９、２．６、３．５ 、４．７。８０％ 范围值为１１．９、１２．０、１２．５、１３．４、１５．４、１６．３。结论：ＣＳＴ可以检查中远距离立体视功能。更多还原

【Abstract】 Objective:To test the stereopsis of 72 normal subjects at a distance of one to five meters.Methods:Using the NST as an example,we designed the Computer Stereo Test (CST) for intermediate and long distances.Crossed and uncrossed disparities were tested at 1,1.5,2,3,4,and 5 meters.Results:The median apparent distance of crossed disparity cues were 1.5,1.6,1.8,2.3,2.9 and 3.7 meters for each respective distance.The figure of scales (80%) are 11.9,11.9,12.3,13.2,13.0,and 14.7 meters.The median apparent distance of uncrossed disparity are 1.6,1.7,1.9,2.6,3.5 and 4.7 meters,respectively.The figure of scales(80%) are 11.9,12.0,12.5,13.4,15.4 and 16.3 meters.Conclusion:CST can be tested for intermediate and long distance.更多还原
