人生活在三维空间内,对三维物体有感知能力。产生体感即相对深度知觉的主要信立息是双眼视差。所谓视差,原指左右两眼视网膜上分别接受到两个图像轮廓的水平位置差,通常用角度单位(分或秒)来表示。因此,体视是双眼的一种视觉功能。立体视锐度的测定是研究立体视觉的一项基础工作,可为正常儿童及青少年的立体视功能发育情况提供重要的基本数据。所谓立体视锐度是指在人的深度视觉巾可感知的最小深度差。以前国内外多用立体计测量,近年来随着电子计算机技术的广泛应用,而产生了随机点
People living in three-dimensional space, three-dimensional objects have the ability to perceive. The main belief that gives rise to somatosensory or relative depth perception is binocular parallax. The so-called parallax, the original refers to the left and right eyes were received two images of the outline of the horizontal position difference, usually with angle units (minutes or seconds) to represent. Therefore, stereoscopy is a visual function of both eyes. Stereoscopic acuity determination is a basic research of stereoscopic vision, which can provide important basic data for the development of stereopsis of normal children and adolescents. The so-called stereoscopic acuity refers to the depth of the human visual depth can be aware of the smallest depth difference. Previously used at home and abroad with three-dimensional measurement, with the widespread use of computer technology in recent years, resulting in a random point
