摘　　要：立体视觉功能是宇航员、飞行员、高速车辆的驾驶员在身体检查中必须检查的项目。根据视觉生理理论,并参照军用光学仪器通用规范,提出一种应用现代计算机技术、虚拟光学技术实现的立体视觉检查方法。详细介绍了立体图像对的设计。用计算机产生随机点立体图像对,左右图像的视差越大,图形离开背景的距离也越大。通过计算机控制不同视差的立体图像对生成,将计算机产生的立体图用虚拟成像技术呈现在受检人的眼前,定量检测人眼的立体视能力。具有简便易行、精度高的特点。大量实验证明该方法应用在人体的立体视觉检查中,能够替代传统的立体视觉检查方法。The function of stereovision is an important item which must be examined in the physical examination of astronauts,pilots,or high speed vehicle drivers. A new method based on viewing physiology and general specification for military optical instruments is presented in this paper. It achieved with Computer technology and virtual optical technology. In this paper the design of stereo image pair to examine the stereo acuity is introduced in detail. The random-dot stereograms hided the binocular parallax are generated with computer program. The parallax in a pair of stereograms is bigger the distance between the pattern and its background is bigger. Using a computer program to control the different parallax in the stereo image pairs and showing them In front of the being tested person＇s eyes with a virtual optics,then the stereo acuity can be examined by watching different pairs of random-dot stereogram. This method has the characteristics of simple,high precision. Lots of experiments show that this method is successfully applied in the stereovision inspection of human body,can replace the traditional method of stereovision inspection.
