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。
立體視覺功能是宇航員、飛行員、高速車輛的駕駛員在身體檢查中必鬚檢查的項目。根據視覺生理理論,併參照軍用光學儀器通用規範,提齣一種應用現代計算機技術、虛擬光學技術實現的立體視覺檢查方法。詳細介紹瞭立體圖像對的設計。用計算機產生隨機點立體圖像對,左右圖像的視差越大,圖形離開揹景的距離也越大。通過計算機控製不同視差的立體圖像對生成,將計算機產生的立體圖用虛擬成像技術呈現在受檢人的眼前,定量檢測人眼的立體視能力。具有簡便易行、精度高的特點。大量實驗證明該方法應用在人體的立體視覺檢查中,能夠替代傳統的立體視覺檢查方法。

The function of stereovision is an important item which must be examined in the physical examination of as-tronauts,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 technolo-gy. 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 ste-reovision inspection of human body,can replace the traditional method of stereovision inspection.
