项目摘要

We investigated the method to evaluate the binocular stereoscopic image systems using binocular disparity from the view point of visual function. We measured the accommodative response and vergence eye movement while viewing the stereoscopic system using parallax barrier type. And We also measured the accommodative response and vergence eye movement while viewing LED real target. The results obtained from those two experiments are :(1) The accommodation and vergence occured simultaneously with mutually closed relationship in stereoscopic display and real targets.i.e. there were no unbalance response in accommodation and vergence.(2) In stereoscopic image display, accommodation showed transient overshoot and unstable characteristics. In real target, we did not find those phenomenon.(3) There was no difference between vergence in stereoscopic display and in real target.(4) There were not large difference in amount of accommodation and vergence in the stereoscopic display and LED real target.(5) The accommodative response and vergence response were correspond to the position of reconstructed image in case of small binocular disparity. From these reults, we found the possibility that we can use accommodative response, its transient response and instability as the ruler to evaluate stereoscopic image. But vergence is not because the difference in stereoscopic and real target is small.To say exactly, we can not distinguish the influence of display type from its qualities, for example image resolution, viewing angle. In future, it is nessesary to investigate the influence of image condition and personality.

我们从视觉功能的角度研究了利用双目视差评估双目立体图像系统的方法。我们测量了使用视差屏障类型观看立体系统时的调节反应和聚散性眼球运动。我们还测量了观看 LED 真实目标时的调节反应和聚散眼运动。这两个实验得到的结果是：（1）立体显示与真实目标的调节和聚散同时发生，且关系密切。 (2)在立体图像显示中，调节表现出短暂的超调和不稳定的特性。在真实目标中，我们没有发现这些现象。（3）立体显示和真实目标的聚散度没有差异。（4）立体显示和LED真实目标的调节量和聚散度没有太大差异。（5）在双眼视差较小的情况下，调节响应和聚散响应与重建图像的位置相对应。从这些结果中，我们发现了利用调节响应、瞬态响应和不稳定性作为评价立体图像的标尺的可能性。但聚散度并不是因为立体目标与真实目标的差异很小。准确地说，我们无法区分显示类型与其质量的影响，例如图像分辨率、视角。未来有必要研究形象条件和个性的影响。
