Size and distance perception of visual object in 3D space was experimentally investigated on human subjects under the situation where vergence angle was the only useful cue for the perception. As an experimental equipment, 3D image projector system and a large (2.5m×2.5m) transparent screen was used. Subjects looked at a visual object on the screen through a liquid crystal binocular shutter. Figures for the right eye and left eye on the screen were switched alternately with the frequency of the binocular shutter. Inter figure separation was changed by a CG computer to present a distance stimulus. The subject manipulated a joy stick to adjust either the size or the distance of a test stimulus in order to reproduce the size or the distance of a memorized reference figure.In the first experiment, the size of the reference dot was memorized by a subject, and then a test dot with a different size and a different distance subsequently presented was readjusted by the subject to fit the memori … More zed size or distance. Accuracy of size reproduction proved to be poor in most of the subjects, while in the small number of the subjects the accuracy of size reproduction was obviously better than the others. Accuracy of distance reproduction also showed wide individual variation. Individual variation of distance reproduction accuracy was highly correlated to that of size reproduction. The fact suggests that the neural network responsible to the size perception is based on the distance cue obtained through vergence eye movement.Accuracy of size reproduction of motion defined edge object was investigated in the second experiment. No obvious difference from the accuracy of ordinary object was observed. Accuracy of size reproduction of motion defined edge proved to be highly correlated to that of distance reproduction. The finding suggests that size perception neural network in the brain process information of both ordinary object and motion defined object after their shape being processed. Less

在聚焦角为唯一有用线索的情况下，对三维空间中视觉物体的大小和距离知觉进行了实验研究。实验设备采用3D图像投影仪系统和一个2.5m×2.5m的大屏幕。受试者通过液晶双眼快门观看屏幕上的视觉对象。屏幕上的右眼和左眼的数字随着双眼快门的频率交替切换。图形间间隔由CG计算机改变，以呈现距离刺激。在第一个实验中，受试者记住参考点的大小或距离，然后由受试者重新调整随后呈现的具有不同大小和不同距离的测试点，以适应记忆…更大的ZED尺寸或距离。在大多数被试中，尺寸复制的准确性较差，而在少数被试中，尺寸复制的准确性明显好于其他被试。远距离繁殖的准确性也表现出较大的个体差异。距离繁殖精度的个体变异与大小繁殖的个体变异高度相关。这一事实表明，神经网络负责尺寸感知的基础是通过会聚眼球运动获得的距离线索。实验二研究了运动定义的边缘物体尺寸复制的准确性。与普通物体的准确度无明显差异。运动定义边的大小复制精度与距离复制的精度高度相关。这一发现表明，大脑中的大小感知神经网络在处理普通物体和运动定义物体的形状后，都会处理它们的信息。较少
