摘要: 本工作的目的是希望了解立体感形成时双眼图象空间频谱的融合规律。我们利用不同质地的两套随机点立体图对,经过不同空间频带(低通、高通、带通)的光学滤波处理,然后将滤波后的图象作各种左右眼搭配观察。得到: 1.同样滤波的立体图对均能形成立体感; 2.不同质地的立体图对,空间频带搭配相同,但观察结果并不完全相同。 3.目前我们尚不能用立体图对的两个图像的空间频带是否重叠来了解两眼融合的规律。

Abstract: We attempted to understand the rule of fusion on the spatial frequencydomain in binocular stereopsis.Two sets of random-dot stereograms withdifferent texture were optically filtered by low,high and band pass filters.Filtered stereograms were paired in various combinations and examined undera stereoscope to see if any depth could be perceived. We observed that: 1. All the stereograms that passed the same filter could produce stereopsisperfectly. 2. Generally speaking,two sets with different texture have commontendency but in some cases they gave different results. 3. Sofar the overlap of spatial frequency spectra between the twohalf pictures of a stereogram could not be simply used as a rule to explain thefusing mechanism of stereo perception.
