摘　　要：指出了达芬奇立体是近年来立体知觉机制研究的重要问题.以随机点为背景,考察了达芬奇立体知觉的形成与背景匹配加工的相关性.实验表明:在成对性刺激物中,当成对物体与背景深度之间的视差为零时,非成对物体的深度感显著地下降了.这提示,达芬奇立体知觉的形成包含背景匹配的加工.Da Vinci stereopsis has been an important issue in the research of stereoscopic vision in recent years. To investigate whether the background has been matched in the process of Da Vinci stereopsis formation,we conducted an experiment in which the random-dot stereogram was served as background. The result revealed that the depth perception of monocular region significantly reduced when the disparity between the paired object and the background was zero in paired stimuli. Our work suggests that Da Vinci stereopis formation may involve a matching process of background.
