摘　　要：指出了唯一性约束是解决人类立体视觉和计算机视觉"对应问题"的一个最基本的原则,它规定,一只眼中的一个特征只能与另一只眼中的一个特征发生匹配.由于缺乏可靠的直接实验证据,这一原则一直受到质疑.为此,提出了一种超越Panum方案的"折线"刺激构型,和确认匹配发生的融合倾斜判据,对这一原则进行直接检验.实验发现:在"折线"Panum极限情况下,当立体知觉形成时,一只眼中的一条折线始终与另一只眼中的二条折线匹配,这表明在此种情况下,唯一性原则不成立.The uniqueness constraints that one feature in one eye can match only one feature in the other eye, it is a long time to be used as one of the most basic principles to solve the ＂corresponding problem＂ in human threedimensional vision and computer vision. However, because of the absence of direct experimental evidence, this constraint has been questioned. So, this paper proposes a novel ＂broken line＂ Panum stimulus configuration beyond the ＂straight line＂ Panum case, and a fusion criterion of slant perception in depth, and then directly exam the uniqueness constraint. It is found that one broken line in one eye always matches two broken lines in the other eye as perceive the depth in the ＂broken line＂ Panum＇s limiting case, which indicates that the uniqueness constraint dose not apply, but double match occurs in Panum＇s limiting case.
