Internal consistency of local depth, slant, and curvature judgments was studied by asking participants to match two 3D surfaces rendered by different mixtures of 3D cues (velocity, texture, and shading). We found that perceptual judgments were not consistent with each other, with cue-specific distortions. Adding multiple cues did not eliminate the inconsistencies of the judgments. These results can be predicted by the Intrinsic Constraint (IC) model according to which the perceptual metric local estimates are a monotonically increasing function of the Signal-to-Noise Ratio of the optimal combination of direct information of 3D shape (Domini, Caudek, & Tassinari, 2006).
通过要求参与者匹配由不同3D线索（速度、纹理和阴影）混合呈现的两个3D表面，研究了局部深度、倾斜度和曲率判断的内部一致性。我们发现，感知判断彼此不一致，存在特定线索的扭曲。添加多个线索并不能消除判断的不一致性。这些结果可以由内在约束（IC）模型预测，根据该模型，感知度量局部估计是3D形状直接信息最佳组合的信噪比的单调递增函数（多米尼、考德克和塔西纳里，2006年）。
