We report four experiments that investigated the representation of novel three-dimensional (3D) objects by the human visual system. In the first experiment, canonical views were demonstrated for novel objects seen equally often from all test viewpoints. The next two experiments showed that the canonical views persisted under repeated testing, and in the presence of a variety of depth cues, including binocular stereo. The fourth experiment probed the ability of subjects to generalize recognition to unfamiliar views of objects previously seen at a limited range of attitudes. Both mono and stereo conditions yielded the same increase in the error rate with misorientation relative to the training attitude. Taken together, these results support the notion that 3D objects are represented by multiple specific views, possibly augmented by partial viewer-centered 3D information.
我们报告了四项实验,这些实验研究了人类视觉系统对新型三维(3D)物体的表征。在第一个实验中,展示了从所有测试视角均等出现的新型物体的标准视图。接下来的两个实验表明,标准视图在重复测试以及存在各种深度线索(包括双目立体视觉)的情况下仍然存在。第四个实验探究了受试者将识别推广到先前在有限视角范围内看到的物体的不熟悉视图的能力。单眼和立体视觉条件下,相对于训练视角的错误定向都会导致错误率同样增加。综合来看,这些结果支持了这样一种观点,即三维物体由多个特定视图表征,可能还辅以部分以观察者为中心的三维信息。
