空间知觉的透视理论

The Perspective Theory of Space Perception

空间知觉与人在观察时的认知过程和透视结构有关,它还涉及不同参照系统信号之间的连续转换,运动自我透视和运动时间透视与整体和局部透视类似。视觉输入以视网膜协调的方式进行编码,来自每只眼睛的网膜中心值需要整合并与眼睛位置和眼动的信号相混合,形成自我中心信号。自我中心信号进一步转化为一个三维协调系统- -自我中心参照系统。视觉系统的神经输出是地球中心信号。

Space perception concerns the cognitive process and perspective structure wh e n an object is observed. It also involves successive transformations of signal s with respect to different reference systems. Moving-ego and moving-time pe rs pectives are similar to 'global' and 'local' perspectives. The visual inpu t is encoded in terms of retinal coordinates. The retinocentric values from each e ye are required to be unified, and to be combined with signals for eye position and movement to from the geocentric signals. The geocentric signals are fu rther transformed into a coordinate three-dimension system -the geocentric fra me of reference. The neural outputs of the visual system are geocentric signals.
