Stereopsis is largely unperturbed by various types of eye, head, and target movements. Here, we used a simple setup to investigate the limits of a previously untested type of stimulus motion on stereoscopic depth perception. Clockwise and counterclockwise rotations of an autostereogram were used to describe the limits of stereopsis to roll-tilt. The result showed intact depth perception with stimulus rotation up to approximately 12 degrees, regardless of rotation direction and viewing distance, indicating a tolerant mechanism for stereoscopic processing by the human neural system.
立体视觉在很大程度上不受各种类型的眼睛、头部和目标运动的干扰。在这里，我们使用了一个简单的装置来研究一种以前未测试过的刺激运动类型对立体深度感知的限制。使用自动立体图的顺时针和逆时针旋转来描述立体视觉对滚动倾斜的限制。结果表明，无论旋转方向和观察距离如何，刺激旋转高达约12度时深度感知仍保持完整，这表明人类神经系统对立体视觉处理具有一种宽容机制。
