摘要
人的立体视觉产生的原因是人的双眼同时观看物体时在左右眼的视网膜上形成的像存在像差。依据仿生学原理,只要给双眼提供观察物体时存在像差的同步图像信息,就可以得到立体图像。传统的立体成像方法都需要借助工具才能观察到立体图像,而柱镜光栅成像法不需要借助工具,用肉眼直接观看就可以得到立体图像。柱镜光栅成像法应用了柱镜光栅对光线的折射作用,使平面图像上各像点发出的光只能按特定的方向出射,而不是向四周出射,这样具有像差的同步图像信息就可以分别进入人的左眼和右眼,经过大脑的分析处理后就得到了有一定深度感的立体图像。
The reason that a person has 3D vision is the error in viewing. Based on bionics, so long as two eyes can feel the synchronization pictorial information, a person may see the 3D image. The traditional methods of 3D imaging need tools to observe the 3D images, but the law of the 3D imaging with lenticular grating can directly observe the 3D images by naked eyes. The lenticular grating can refract a light, so the light from the 2D images spread only at the specific direction, not at around direction. When the synchronization pectorial information enter a person＇s left eye and right eye independent, a person can obtain the 3D images by brain analysis.
