利用双眼视觉原理可以将由成对图片组成的平面图象看成立体的。立体图象可增添生活中的情趣,在科技文献中使用也很有意义。一、双眼立体视觉靠视觉产生的立体感,是一种颇为复杂的过程。它既有物理的,也有生理的和心理的作用。立体感,实质上就是一种空间纵深感。靠视觉产生的纵深感,倒不一定非用双眼不可,用单眼也行(理由从略),但最有效的立体视觉还得靠双眼。当两眼注视P_1点(图1)时,P_1的象P_1″恰成在左右两眼的黄斑中心,传到脑中,感到前方的P_1是唯一的。与此同时,对距双眼连线N_左N_右等远的另任一点P_2,由于成象于两眼黄斑同侧的对应位 Using the principle of binocular vision, a planar image composed of paired pictures can be considered as a three-dimensional image. Stereoscopic images can add to the taste of life, and it is also meaningful for use in scientific literature. First, the three-dimensional visual sense of stereo vision generated by the eyes, is a rather complicated process. It has both physical as well as physiological and psychological functions. Three-dimensional sense, in essence, is a sense of space depth. Depending on the sense of depth generated by the vision, it is not always possible to use both eyes. It is also possible to use a single eye (the reason is omitted), but the most effective stereoscopic vision has to rely on both eyes. When the two eyes P_1 point (Figure 1), P_1 like P_1 "just right and left eyes in the center of the macula, spread to the brain, feel the front of P_1 is unique at the same time, from the eyes of the line N _ Left N_ right away from any other point P_2, due to imaging on the same side of the two macular eyes corresponding bit
