The search for stereograms that reveal depth features to two eyes that are concealed from each alone commenced with announcement of the invention of the stereoscope by Wheatstone in 1838. The paired figures he presented to the eyes were mostly simple outline drawings of geometrical objects, in order to reduce or remove monocular indications of depth. One stereogram, consisting of dots, yielded depth without monocular recognition; later others did so with more complex stereograms. Most notably in 1960, Julesz achieved this with computer-generated random-dot stereograms. Prior to Julesz similar patterns were hand-made, photographed and paired to yield stereograms by Cajal, Mobbs, Kompaneysky, and Aschenbrenner. Wheatstone did not recognise the significance of his simple dot stereogram possibly because he was interested in representing objects rather than surfaces stereoscopically. Thus, it can be argued that the precursors of random-dot stereograms were produced by Wheatstone in his article describing the invention of the stereoscope.
1838年惠斯通宣布发明立体视镜后，人们开始寻找能向两只眼睛揭示单独一只眼睛无法察觉的深度特征的立体图。他向眼睛呈现的成对图形大多是几何物体的简单轮廓图，以减少或消除单眼的深度指示。一幅由点组成的立体图在没有单眼识别的情况下产生了深度；后来，其他更复杂的立体图也做到了这一点。最值得注意的是，1960年朱尔兹用计算机生成的随机点立体图实现了这一点。在朱尔兹之前，类似的图案是由卡哈尔、莫布斯、科姆帕内斯基和阿申布伦纳手工制作、拍摄并配对以生成立体图的。惠斯通没有认识到他简单的点立体图的重要性，可能是因为他对立体呈现物体而不是表面感兴趣。因此，可以说随机点立体图的前身是惠斯通在描述立体视镜发明的文章中制作出来的。
