一种低成本视差立体特效设计与实现

A Low-cost Design and Realization for Stereo-pair Effect on Normal Screen

提出一种可以在普通屏幕上实现的低成本双目视差立体特效原理,通过将2幅计算机生成的视差不同的图像用2次平面镜反射叠加到人的左右眼而呈现立体效果。讨论了实现该特效的视觉原理,证明并验证了调整成像系统软件参数可以让视差和透视产生的距离感一致,设计并验证了光学设备"双目潜望镜"可以平衡双目汇聚和焦距,最后展示了所作的软件、设备和效果图像。

In this paper,the authors present a method which can create a super 3D effect by using two pairs of mirrors to make two eyes see two different images,each of which is generated by an original 3D engine with two different virtual observers.The principle of vision,with which the effects can work,is breifly described.It is proved and tested that it is possible to get the same feeling of depth from both disparity and perspective as deep clue by adjusting software perameters.A light processing equipment is designed to balance the feel of depth from binocular convergence and focal length.Finally,the software,equipment and image effect were exhibited.
