摘　　要：阐述立体视觉及双目视差原理。采用双中心投影算法,介绍立体图像对生成的有关计算公式,详细描述OpenGL立体显示一个立方体的步骤,并借助红绿滤光眼镜观察生成的立体图像对。结果表明,采用双中心投影算法可以得到较好的立体效果,可广泛使用于建筑物和视景漫游等多种场合。This paper explains the principle of the stereoscopic vision as well as the binocular parallax.Using dual-center projection algorithm,introduces related calculating formulas of the stereo pair generation,describes steps of a cube stereo display in OpenGL in detail,and observes the stereo pair with the help of red-green filter glasses.The result shows that better stereo display effect can be achieved by using of dual-center projection algorithm.This technology can be used wide- ly in building and roam about field of vision and many other occasions.
