摘要： 针对基于棱镜的单目立体视觉系统，提出了一种分析和选择系统参数的最优化方法.该方法可以使系统拍摄到的图像以最佳的位置满足立体视觉算法处理的需要.从系统的建立和参数的选择角度分析了单目立体视觉系统的组成.引入了一种计算系统成像区域的数学方法，使用空间直线来表示光线的传播，利用光的折射定理的向量计算方法，解出光线经过棱镜折射后的直线方程，通过空间直线的关系确定系统的成像区域.通过对该系统成像区域的重新定义，将成像区域与捕获的图像联系起来，从而选择最佳系统参数配置.

Abstract: A method for analyzing and optimizing the prism based singlelens stereovision system was proposed so that the pictures captured by this system were adequate for the application of stereovision. The stereovision system was firstly analyzed from the standpoint of system setup and parameters selection. Then a mathematical method was introduced to calculate the FOV of the prism based singlelens stereovision system. The proposed method used line in space to show rectilinear propagation of light. The vector calculation method of the refraction of light theorem was used to solve the equation of the straight line through the prism in order to determine FOV. By adding some restricted condition， the area of FOV was redefined and a detailed connection between FOV and capture picture was given to obtain the appropriate image pair for stereovision.

Key words: singlelens stereovision, prism, FOV, system parameters, optimization
