摘要
提出一种用于视觉检测的快速高精度立体匹配算法．利用投影和透视变换理论以及矩阵转换知识建立了摄像机数学模型及双目视觉传感器模型，并给出摄像机模型中各种参数的求解方法；在外极约束理论的基础上，提出了外极斜率匹配方法，从而实现空间光条快速精确匹配．实验取得了令人满意的结果，并且该项技术已成功地应用于国家“８６３”重点攻关项目．
A fast precise algorithm for stereo stripe matching is presented.The mathematical model of a camera is established by using the projective and perspective theory and the matrix transformation theory.A calibration method of camera parameters is introduced.An epipolar shope matching method for the stereo stripe is proposed based on the epipolar constraint.The satisfactory result is derived from the experiment.This technique is successfully utilized in the national “863” project.
