摘　　要：主要研究的是相机标定和双目定位问题。为了对相机进行标定,根据仿射变换理论,运用图像处理方法找到若干对应点,再用Lingo软件通过最小二乘法标定了数码相机的内外部参数,建立起了靶标上的点与像点之间的对应关系。通过合理的假设和算法优化,减小了计算机求解的时间复杂度和空间复杂度,运算较快而且结果精度较高、鲁棒性好。This article mainly researches the demarcation of the camera and the positioning of eyes. In order to realize carry out the demarcation of the camera, we must try to find certain corresponding points by using the affine transformation theory and image processing methods. Then we manage to figure out both the internal and external parameters of digital camera through east squares. In this way, corresponding relationships can be established between points on the target and points on the image. By using reasonable assumptions and optimization algorithm, we manage to reduce the time and space complexities of the algorithm and realize more accurate results in a shorter period of time.
