3点一维标定杆的摄像机标定，求得内外参数矩阵，实现三维重建。-Camera calibration of 3 point one-dimensional calibration bar, internal and external parameter matrix is obtained, the realization of three-dimensional reconstruction.

本部分代码只是提供了基础矩阵及摄像机焦距部分的代码。其中基础矩阵的求解用到的数据，是图像匹配得到的点对-This section provides the basis matrix code only part of the code and the focal length of the camera. Which is used to solve the fundamental matrix of the data is obtained by image matching points
