摘要
研究了最优化理论与方法在摄像机标定中的应用,并以两步法的第二步为例,详细介绍了如何根据最小化重投影误差这一非线性最小二乘问题求出所有标定参数的最优解,给出了用G uses-N ew ton法进行求解的具体步骤,并在M atlab下实现对一组初始数据的迭代优化。
The paper studies the application of the optimization theory and methods in camera calibration, and takes the second step of the two-stage technique for instance, introduces how to get the optimized calibration parameters through minimizing the re-projection error, which is a nonlinear least square question. The calculation procedure of the Guess-Newton method is provided, and a group of original data is optimized iteratly using the method in Matlab.
