中文摘要：

提出了一种将改进的遗传算法和LevenbergMarquardt（LM）算法相混合优化的摄像机自标定方法。首先将Hartley定义的简化Kruppa方程转换为优化代价函数,然后利用改进的遗传算法和LM算法相混合的优化算法求优化代价函数的最小值,进而求得摄像机的内参数。实验结果表明,与单一的优化方法相比,该方法的标定精度得到了较大的提高。

This paper presented a new camera self-calibration method by combining an improved genetic algorithm（GA） with Levenberg-Marquardt（LM） algorithm.Firstly,translated the simplified Kruppa equation defined by Hartley into the optimized cost function.Secondly,calculated the minimum value of the optimized cost function by a hybrid optimization algorithm which combined the improved GA with LM algorithm.Finally,obtained the intrinsic parameters of the camera.The experimental results show that the accuracy of the pr...
