| 摘 要： | 采用改进两步法实现了摄像机的标定,并给出基于OpenCV算法,充分发挥了OpenCV的函数库功能。对两步标定法的改进是在原两步法得到摄像机参数值的基础上,用非线性优化算法对所有参数进一步优化,得到最终参数值,既提高了摄像机标定精度和计算效率,又无需对摄像机像面中心预标定,简化了标定过程。

| Abstract: | This article reports an improved two-step approach for carrying out video camera calibration with the algorithm based on OpenCV,which puts the function of OpenCV libraries into full play.The improvement on two-step calibration is to optimize all the parameters by non-linear optimal algorithm for obtaining the final parameters.It is based on the parameters of the video camera gotten from the old two-step approach.It improves the precision of the video camera calibration and calculation efficiency,and also si... |
