Abstract

A new two stage camera calibration based on Zhang Zhengyou method is proposed to solve the distortion of fish eye lens.Initial parameters are solved as a closed form solution,which are further refined by using non linear least square method,the extrinsic and intrinsic parameters are got,the robustness of initial value can be improved and the tangential distortion is taken into considertion.The proposed method compares with the Zhang's method converges fast and has anaccuracy of 1.2σ.

张氏摄像机标定方法的改进研究

针对鱼眼镜头畸变问题，提出了一种基于张正友方法的两级摄像机标定方法。将初始参数求解为封闭解，利用非线性最小二乘法对其进行细化，得到了系统的外在参数和内在参数，提高了系统初值的鲁棒性，同时考虑了系统的切向畸变。与张氏方法相比，该方法收敛速度快，精度为1.2σ。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
