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.

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".
