The purpose of the paper is to solve the two problems for computer vision tracking. One is radial distortion and tangential distortion problem of Zhang Zhengyou calibration which makes great error and reduces the accuracy of the experiment.Another one is high redundancy problem for traditional neural network calibration. From the research,this paper put forward the algorithm of camera calibration using feedback regulation of neural network. There were three steps for the procedures of the research. First,it...
