NEW METHOD OF CCD CAMERA CALIBRATION BASED ON COLLIMATOR
基于平行光管的CCD相机标定新方法

A new method to calibrate CCD camera was proposed.It consists of two-dimension rotate instrument,collimator and CCD camera.At first,through Hough translation and least squares image matching,the intersection point of crisscross fixed on collimator,which imaged on the CCD focus plane,was found,And then a linear regression of least squares was used to calibrate the inner orientation elements and the distorted parameters based on the non-linear distortion model of camera.Experimental results of this method reveal good performance in the application of aerial triangulation operation and digital mapping.
