Abstract: To obtain wide field of view and high resolution ratio, the calibration method and procedure of ballistic camera with multi-CCD system are presented, and the principle and composition of calibration system are also introduced. An analysis for system distortion and the relation of object-image with wide filed of multi-CCD is carried out on the basis of the camera mathematical model. Under the optimum conditions, each of the parameters is settled in the mathematical model by means of least square poly-regress method. Experimental results show that the azimuth angle measurement error is less than 10″and the elevation angle measurement error is less than 15″.
