Paper Abstract

Practical application of two types of method for CCD camera's image center measurement is researched. With regard to image center, pixels' distribution to image plane is still symmetrical even under the influence of lens distortion. Based on this, with direct optical method, the image center is determined by the symmetry of pixels' position in vertical and horizontal directions on image plane. With lens distortion based perspective projection method, a complete imaging model is built and image center is a key element of the model. Two kinds of main lens distortion are considered in the model. Test is carried out and the comparison is made for two methods. The second method's strong convergence property is verified.
