%X Images with severe geometrical distortions,which are induced by camera lens and position, must be corrected before extracting quantitative m easurements.In this paper,we present a geometric calibration method for lens c amera by applying polynomial warping and bilinear interpolation,and discusses t he selection pattern of control points.First,we implement a general polynomial warping algorithm and a bilinear interpolation algorithm in Visual C 5 0,then we demonstrate that,for common optical lens,images with geometric dist ortions can be rectified with cubic polynomial warping method using only a few c ontrol points.This method is simple and practical,and can be used in camera-f ixed situations,such as operating table and on-line industry inspection,to ac quire lossless images.Practical application in lottery printing quality inspect ion shows that the method is reliable and valid.
