摘　　要：由于胶订书籍不能完全平铺于扫描仪的玻璃板上,从而使得扫描图像产生非线性几何畸变,为此,提出一种对此类畸变图像进行横向畸变数字校正的方法,并详细介绍了实现该数字校正的算法。实验结果表明,此算法能够大大减小横边误差,使畸变图像得到很好的复原。A book bound with glue can not be put flat on the glass plate of scanner,resulting in nonlinear geometric dis-tortion in the scanned image.In this article,a digital method is proposed to correct the horizontal geometric distortion,and the algorithm is discussed in detail.Experiment on the algorithm shows that the geometric distortion is reduced greatly and the scanned image is recovered successfully.
