摘　　要：在对图像扫描矢量化的过程中不可避免地要出现误差,这就要求我们对其进行图像纠正。根据误差的不同,我们可以选取不同的方法进行图像纠正,如赫尔默特、仿射变换、线性变换、二次变换及三次变换等。本文对这些变换进行一一分析与探讨,从而确定在适当的情况下选择相匹配的图像纠正方法。In the image scanning victimization process is inevitable to occur errors.This requires us to correct its image,depending on the image to correct the error; we can also choose different methods,such as Helmert,affine transformation,linear transformation,secondary transformation and third transformation.And we will be the body of one of these transform analysis and research,and ultimately choose the appropriate image remedies in appropriate circumstances.
