摘要
介绍了图像校正的两种算法:透视变换方法和控制点变换方法(双线性插值方法),分析了这两种方法的特点和差异。并就这两种方法在二维条码图像校正中的应用进行了讨论,得到的结论是:透视变换方法在实际拍摄的条码图像校正中较控制点变换方法更精确。
In this essay,two ways of two-dimensional image rectifying algorithms are introduced.One is the control-point transformation;the other is the projective transformation.After analyzing these two methods from different standpoints,including specialties and differences,and discussing their application in two-dimensional barcode image rectification,the conclusion is that the projective transformation is more precise than the other one in rectification of actual shooting barcode image.
