Fengpeng Wang · Optical Technique · 2006
The process of the scanner obtaining bar code signal can be modeled as the convolution of the ideal bar code signal with the point spread function of scanner.Deconvolution is the best deblurring method.The regularization method of deconvolution is studied according to the characteristic of bar code signal in order to solve the ill-posed problem of deconvolution,the penalty item is constructed,and the computational regularization algorithm is proposed for the bar code signal recovery.The anti-jamming ability of the algorithm is tested in different instance by experiments.The experimental results show that the regularization algorithm of the restoration of bar code signal can restrain the noise effectively when it is eliminating the effect of the point spread function.
