Parameter Estimation of Motion Blurred ...

In recent years , the insulator water hot washing vehicle has become a new method to clear insulator pollution. The pollution of the insulator can be monitored, and the blurred image restoration is an important step for the insulator image pollution judgment. Under the assumption of uniform linear motion blurred image and from the point of view of the Fourier transform, this paper will take theoretical analysis of the stripe characteristics and the direction characteristic of insulator blurred image’s point spread function in frequency domain. It introduces the mathematical principles of the Radon transform and ideas and steps to estimate motion blur direction and blur scale . Aimed at cross-shaped bright lines in Fourier spectra of actual insulator blurred image, a sub-block algorithm is proposed. The experimental results show the effectiveness of the algorithm.
