For the blurred image of insulator based on aerial images,Lucy-Richardson,Least squares,Blind deconvolution and Wiener filtering is adopted respectively on the original blurred image,and all kinds of rehabilitation results is compared and analyzed,an improved Wiener filtering method is proposed,that is Laplacian is applied to carry out linearity sharpening filtering treating on Wiener filtering restored image,and strengthen the edge information of insulator and the contour feature of the image.Then the working state of the insulator can be easily observed.At last,the vector norm sum of image gray gradient and G k' is introduced to evaluate the restored image quality.The test results show that the improved Wiener filtering method can improve the image definition and can be a feasible method to distinguish insulator' s trouble accurately.
