Evaluation Method of Roundness Error of Riveted Hole Based on Machine Vision
Aiming at the problem of evaluating roundness error of aircraft riveting holes,a method of evalu-ating roundness error of riveting holes based on machine vision is proposed.In this method,CCD industrial camera is used to obtain the image information of riveted hole,the image is denoised by Gaussian filter,and the edge information is extracted by Laplacian operator.Finally,the minimum inclusion region method is used to fit the roundness and evaluate the error of the edge image.The results show that the mean roundness error of the riveted hole is 0.095,the mean square error is 0.09,and the relative error rate of roundness is 0. 002 6,which provides a feasible method for evaluating the roundness error of the riveted hole.
