Abstract
The accurate detection of insulator profile of mine transmission line is the basis and premise of mine intelligent UAV (unmanned aerial vehicle) inspection, but it has not been effectively solved. In this paper, the mathematical model of traditional edge detection operator is first derivative operator: Robert operator, Prewitt operator, Sobel operator, and operators whose mathematical model is second derivative Laplacian operator, LOG operator, Canny operator and so on are studied comprehensively. These algorithms are applied to the insulator profile detection of transmission lines, and the experimental results are analyzed and compared.
