The inspection of power transmission lines is one of many applications ofunmanned aircraft. This paper examines the effectiveness of using basic imageprocessing methods, finding their limitations in Matlab and assembling aunmanned aircraft. Two methodologies are proposed which have in commonfeatures like grayscale image conversion, Laplacian of Gaussian edge detection,application of Hough Transformation and creation of areas of interest around thetransmission lines. The first one extracts the areas from the image after processing a number of original images in order to detect successfully the lines. The second methodology focuses on the central part of the image, dividing it into three sections (smaller areas of interest) without having to locate the lines first. In the case of a broken line, the methodologies use special line features such as theircontinuity, resemblance and constant distance between them to distinguish themfrom other structures shown in the image, detecting their absence.
