The Orientation Angle Detection of Multiple Insulators in Aerial image
Insulator is one of the important equipments on the transmission line, and its orientation angle detection is an important preprocessing step for accurate localization of insulator. This paper proposes a method of orientation angle detection of insulators in order to realize the orientation determination of multiple insulators in aerial image with complicated background. Firstly, extract sequential edge points and define their orientation angles of each linking contour in the preprocessed image. And secondly define the points with sign-Changing angle as candidate points. Finally, the accurate points can be picked up by RANSAC (RANdom SAmple Consensus) from candidate points, and the straight line which accurate points locate in is the main direction of the target. Experimental results verify that the proposed method has higher detection accuracy compared with the existing methods that can lay the foundations for the localization of multiple insulators in complicated background.
