Abstract

The invention discloses an insulator contour detection method based on a hybrid ant colony algorithm, and the method comprises the following steps: carrying out the gray normalization of a target insulator image, generating a gray histogram, and carrying out the linear stretching and noise filtering of the gray histogram; using an ant colony clustering algorithm for insulator image segmentation, and using a particle swarm algorithm for parameter optimization of clustering center number and radius. According to the method, the target insulator image can be accurately segmented, support is provided for fault detection of the insulator, and normal operation of a power system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of insulator image recognition, and in particular relates to an insulator contour detection method based on a hybrid ant colony algorithm. Background technique [0002] At present, the scale of my country's power grid continues to expand. As a fault-prone device in the power system, insulators determine whether the transmission line can operate safely to a certain extent. Therefore, as a prerequisite for the detection of the operating status of insulators, the contour detection of insulators has always been researched. Hotspots; the traditional insulator profile detection method is usually the ground visual method, which not only has low accuracy, but also consumes a lot of time, manpower and material resources; in recent years, with the continuous development of drone technology and image recognition technology, no The application of man-machine inspection in power system is gradually popularized. The insulat...
