Detection Method of Insulator Based on Single Shot MultiBox Detector

Abstract

Insulators are the most common equipment in the power system, the failure of insulators will cause heavy economic loss to electric power companies, so it is very important to detect insulators effectively for inspecting their working states. This paper proposes a novel method to detect the insulators based on single shot multibox detector (SSD) in which discretizes the output space of bounding boxes into a set of default boxes over different aspect ratios and scales per feature map location. A large number of visible light images are used as experimental data in experiment, and the results show that this method can detect small-size insulators in complex background with high precision as well as low time cost.
