Problems solved by technology
The problems of traditional manual inspection, such as poor effect, high labor cost and low work efficiency, are more prominent, which can no longer meet the requirements of power grid inspection.
Furthermore, some transmission lines are located in sparsely populated high mountains and large ridges far away from towns and traffic arteries. The transportation and inspection of transmission lines is difficult and the quality requirements are high.

The invention provides a power transmission line small hardware fitting defect detection method and device and a storage medium. The method comprises the following steps: obtaining a plurality of original power transmission line inspection pictures through shooting equipment, preprocessing the quality of the plurality of original power transmission line inspection pictures to obtain a plurality ofpower transmission line inspection pictures, integrating the plurality of power transmission line inspection pictures to obtain a power transmission line inspection data set, and dividing the power transmission line inspection data set into a power transmission line inspection training set and a power transmission line inspection test set; performing data enhancement processing on the power transmission line inspection training set to obtain a power transmission line inspection enhanced training set; constructing a Libra R-CNN model, and performing optimization processing on the Libra R-CNN model to obtain a Libra R-CNN optimization model; and training the Libra R-CNN optimization model according to the power transmission line inspection enhanced training set to obtain a small hardware fitting detection model. Compared with manual inspection, the power transmission line small hardware fitting defect detection method and device and the storage medium are more convenient, safer and moreefficient, can adapt to various types and scales of power transmission line aerial image small hardware fitting defects, and are high in detection precision and strong in model generalization ability.
Description
technical field [0001] The invention mainly relates to the technical field of equipment detection, and in particular to a method, device and storage medium for detecting defects of small metal fittings of transmission lines. Background technique [0002] With the rapid development of my country's power grid construction, at present, the scale of my country's power grid has leapt to the first place in the world. By 2020, the total mileage of transmission lines in my country will exceed 1.59 million kilometers. In order to be able to detect defects and faults of small fittings in the transmission line in time to effectively eliminate potential safety hazards and ensure the normal operation of the transmission line, the power sector needs to carry out regular or irregular inspections of the power line. At present, the main power line inspection methods include manual inspection, robot inspection, manned helicopter inspection, drone inspection, etc. The problems of traditional...
