Embodiment Construction
[0044] In order to enable those skilled in the art to better understand the solution of the application, the technical solution in the application will be clearly and completely described below in conjunction with the accompanying drawings in the application. Obviously, the described embodiment is only a part of the application Examples, not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0045] The existing transmission line hidden danger detection algorithm needs to design different detection methods according to different hidden danger types. Among them, traditional image processing methods such as color and texture analysis and background modeling require manual design of features, which not only require staff to be very familiar with their application fields and data, but also require a lot of debugging...

The application discloses a method for detecting hidden dangers of power transmission lines, which includes: obtaining a map to be detected captured by satellite inspection; inputting the map to be detected into a ground object classification model to obtain a classification result map output by the ground object classification model; according to the classification result map The distance between each object and the transmission line determines the hidden dangers of the line in each object; wherein, the classification model of the object is obtained through the following steps: S1, pre-marking different objects in the original remote sensing image, and obtaining the marked remote sensing image; S2, Establish a training set with labeled remote sensing images and corresponding original remote sensing images; S3, train the U‑Net network with the training set; S4, check the accuracy of the trained model through the verification set, if the accuracy is less than the preset value , adjust the parameters of the current model, return to step S3; if the accuracy rate is greater than or equal to the preset value, output the ground object classification model; solve the technical problem that different detection methods need to be designed for different types of hidden dangers in existing detection methods.
Description
technical field [0001] The present application relates to the technical field of line inspection, in particular to a method for detecting hidden dangers of transmission lines. Background technique [0002] As the demand for electricity in all walks of life continues to expand, the losses caused by accidental power outages are also increasing. Among them, overhead transmission lines are more susceptible to impacts because they are directly built on the ground and in direct contact with the surrounding environment, and accidents occur frequently. [0003] How to detect, deal with and prevent natural disasters and accidents that endanger transmission lines early, and ensure the normal supply of power at all times, has become the focus of attention. The hidden dangers that threaten the safety of transmission lines mainly include illegal buildings, super tall trees, construction vehicles, etc. Relevant departments need to continuously inspect the lines to search for possible hid...
