Problems solved by technology

[0003] The inventors found that in the existing training methods for identifying defects of overhead transmission lines, in addition to the huge number of photos that are difficult to manually identify, the existing training platforms also have the problems of slow identification speed and low accuracy, which is prone to problems in the identification of overhead transmission lines. At the same time, the current training methods for the improvement of transmission line defect identification skills are mainly based on the learning of text descriptions in the regulations, and there are also image displays to strengthen the improvement of defect identification capabilities. However, the image library Limited, poor learning efficiency, cumbersome learning process, learning effect can not be verified

Embodiment 1

[0040] like figure 1 As shown, this embodiment provides an evaluation method for overhead transmission line defect identification training, including:

[0041] Obtain images related to overhead transmission lines;

[0042] Categorize and normalize the naming of acquired images;

[0043]Perform defect marking on classified and normalized named images; grid unmarked images and marked images according to the same requirements, perform subtraction operations on unmarked and marked images, obtain marked areas in marked images, and establish Database of marked area centers and radii;

[0044] Evaluate the assessment data in the training according to the database;

[0045] In this embodiment, the normalization of images is realized by classifying and naming the images. When processing images on this basis, targeted processing can be performed on the classified images according to names, defects, etc., which improves the processing of images. speed, and can improve the pertinence ...

Abstract

The invention provides an evaluation method and system for defect identification training of an overhead transmission line. The evaluation method comprises the following steps: acquiring an image related to the overhead transmission line; carrying out classification and standardized naming on the acquired image; performing defect marking on the classified and normalized named image; an unmarked image and a marked image are obtained, the unmarked image and the marked image are gridded according to the same requirement, subtraction is conducted on the unmarked image and the marked image, a marked area in the marked image is obtained, and a database comprising the center and the radius of the marked area is established; evaluating the assessment data in the training according to the database; through an image marking technology and processing of related images, standardization of a database for training is improved, targeted learning, training and daily training are carried out by utilizing the standardized database, basic skills of overhead transmission line defect identification are mastered, the defect identification speed and accuracy are improved, a solid foundation is laid for checking work, and the working efficiency is improved. No missing report of defects of the overhead transmission line is ensured, and false report is reduced.

Description

technical field [0001] The invention belongs to the technical field of online training, and in particular relates to an evaluation method and system for defect identification training of overhead transmission lines. Background technique [0002] In the context of building a new power system with new energy as the main body, in order to improve the stability and safety of overhead transmission lines, transmission line operation and maintenance personnel are required to timely discover the line body, accessories, etc. Defects and hidden dangers in facilities and channel environment, and take effective measures in time to eliminate defects and hidden dangers, so as to ensure the normal and stable operation of transmission lines and ensure power supply. In recent years, helicopters and unmanned aerial vehicles have been widely used in the daily inspection of transmission lines. Through close-up fixed-point shooting of helicopters and unmanned aerial vehicles, high-definition pho...
