Power transmission line tracking method and system

Abstract

The invention discloses a power transmission line tracking method and system. The method comprises the steps of: utilizing a ratio operator to carrying out edge detection on an image, and obtaining an edge binary image; carrying out housh conversion on the binary image, outputting a straight line of a power transmission line, and storing hough space parameters of the currently output straight line of the power transmission line; combined with the hough space parameters of a straight line of the power transmission line, applying particle filtering for successively calculating hough space parameters of each subsequent video frame, carrying out line determination on the straight line of the power transmission line by utilizing a Bayes classifier, and obtaining a determination result indicating whether the straight line of the power transmission line is a right power transmission line. According to the invention, collected continuous video frames are used for carrying out power transmission line tracking, the detection efficiency and accuracy of the power transmission line are improved, and the Bayes classifier is utilized for carrying out line determination on the power transmission line obtained by tracking, so that the detection accuracy of the power transmission line is further improved.

Description

technical field [0001] The invention relates to the field of power detection, in particular to a transmission line tracking method and system. Background technique [0002] With the development of society and economy, high-voltage, high-power, long-distance transmission lines have become an important energy supply for people's daily life and national economic development. The geographical environment through which transmission lines pass is also becoming more and more complex, and is easily affected by the surrounding environment such as nature. Traditional manual inspection of transmission lines is not only time-consuming and dangerous, but can only detect simple defects such as the ground, the bottom of towers, and self-explosion of insulators. Therefore, using aircraft to inspect transmission lines has become an inevitable trend in the current power industry. [0003] The inventor found through many times of practice that because the transmission line towers often have u...

Traditional manual inspection of transmission lines is not only time-consuming and dangerous, but can only detect simple defects such as the ground, the bottom of towers, self-explosion of insulators, etc. Therefore, using aircraft to inspect transmission lines has become an inevitable trend in the current power industry

[0003] The inventor found through many times of practice that because the transmission line towers often have ups and downs due to terrain changes, and the line itself has a certain arc, so when using an aircraft to inspect the transmission line, it is necessary to manually control the cloud equipped with detection equipment. The platform or pod keeps the transmission line always within the viewing angle. Therefore, it will cause a high workload of the line inspector, and the high load work of the line inspector will lead to low efficiency and accuracy of transmission line detection.
