Embodiment Construction

[0037] Below in conjunction with accompanying drawing and embodiment the present invention will be further described

[0038] Such as figure 1 As shown in the figure, a control algorithm and process for a UAV to automatically follow the route flight and patrol inspection:

[0039] 1. The UAV takes off vertically, and the flight control unit processes the data in the machine vision unit in real time

[0040] 2. The machine vision unit sends the image in the transmission line to the image processing module. The image processing module first uses canny edge detection on the image to obtain the contour image, and then uses the hough transform in OpenCV to detect the transmission line in the contour image to obtain Each transmission line is at the start point and end point of the image, and the width of the transmission line in the image is obtained at the same time. The machine vision unit calculates the position and direction of each power transmission line in the image and the...

Abstract

The invention discloses a multi-rotor-wing unmanned aerial vehicle for automatic routing inspection of a power transmission line and a method thereof. The unmanned aerial vehicle is composed of a machine vision unit, a flight control unit, a route shooting unit, and a battery power supply unit; and the machine vision unit and the route shooting unit are connected with the flight control unit. The machine vision unit captures image information of power transmission lines in real time, calculates positions and directions of all power transmission lines in the image as well as the relative distances of all power transmission lines in the image according to the captured image information, and sends the data to the flight control unit to stabilize the position, direction and height of the unmanned aerial vehicle relative to the power transmission lines, so that the unmanned aerial vehicle can fly in parallel to the route. The route shooting unit is used for obtaining image information of the power transmission lines when the unmanned aerial vehicle flies in parallel to the route. Therefore, accuracy and security of routing inspection of power transmission lines by the unmanned aerial vehicle can be improved; the stability of the shot picture can be enhanced; and the manpower cost for routing inspection by the unmanned aerial vehicle can be reduced.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle transmission line inspection, in particular to a multi-rotor unmanned aerial vehicle capable of automatic inspection of transmission lines and a method thereof. Background technique [0002] In 2020, the total length of China's transmission lines may exceed 1.59 million kilometers, and the inspection of transmission lines is an important and indispensable work to ensure safe and reliable power supply. In recent years, with the development of remote control drone technology, it has become technically feasible to use drones to inspect power lines. [0003] At present, compared with the previous manual inspection method, the efficiency of the remote control drone inspection method in the field of electric power inspection has been greatly improved, but in the line inspection, the remote control drone method is still difficult to stabilize. Following the transmission line, it is difficult to gu...
