Photovoltaic panel hot spot positioning method based on unmanned aerial vehicle and thermal imaging

Abstract

The invention discloses a photovoltaic panel hot spot positioning method based on an unmanned aerial vehicle and thermal imaging. The method comprises the following steps of: measuring the position information of a photovoltaic module through a GPS positioning instrument, and storing the position information into a database; calculating the total row number of photovoltaic panels in the photovoltaic module according to the collected position information of the photovoltaic module; controlling the flight of the unmanned aerial vehicle, and correcting the flight path of the unmanned aerial vehicle by using the position information of the four corner points of the photovoltaic module in the flight process; identifying and segmenting a single photovoltaic panel in an aerial image by using an image algorithm, and positioning the column number of the photovoltaic panels in the photovoltaic module; and performing judgement through a signal receiving device on the unmanned aerial vehicle so as to start an infrared camera, and detecting hot spots in real time, and processing the hot spots to obtain the position information of the hot spots. According to the method, automatic inspection of the unmanned aerial vehicle is fully utilized, automatic positioning of the hot spots is achieved, correction of the flight path of the unmanned aerial vehicle is achieved, calculation is convenient, the detection efficiency is high, and a photovoltaic power station can operate more efficiently and intelligently.

Problems solved by technology

At present, the more popular solution is to use drones to shoot, send back the video, and then manually calibrate the hot spot position. Because people have certain visual errors, it is easy to calibrate wrongly, and it also wastes human resources.
