Large-scale centralized photovoltaic power station image data acquisition method based on multi-rotor unmanned aerial vehicle (UAV)

Abstract

The invention relates to a large-scale centralized photovoltaic power station image data acquisition method based on a multi-rotor unmanned aerial vehicle (UAV). A UAV can process visible light videostream information by carrying a processor; after the UAV is lifted off, the position and arrangement direction of photovoltaic module strings in the field of view can be calculated in combination with the own state information of the UAV, and the UAV can realize the automatic tracking of the photovoltaic module strings according to the calculation result; by calculating a flight distance, the UAVcan automatically collect visible light images and infrared image data; when the UAV reaches the regional boundary, a steering strategy is automatically executed; and by repeating the above process,the UAV can realize an image data collection task for the entire centralized photovoltaic power station, and can be further used for fault detection. Compared with other UAV-based data acquisition methods, the method of the invention is simple and efficient to implement, does not depend on the position information of photovoltaic modules, only needs to obtain regional information of the photovoltaic power station, and has strong environmental adaptability.

Description

technical field [0001] The invention relates to the application development of unmanned aerial vehicles and the inspection of large-scale centralized photovoltaic power plants, and in particular to a method for collecting image data of large-scale centralized photovoltaic power plants based on multi-rotor unmanned aerial vehicles. Background technique [0002] The drone industry has ushered in a blowout development all over the world. In recent years, the growth rate of consumer drones in the Chinese market has remained above 50%. Chinese drone companies represented by DJI have dominated the world. More than 70% of the consumer drone market. The "Guiding Opinions on Promoting and Regulating the Development of the Civil UAV Manufacturing Industry" issued by the Ministry of Industry and Information Technology clearly states that the civilian UAV industry will continue to develop rapidly, with an output value of 60 billion yuan in 2020 and an average annual growth rate of more ...

Problems solved by technology

[0005] However, at present, the inspection of photovoltaic power plants is still dominated by manual inspection, which is extremely inefficient, and because the installation environment of centralized photovoltaic power stations is relatively complex, manual inspection is difficult to meet the requirements in most scenarios
