Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and the specific implementation process.

[0026] The concrete implementation steps of described method are as follows:

[0027] Step S1:

[0028] UAV photovoltaic inspections are usually mounted with dual-light cameras with visible light and infrared. Infrared images are used to detect defect targets such as hot spots and zero current, but the resolution is low, such as figure 2 -b; Visible light images are used for auxiliary detection, and have the characteristics of large field of view, large distortion, and high resolution, such as figure 2 -a. Establishing the mapping relationship between dual-light images is the basis for subsequent work. An accurate mapping relationship not only facilitates subsequent image processing and can freely switch between dual-light images, but also helps in computational overhead and effect display. Step S1 mainly includes two part...

Abstract

The invention discloses a method for positioning an unmanned aerial vehicle inspection target in a fixed-axis photovoltaic scene. The method detects, locates, tracks, and maps the logical number of the smallest photovoltaic unit in the visible light image. On the basis of dual-light image registration, it realizes the defect target positioning in the UAV fixed-axis photovoltaic scene inspection. Function. The invention not only solves the problem of locating to the smallest unit, but also reduces the requirements for the positioning accuracy of the UAV and the pan / tilt during the image acquisition process, improves the operability of the UAV photovoltaic inspection and the staff's ability to locate defective plates Timeliness.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle inspection, and in particular relates to a method for locating an inspection target of an unmanned aerial vehicle in a fixed-axis photovoltaic scene. Background technique [0002] my country is the world's largest photovoltaic manufacturing country and the country with the largest installed capacity of photovoltaic power plants. As of the first half of 2019, my country's total installed capacity has exceeded 200GW. However, due to the wide distribution of photovoltaic power stations and various types of applications, the current operation mode has low efficiency, high error rate, long inspection cycle, and even the inability to achieve effective operation and maintenance, which has seriously restricted the healthy development of photovoltaic power stations. [0003] The emergence and rapid development of drones has become one of the effective means to solve the difficulties in the operation...
