Embodiment Construction

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

[0026] UAV photovoltaic inspection is to use the UAV to mount the corresponding load equipment, detect the abnormal component unit in the photovoltaic scene through low-altitude flight, and feed back the specific location of the unit to the staff as the basis for subsequent repair processing. Infrared cameras perform well in detecting abnormal targets such as hot spots, zero current, and fragmentation, and are usually used as a must-have payload. However, when using the target positioning based on the tracking algorithm, the low resolution of the infrared camera and the color difference of the image cannot provide a stable basis for feature matching. At this time, the visible light image can be used to make up for the missing information. Therefore, the process of inspection needs to be mounted and can be collected at the same t...

Abstract

The invention discloses a method for locating an inspection target of an unmanned aerial vehicle in a flat single-axis photovoltaic scene. This method divides the component units of each frame of infrared images collected by patrol inspection, and combines the tracking relationship between visible light images to finally realize the positioning function of abnormal component units in the infrared image in the global map. The invention not only solves the problem of difficult positioning of abnormal component units in a flat single-axis scene, but also establishes a mapping relationship between component units and global logic numbers, thereby improving the feasibility and operating efficiency of unmanned aerial vehicle photovoltaic inspections.

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 flat single-axis photovoltaic scene. Background technique [0002] The demand for electricity in various industries is also becoming stronger and stronger, but the traditional power generation method has brought a series of negative problems to energy and the environment. Clean energy has attracted more and more attention. Among them, photovoltaic power stations are the most important clean energy. It has attracted worldwide attention. As of the first half of 2019, my country has achieved a cumulative installed capacity of 200GW. The UAV system uses modern technology and has the characteristics of low cost, simple maintenance and easy operation. These characteristics make UAVs very suitable for monitoring and maintenance of photovoltaic power plants. UAV inspection can not o...
