摘要
随着大数据、云计算、5G技术的发展成熟,电力供电系统除了对输配网系统有着明确的可靠性要求外,也对电力巡检系统提出了更高的自动化和智能化要求。利用无人机进行输电线路巡检具有安全性高、工作效率高和精准拍照、分析等优点,在电力巡检领域应用越来越广泛。文章提出了一种无人机电力巡检系统中的测温分析方法,对无人机拍摄回传的可见光图和原始红外图像进行分析,利用反射率和相机校准参数对温度信息进行校准。结果表明,该方法可以得到更加接近真实值的温度信息,提高无人机电力巡检中故障检测的准确率和效率。
With the development and maturity of big data,cloud computing and 5 Gtechnologies,the power supply system not only has clear reliability requirements for the transmission and distribution network system,but also puts forward higher automation and intelligence requirements for the power inspection system.UAVis widely used in the field of power transmission line inspection because of its advantages such as high safety,high efficiency,accurate photographing and analysis.In this paper,a temperature measurement and analysis method in UAV power patrol system is proposed.The visible light image and original infrared image taken by UAV are analyzed,and the temperature information is calibrated by using reflectivity and camera calibration parameters.The results show that this method can get the temperature information closer to the real value and could improve the accuracy and efficiency of fault detection in UAVpower patrol.
