The invention provides a pipeline defect detection method based on an unmanned aerial vehicle spectrum and an unmanned aerial vehicle, and belongs to the technical field of pipeline flaw detection, the method is applied to the unmanned aerial vehicle, the unmanned aerial vehicle is provided with a spectrum camera capable of relatively rotating, and the method comprises the following steps: utilizing the unmanned aerial vehicle to fly along with a pipeline to determine a pipeline section with a defect; the unmanned aerial vehicle is controlled to fly to the position over the pipeline section; temperature values T1 and T2 in the edge areas on the two sides of the pipeline section are extracted, the unmanned aerial vehicle is adjusted to move towards the side, where the larger value of T1 and T2 is located, of the pipeline section, and the temperature value delta T2 in the edge areas on the two sides of the pipeline section is determined at each adjusting position in the adjusting process; and when the delta T2 is not greater than the preset temperature difference value, collecting a target real image and a target hyperspectral image of the current pipeline section at the target adjustment position. According to the method, a worker can collect a complete defect form, the worker can conveniently find the specific position of the defect, a repair plan for the pipeline is formulated in advance, and the efficiency of repairing the pipeline is improved.

    本发明提供了一种基于无人机光谱的管道缺陷的检测方法及无人机,属于管道探伤检测技术领域,应用于无人机,无人机上设置有可相对转动的光谱摄像头,方法包括:利用无人机跟随管道飞行,确定存在缺陷的管道段,控制无人机飞行至管道段正上方;提取管道段两侧边缘区域内的温度数值T1、T2,调整无人机向T1、T2中较大数值所在的管道段一侧移动,并在调整过程中的每个调整位置,确定管道段两侧边缘区域内的温度数值ΔT2;在ΔT2不大于预设温度差值时,采集目标调整位置下当前管道段的目标真实图像和目标高光谱图像。可使工作人员采集到完整的缺陷形态,方便工作人员发现缺陷具体位置,并提前制定对于管道的修复计划,提高对管道进行修复的效率。
