The invention relates to the technical field of unmanned aerial vehicles, and provides an unmanned aerial vehicle flight noise interference reduction method and device and an unmanned aerial vehicle, and the method comprises the steps: firstly, when the unmanned aerial vehicle receives an inspection instruction, the unmanned aerial vehicle flies to a preset point location, and a noise signal is collected; and then carrying out routing inspection by using the routing inspection instruction, controlling the acoustic imaging assembly to collect a routing inspection signal, and carrying out noise removal on the routing inspection signal based on the noise signal. According to the method, noise signals are collected before routing inspection, noise removal is carried out on routing inspection signals collected in the routing inspection process under the condition that the noise signals are known, a hardware structure does not need to be transformed, and interference of noise on an acoustic imaging assembly is reduced under the condition that the load of an unmanned aerial vehicle is not increased. Moreover, the method for reducing the flight noise interference of the unmanned aerial vehicle can reduce the noise interference to a large extent, and guarantees the imaging effect of the acoustic imaging assembly.

    本发明涉及无人机技术领域,提供一种无人机飞行噪声干扰降低方法、装置及无人机,该方法首先在无人机接收到巡检指令时,飞行至预设点位,采集噪声信号;然后利用巡检指令进行巡检,并控制声成像组件采集巡检信号,基于噪声信号,对巡检信号进行噪声去除。该方法在巡检之前采集噪声信号,在噪声信号已知的情况下对巡检过程中采集的巡检信号进行噪声去除,不需要对硬件结构进行改造,在不增加无人机负载的情况下降低噪声对声成像组件产生的干扰。而且,该无人机飞行噪声干扰降低方法可以较大程度降低噪声干扰,保证声成像组件的成像效果。
