The invention provides a Lambert power estimation method based on an unmanned aerial vehicle landing-assisting ultraviolet LED. In the landing process, a ground platform places LED array ultraviolet light at uniform intervals according to a certain rule based on a signal transmitter to provide a guide signal for an unmanned aerial vehicle; and when the unmanned aerial vehicle approaches an autonomous landing platform, a receiver carried on the unmanned aerial vehicle starts to detect a ground ultraviolet light signal, the ultraviolet light signal is detected when the unmanned aerial vehicle ish1 away from the ground, and ultraviolet light information is obtained through decoding to determine that the place is a target launching platform of the unmanned aerial vehicle. The divergence of the LED light source is studied by analyzing the Lambert characteristics of the ultraviolet LED, so that more accurate information can be provided for flight guidance of the unmanned aerial vehicle whenthe ultraviolet LED serves as a guidance light source, the landing reliability of the unmanned aerial vehicle is improved. The method is reasonable in design, capable of achieving accurate landing under different conditions and wide in applicability.
本发明提出了一种基于无人机助降紫外LED朗伯功率估算方法,在降落过程中地面平台根据信号发送机按照一定规则放置间隔均匀的LED阵列紫外光为无人机提供引导信号;无人机接近自主着陆平台时,搭载在无人机上的接收机开始探测地面紫外光信号,无人机距离地面h1时探测到紫外光信号,通过译码获取紫外光信息确定此处为无人机目的投放平台。通过分析紫外LED的朗伯特性研究LED光源的发散性,使得紫外LED作为引导光源时可以为无人机飞行引导提供更为准确地信息,从而提高无人机降落的可靠性,该方法设计合理,能够在不同情况下实现准确降落,适用性广泛。
