In this embodiment, the dirty image in 2 surfaces of controller through discernment radar obtains dirty distribution state, and the controller can only clean the dirty place in 2 surfaces of radar, has increased unmanned aerial vehicle's automatically cleaning efficiency.
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
