The invention discloses a
system and method for measuring the image distance of a
power transmission line through an unmanned aerial vehicle, wherein the
system comprises the unmanned aerial vehicle,a main console and a plurality of cameras, and the plurality of cameras are fixed on a power pole
tower and are used for collecting the two-dimensional image data of a corridor of the
power transmission line. The unmanned aerial vehicle comprises a vehicle body, a
laser radar device, a rotor wing
assembly, a power device, a flight control processor, a state detection device and a
wireless communication module; the
laser radar device is used for collecting three-dimensional
point cloud data of the
power transmission line, and the main console is used for receiving the two-dimensional image dataand three-dimensional
point cloud data; a mapping relationship between the two-dimensional image data and the three-dimensional
point cloud data is established; a target object is identified according to the two-dimensional image data, three-dimensional point coordinates of the target object are determined according to the mapping relationship, and the distance from the target object to the powertransmission line is calculated according to the three-dimensional point coordinates of the target object; and the target
object distance condition of the whole power
transmission line corridor can be monitored through the cameras, and all-weather and all-time power
transmission line monitoring is achieved.
