Helicopter power line inspection method

The present invention discloses a power line inspection method of the unmanned helicopter, comprising: a power line tower segment in accordance with, and laying the track unmanned helicopter transmission line to the power line of the segment; without the need of people in various helicopter tower at hover, each track intersections transmission line segments will track hovers as point; degree of overlap in accordance with requirements of the camera on the transmission line path and the helicopter, when calculating camera unmanned helicopter patrol exposure point coordinates; stable computing platform on unmanned helicopter according to the azimuth and elevation coordinates of the camera exposure; power line for inspection. According to the present invention can be quickly and reasonably complete unmanned helicopter patrol preparations for different inspection tasks unmanned helicopter to ensure safe, reliable flight, each sensor can be efficiently acquire the device data transmission line during the transmission line bring to power line inspection work unmanned helicopter great convenience.
