The invention belongs to the technical field of the inspection of an unmanned aerial vehicle, and particularly relates to an intelligent inspection system with the unmanned aerial vehicle for a powerdistribution network. The intelligent inspection system comprises the unmanned aerial vehicle and a ground station, wherein the unmanned aerial vehicle comprises a remote sensing monitoring module which is used for completing the acquisition, storage, and transmission of inspection data; the remote sensing monitoring module comprises an image processor and an image recognizer which are connected to a camera in the remote sensing monitoring module; the image processor is used for treating the data of recognition images obtained by the camera, which comprises: step one. performing weighted average grayscale processing on the recognition images obtained in real time, and step three. performing filtering and noise reduction processing; the image recognizer is used for monitoring and judging the positions of the recognition images so as to judge the height and orientation of the unmanned aerial vehicle, which comprises: T1. obtaining the outlines of the recognition images based on the black-and-white images; T2. removing the contour of a non-regular polygon positioning area in the effective contour; and T3. removing the contour of a non-circular marking area in the effective contour. The intelligent inspection system improves the parking speed and inspection efficiency of the unmanned aerial vehicle on the basis that no additional detection and positioning device is needed on the body of the unmanned aerial vehicle.
