Application of Image Processing in Patrol Inspection of Overhead Transmission Line by Helicopter

Due to its features such as high efficiency,accuracy and safety,patrol inspection by helicopter evolves as an important inspection manner for high voltage overhead transmission lines.Through the processing and analysis on lots of aerial photographs acquired by patrol inspection with helicopter,the faults and defects of transmission lines can be found,so there is a good application prospect of image processing technology in patrol inspection of overhead transmission lines.Present research situation of applying image processing to patrol inspection of overhead transmission lines by helicopters home and abroad is analyzed,and main technical problems to be solved in the field of applying image processing technology to this field are put forward,and possible solutions are discussed.Finally,the development trend in this field is prospected.
