Abstract: With the high-speed development of unmanned aerial vehicle in power line detection, acquiring the power line in aerial images has become the foundation of the detection research. And how to catch the completed power line in complex background has been the focus in power line research field, which can’t wait to solve. Thus the thesis puts forward a line-recovering method based on features, which can manage to connect the fragmented power line according to their geometry features after the arithmetic and transform. The experimental result shows it can track the intact power line, which has an accurate position. Except that, the thesis has the advantages of simplicity and stabilization and makes great effect on power line detection.
