Intelligent Diagnostic Techniques of Abnormal Heat Defect in Transmission Lines Based on Unmanned Helicopter Infrared Video

摘要: An automatic electrical equipment abnormal heat diagnosis method using infrared image sequence adopted from unmanned helicopter(UHV) is proposed in this paper, which automatically identifies the locations of device fault for further manual inspection. Firstly, sequent frames are extracted video. Then, each frame stitched with its neighbors by conjugate features, and difference performed on to eliminate background. The principal direction power line calculated based non-background different frame. Finally, a model template matching schedule identify area. Finally intelligent location realized related national standards. Experimental studies validate effectivity robustness highly cluttered inspection scene.
