Electric Power Tower Inclination Angle Detection Method Based on SIFT Feature Matching

摘要

In video monitoring system of substation, in-process video inspection is used to detect abnormalities and provide corresponding solutions in a timely manner to avoid failures.As the common equipment, electric power tower's inclination should be detected timely..It was hard to check the fault of tower inclination timely and accurately only by staff's routine inspection, and it will spent much manpower and material resources by the manner of sensor. A manner of substation video inspection tower inclination angle detection based on SIFT feature matching and OTSU was presented in this paper. The tower inclination angle was calculated through the matched feature points. As is proved in the simulation test, this algorithm features simplicity and it can detect the maximum angle in all case of inclination.
