Abstract
The present application relates to the technical field of image processing, and discloses a power transmission line tree barrier identification and early warning method and system, the power transmission line tree barrier identification and early warning method comprises the following steps: step S101, obtaining local direction and local width; step S102, obtaining a detrended signal; step S103, obtaining an axial spectral kurtosis peak value; step S104, obtaining a conductor main path; step S105, classifying and marking the line element; step S106, triggering an early warning when less than the safety radius. The present application is based on the normalized frequency domain analysis and spectral kurtosis peak value extraction of stranded conductor physical pitch, which strengthens the recognition of conductor quasi-periodic characteristics, and combines with the local direction constraint path search to locate the conductor main path; the adaptive threshold classification and dynamic safety radius setting can adapt to different imaging conditions and conductor sizes without manual parameter adjustment, which greatly reduces the false alarm and missed alarm probability; thereby providing protection for the safe and stable operation of the power transmission line.
