Abstract

The invention discloses a forest fire predication method and system based on a power transmission line forest fire image. According to a power transmission line forest fire gray level image, forest fire images subjected to edge extraction are obtained. According to the forest fire image subjected to edge extraction and the forest fire location, the forest fire is classified and the gray level image subjected to forest fire classification is obtained. According to the gray level image subjected to forest fire classification and the current forest fire geographic information, the forest fire spreading range is predicated. According to the invention, through noise reduction treatment of the power transmission line forest fire gray level image, image precision is improved; and then forest fire classification is performed and the forest fire spreading range is predicted through combining with the specific information of the forest fire location, so that the predication result becomes more accurate.

Description

technical field [0001] The invention relates to the technical field of transmission line mountain fire image processing, in particular to a method and system for mountain fire prediction based on transmission line mountain fire images. Background technique [0002] In recent years, as the country's policy of "returning farmland to forests" has become stronger and stronger, barren mountains and wastelands have gradually been covered by dense vegetation, and the vegetation near power transmission lines has also become denser. Extreme weather can easily trigger large-scale wildfires, which not only threaten the ecological environment and the safety of human life and property in the area affected by the fire. At the same time, wildfires near the transmission line will cause the transmission line to trip, seriously affecting the safe and stable operation of my country's power grid. [0003] At present, the data research of digital images of mountain fire disasters on transmissio...
