An image matching method and a monitoring system for power transmission passage external damage protection

Abstract

The invention provides an image matching method and a monitoring system for power transmission passage external damage protection. The system comprises a plurality of monitoring modules and a controlcenter. Each monitoring module includes a power module, an audible and visual alarm module, an image monitoring module, a main control system and a communication module. The image monitoring modules detect images of circuit channels on the two sides of iron towers and transmit the images to the main control systems; the main control systems perform hidden danger detection by using an image matching method based on Haar characteristic density maps, and, when detecting that hidden danger exists, inform the audible and visual alarm modules to give alarm. The Haar characteristic density maps are used for filtering, so that discrete pixel points of matching failure caused by small disturbances can be effectively removed; while it is guaranteed that block connected domains do not suffer loss themselves, discrete points therein and therearound can be batter maintained to match pixel images.

Description

technical field [0001] The invention relates to an image matching method and a monitoring system for external breakage protection of a power transmission channel. Background technique [0002] With the development of the national economy, the demand for electricity in all walks of life continues to expand, and the losses caused by power outages caused by various man-made and natural accidents are also increasing. How to detect, deal with and prevent natural disasters and accidents that endanger transmission lines early, and ensure the normal supply of power at all times, has become the focus of attention. [0003] At present, many places in our country have begun to monitor the line channel environment by installing image / video monitoring devices on the towers of various high-voltage transmission lines, replacing traditional manual inspection lines. The original image / video monitoring has a short lifespan, low reliability, and unintelligent hidden danger detection. The on-...

Problems solved by technology

However, because the transmission lines or channels are mostly set in complex field scenes, and the weather conditions are not good, the tower itself will shake to a certain extent, especially for large iron towers with higher voltage levels, the shaking range is greater, and the target in the background There will be shaking or dancing, and the weather, clouds and light will affect the effect of taking pictures. The affected images will not have a good effect on the protection of the power transmission channel.
