Embodiment 1

[0045] Such as figure 1 As shown, a kind of crown multi-threshold segmentation method embodiment that can be used in transmission line tree height monitoring device of the present invention comprises the following steps:

[0046] Step 1: Obtain the photos of trees and bamboos in the transmission channel taken by the tree height monitoring device of the transmission line, and upload them to the back-end control center, such as figure 2 , Figure 6 shown;

[0047] Step 2: After receiving the photos, the back-end control center extracts the canopy targets in multiple visible light tree and bamboo photos;

[0048] First, the visible light tree and bamboo photos are transformed from the RGB color space to the HSV color space. Set the RGB color space value (r, g, b), r, g, b∈[0,1,...,255]. Among them, r, g, and b represent the values ​​of red, green, and blue in the RGB color space, respectively.

[0049] By analyzing the characteristics of a large number of canopy photos in R...

Abstract

The invention discloses a crown multi-threshold segmentation method and system for a power transmission line tree height monitoring device. According to the method, automatic analyzing of a tree and bamboo monitoring image returned by the power transmission line tree height monitoring device is realized; multi-threshold segmentation of RGB color space and HSV color space is carried out on the crown; accurate extraction of tree tips or branches in the crown is realized based on a Harris corner monitoring algorithm; and a foundation is laid for calculation of the distance from the crown to a wire and safety risk assessment of trees and bamboos to a power grid. According to the invention, automatic extraction of the tree tips or branches in the crown is achieved; and automatic monitoring of the tree height in a power transmission channel is achieved. According to the method, calculation of the distance between the crown height and the wire can be further achieved. The method and system, which are provided by the invention, are simple in principle and high in practicability, can be used for the online monitoring device of the power transmission line channel and have a wide applicationprospect.

Description

technical field [0001] The invention relates to the technical field of power grid protection, in particular to a tree crown multi-threshold segmentation method and system that can be used in a power transmission line tree height monitoring device. Background technique [0002] When the tree and bamboo superelevation in the transmission channel is too close to the wire, it may cause the transmission line to discharge to the tree and bamboo and cause a short circuit fault. As the scale of the power grid continues to expand, more and more transmission lines cross forest land, and trees and bamboos pose an increasing threat to the safe and stable operation of the power grid. In order to deal with the hidden dangers of trees and bamboos, power grid enterprises mainly rely on manual inspection to find super-high trees and bamboos, and cut down super-high trees and bamboos in time. There are also some image and video online monitoring devices applied to the monitoring of power tra...
