Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The present invention is based on the method for measuring the inclination of transmission line towers based on video difference, such as figure 1 As shown, the specific steps are as follows:

[0027] Step 1: Obtain the tower image through a fixed-focus camera with a pan-tilt installed on the site iron tower or iron pole;

[0028] Step 2: Preprocessing the resulting tower image to obtain an image that is convenient for post-processing;

[0029] The preprocessing is carried out according to the following steps:

[0030] a. Perform grayscale processing on the acquired tower image. In view of the structural characteristics of the tower and the convenience of image processing in the future, refine the edges in the grayscale image. The main purpose is to refine the edges of the tower.

[0031] b. Since the grayscale distribution of the t...

Abstract

The invention discloses a method for measuring power transmission line pole and tower inclination based on video differences, comprising the following steps: acquiring a pole and tower image through a fixed-focus camera, pretreating the pole and tower image to obtain data of the pretreated image, and calculating an angle of inclination of the power transmission line pole and tower according to the data of the pretreated image. According to the invention, the angle of inclination of the power transmission line pole and tower is acquired only by image processing and simple calculation without establishing accurate mathematical models, and the enforcement is simple; global data of the angles of inclination of the whole power transmission line poles and towers can be acquired by programming to centralized processing images and carry out relative calculation in a remote monitoring center, thus the invention is beneficial for realizing the automatic security monitoring, so that the invention has important social significance.

Description

technical field [0001] The invention belongs to the technical field of machine vision and electric power system online monitoring, and relates to a method for measuring the inclination of a power transmission line tower, in particular to a method for measuring the inclination of a power transmission line tower based on video difference. Background technique [0002] With the distribution of power grids becoming wider and wider, the ground conditions and environments faced by transmission towers are becoming more and more complex, and the requirements for their safety are getting higher and higher. It is necessary to study the state detection system of towers. In order to be able to monitor the inclination angle of towers in unfavorable geological areas such as debris flow and landslide-prone areas, coal mine goafs, etc., the researchers designed an inclination sensor installed in an anti-interference shielding box, and then through a wireless transmission unit, let the inclin...
