Problems solved by technology

However, it can only measure the inclination rate of the tower itself, and cannot reflect the relationship between the tower and the surrounding geographical environment as a whole. In the actual application process, the surrounding environment of the tower is relatively complicated, and it may occur that the inclination of the tower does not reach the dangerous threshold, but the relationship between the tower and the surrounding geographical environment is relatively complicated. Danger is caused by the action of surrounding objects, so it is relatively single and one-sided to use only the slope rate of the tower as the judgment index, and cannot effectively and intuitively judge the danger of the tower

Embodiment 1

[0057] Such as Figure 1 to Figure 3 An embodiment of a method for quickly determining the danger of a power pole, comprising the following steps:

[0058] S1: Acquire the image data of the surrounding environment of the tower, establish a reference coordinate system, establish a three-dimensional real scene model of the tower, and import it into the GIS (Geographic Information System) platform;

[0059] S2: Based on the reference coordinate system, obtain the 3D point cloud data of the tower through laser scanning, establish the 3D point cloud model of the tower, and import it into the GIS (Geographic Information System) platform;

[0060] S3: According to the known design files of the tower, establish a three-dimensional reference model of the tower, and import it into the GIS (Geographic Information System) platform;

[0061] S4: The GIS (Geographic Information System) platform integrates and displays the imported model, and calculates the measured value of the tower's ris...

Embodiment 2

[0099] Such as Figure 4 Shown is a system for quickly judging the danger of power towers, including a GIS platform and a real scene building module connected electrically to the GIS platform, a point cloud scanning module, and a reference model conversion module. The real scene building module establishes a three-dimensional real scene model of the tower and It is imported into the GIS platform for display. The point cloud scanning module draws the point cloud data of the tower and imports it into the GIS platform for fusion display with the 3D real scene model. The reference model conversion module converts the design data of the tower into a 3D reference model and imports it In the GIS platform, the GIS platform calculates the measured value of the tower deformation by comparing the point cloud data with the 3D reference model, and judges whether it exceeds the threshold.

Abstract

The invention relates to the technical field of power transmission line maintenance, in particular to a method and system for quickly judging the dangerousness of a power tower, and the method comprises the following steps: S1, obtaining image data of the surrounding environment of the tower, building a reference coordinate system, building a three-dimensional live-action model of the tower, and importing the three-dimensional live-action model into a GIS platform; S2, taking the reference coordinate system as a benchmark, obtaining tower three-dimensional point cloud data through laser scanning, establishing a tower three-dimensional point cloud model, and importing the tower three-dimensional point cloud model into a GIS platform; S3, establishing a three-dimensional reference model of the tower, and importing the three-dimensional reference model into a GIS platform; S4, fusing and displaying the imported model by the GIS platform, and calculating to obtain a measurement value of the risk index of the tower; S5, enabling the GIS platform to judge whether the measured value is larger than a threshold value or not, if yes, sending out a danger prompt is sent out, and if not, returning a judgment result to the S4 to be displayed. The method enriches the judgment dimension of the risk of the tower, and is more intuitive and efficient.

Description

technical field [0001] The invention relates to the technical field of power transmission line maintenance, and more particularly relates to a method and system for quickly judging the danger of power poles and towers. Background technique [0002] During the construction and operation and maintenance of the line, the danger detection of the tower is a routine work. At present, methods such as traditional measurement of total station and drone inspection are commonly used, but traditional measurement requires a lot of manual work, and drone inspection is not sensitive to small deformations, and the detection results are not reliable enough. [0003] With the development and application of laser three-dimensional scanning in recent years, it presents the characteristics of lightweight hardware and functional integration. The industrial standard packaging model of GNSS-Rtk positioning integration, total station, automatic control, and multi-line array high-speed scanning weigh...
