Method for detecting deformation of super high-rise building based on unmanned aerial vehicle oblique photography technology

Abstract

The invention discloses a method for detecting the deformation of a super high-rise building based on an unmanned aerial vehicle oblique photography technology. The method comprises the following steps: firstly obtaining image data through unmanned aerial vehicle oblique photography, carrying out the layout of image control points, check points and control points of the outer wall surface of the super high-rise building, measuring coordinates, and importing the image data and the coordinate data into modeling software to generate a live-action three-dimensional model; checking the control point position and check point recheck data on the live-action three-dimensional model to determine three-dimensional data; and finally, importing the three-dimensional data into three-dimensional detection software, reversely generating a new three-dimensional model, comparing the new three-dimensional model with the live-action three-dimensional model, and obtaining the deformation amount and the deformation track of the super high-rise building through calculation. The method makes up for the defects in the traditional monitoring technology, can obtain the relative comprehensive position information of the external facade of the building, and achieves the purpose of omnibearing deformation detection of the building.

Description

technical field [0001] The invention belongs to the technical field of oblique photography of unmanned aerial vehicles, and in particular relates to a method for detecting the deformation of super high-rise buildings based on the oblique photography technology of unmanned aerial vehicles. Background technique [0002] With the rapid development of China's economy, there are more and more super high-rise buildings in China. In the construction of super high-rise buildings, from construction to completion, it is necessary to continuously perform deformation detection on super high-rise buildings. In the current project, the deformation detection items of super high-rise buildings mainly include verticality detection, flatness detection, and settlement value detection. and offset detection etc. There will be deviations in the construction process of super high-rise buildings. The deviation is within a certain limit, which can be a normal phenomenon, but if it exceeds a certain...

AI Technical Summary

Problems solved by technology

[0004] The traditional building deformation detection method cannot observe the detailed structure, and the labor intensity is high, the efficiency is low, and there is a problem of large manual measurement error. The measurement method becomes very cumbersome, inconvenient, and the error is uncontrollable. For the verticality and flatness detection of the outer wall of a building exceeding a certain height, only feature point measurement can be performed, and it is basically impossible to achieve global monitoring.
