Method for monitoring periphery displacement of construction field through total station instrument carried by unmanned aerial vehicle

Abstract

The invention discloses a method for monitoring periphery displacement of a construction field through a total station instrument carried by an unmanned aerial vehicle. According to the method, displacement variations of the periphery of a subway construction site are monitored through an unmanned aerial vehicle, a damping cloud deck, a total station instrument and a database, testing points and reference points have the characteristics of being scientific and reasonable to set up, convenient in monitoring, accurate in data and high in efficiency, the monitoring process can be automatically carried out, a great amount of human sources can be saved, the instrument transferring process in complex regions of cities is reduced, the monitoring efficiency and precision can be improved, and scientific bases can be made for construction of subways and other underground buildings.

Description

technical field [0001] The invention belongs to the technical field of subway engineering construction monitoring, in particular to a method for monitoring the displacement around a construction site by carrying a total station on an unmanned aerial vehicle. Background technique [0002] During the construction of the subway project, it will have a certain deformation, and it will also have a certain impact on the surrounding environment. In order to ensure the safe construction of the subway project, it is necessary to monitor the displacement of the subway project and the surrounding environment. [0003] At present, the displacement of the surrounding environment of the subway is mainly monitored by a level or a total station. The subway construction is mainly located in the core area of ​​the city. There are a large number of buildings around the site, and the construction site is narrow and the surrounding conditions are complex. There is no good visibility, so the meas...

AI Technical Summary

Problems solved by technology

The subway construction is mainly located in the core area of ​​the city. There are a large number of buildings around the site, and the construction site is narrow and the surrounding conditions are complex. There is no good visibility condition, so the measuring instruments need to transfer stations many times to complete the monitoring, which will lead to excessive monitoring of the route. Long and affect the measurement accuracy, and at the same time lead to low measurement efficiency

[0004] There is also an image method used to calculate the displacement of the target point by comparing the images before and after, but this method has low monitoring accuracy and cannot meet the requirements of on-site construction

[0005] The method of monitoring the displacement around the construction site through a drone equipped with a total station has not yet been reported.
