Prefabricated building construction monitoring method based on unmanned aerial vehicle technology

Abstract

The invention relates to a fabricated building construction process monitoring method based on an unmanned aerial vehicle, and the method comprises the steps: S1, generating a building simulation model according to a construction drawing, the building simulation model being composed of a plurality of building components; s2, an unmanned aerial vehicle is used for collecting building component images in the construction process; s3, generating a twin entity model and a twin line model according to the building construction component image; the twin entity model is composed of the cross section of a building component, and the twin line model is composed of the axis of the building component; and S4, comparing the twin line model and the twin entity model with the building simulation model, and carrying out construction progress monitoring and construction quality monitoring. According to the monitoring method, the unmanned aerial vehicle is used for collecting the images of the building components, manpower does not need to be consumed for collection at multiple positions of a construction site, numerous RFID tags do not need to be attached to each component, and the monitoring method has remarkable manpower and economic cost advantages.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a method for monitoring the construction process of a prefabricated building based on unmanned aerial vehicle technology. Background technique [0002] Prefabricated buildings have the characteristics of standardized design, factory production, assembly construction, and information management.

Problems solved by technology

At present, the commonly used construction progress monitoring methods mainly include: First, human monitoring, manual collection with the help of total stations, levels, etc., the amount of work is large and has certain local limitations, the data lags seriously, and the measurement results are somewhat subjective The second is RFID collection, which is to collect construction progress information through radio frequency identification, but this method requires buildings and each component to be attached with enough RFID tags, which is costly and complex, and the density of collected data varies. , time lag

Prefabricated buildings require high construction accuracy and fast construction speed, so higher requirements are put forward for the monitoring of construction progress. Traditional construction progress monitoring methods have been unable to effectively utilize the technical advantages of prefabricated buildings, hindering the development of prefabricated buildings.
