Tóm tắt

Monitoring the displacement of high-rise buildings using a terrestrial laser scanner (TLS) is an active research topic in the field of engineering surveying. The Faro Focus3D X130 is one of the most suitable scanners which is widely used in different industries, such as architecture, archaeology, shipbuilding, and construction. However, in engineering surveying, the potential use of this scanner is not investigated for displacement monitoring yet. This paper's goal is to evaluate the accuracy of this scanner in the displacement monitoring of high-rise buildings. In the fieldwork experiment, the high-rise-rise building’s displacement is simulated by a movement of the board installed on this building. In addition, the surface material, scanning geometry, and point density of data that influenced the scan quality are investigated. The cloud - to - cloud method in CloudCompare software is applied to measure the distance between point clouds in two epochs. The distance between two point clouds allows determining the displacement of the board in two epochs. The results show the deviation between displacement analyzed from point clouds and the actual displacement is smaller than 2 mm in all experiments. TLS completely fulfills the required accuracy in the displacement monitoring according to the Vietnam construction standard. This study indicates that Faro Focus3D X130 is suitable to use in the displacement monitoring of high-rise buildings in practical engineering surveying.
