Abstract

Through the long-term and precise structural deformation monitoring of buildings to determine its health status is very important for their safe use and operation maintenance. At present, the traditional surveying measurement is mainly used to monitor the building deformation, which is not only labor-consuming and time-consuming, but also for some parts of the building that are not easy to reach, the observation becomes very difficult or even impossible to achieve. This paper compares and analyzes the advantages and disadvantages of several surveying technologies, including traditional measurement and the latest digital methods, e.g. 3D laser scanning technology, GNSS (Global Navigation Satellite System) technology, and digital close-range photogrammetry technology, in their application of structural deformation monitoring. The key technology and main steps of digital close-range photogrammetry in deformation monitoring is focused here. Unlike traditional surveying methods which are limited to discrete point monitoring, digital close-range photogrammetry can non-contactly obtain complete images of the monitored object at different times and spatial coordinates of the monitoring points, thereby obtaining comprehensive deformation data of the building. The additional stress variation law of the building can be quickly and accurately determined, which is beneficial to establishing a more detailed prediction system for building deformation. The example of digital close-range photogrammetry in structural deformation monitoring is carried out to demonstrate the improved algorithm. The result shows that the accuracy can reach millimeter level, which means it is comparable to traditional high-precision surveying methods, e.g. the total station measurement.
