Vision-Based Bridge Deformation Monitoring
Optics-based tracking of civil structures is not new, due to historical application in surveying, but automated applications capable of tracking at rates that capture dynamic effects are now a hot research topic in structural health monitoring. Recent innovations show promise of true non-contacting monitoring capability avoiding the need for physically attached sensor arrays. The paper reviews ...
متن کاملDeformation Monitoring of Bridge Structures by Ground-Based SAR Interferometry
In this paper, a ground-based SAR interferometry technology was used to monitor major engineering. This technology has been recognized as a powerful tool for terrain monitoring and structural change detecting. Deformation monitoring for large project has been a hot issue among them. According to GBSAR interferometry principle and characteristics of IBIS system, the authors analysis the error so...
متن کاملDeformation Monitoring of a Slope by Vision Metrology
This paper discusses monitoring of slope deformations by vision metrology with a CCD camera. Reflective targets are placed over a slope, and their object coordinates is measured by a photogrammetric technique. Precision and sensitivity of slope deformation measurement using vision metrology are investigated. Deformation of targets placed on a slope was detected by measurement at two time epochs...
متن کاملWhite Paper: Tiltmeter-Based Bridge Scour Monitoring
Scour is by far the primary cause of bridge failures in the United States. Scour and other hydraulic effects are particularly threatening because the deterioration is often invisible , hidden beneath turbid water. Many scour monitoring methods attempt to measure the development of scour pockets themselves. However, this is difficult due to debris — both floating and submerged — and shifting str...
متن کاملVision-based deep execution monitoring
Execution monitor of high-level robot actions can be effectively improved by visual monitoring the state of the world in terms of preconditions and postconditions that hold before and after the execution of an action. Furthermore a policy for searching where to look at, either for verifying the relations that specify the pre and postconditions or to refocus in case of a failure, can tremendousl...
