Title: Application of a vision system to the monitoring of cable structures
Issue Date: 2007
Abstract: The current paper describes the development and implementation of a vision system in the context ofthe monitoring of a cable-stayed bridge, discussing the major requirements, the cost of theinstruments, the particular aspects of the developed image processing algorithms, the integration in aconventional monitoring system and the results of application to the International Guadiana Bridge inPortugal. This innovative system is shown to constitute a very useful complement to a conventionalmonitoring system whenever cable measurements are required, allowing not only for the identificationof the lower order natural frequencies of these elements, but also for the detection of the start-stop ofvibration events and corresponding conditions.
