Monitoring of supporting structures with profile laser scanning.
GeoPreVi 2018 International Symposium. Bukarest (29.10.-30.10.2018)
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
This paper presents the evaluation of measurements on bridge structures with a profile scanner and shows that existing concepts of classical monitoring measurements can be extended with the use of profile laser scanning.
The contact-free acquisition method of profile laser scanners reduces the expense for personnel and instrumentation compared to conventional sensors used for the monitoring of civil engineering structures. It furthermore enables the measurement of non-accessible areas of the monitored supporting structures. In addition, the availability of information along an entire structural profile can be used to flexibly deal with a wide variety of problems. With a measurement rate of at least 50 Hz, typical structural deformation signals can be recorded and sufficient data can be collected to characterize the underlying deformation processes dependably.
Overall, an automated and efficient spatio temporal processing scheme is presented, which is based on the discrete wavelet transform. With this signal analysis tool outliers are detected and eliminated, but furthermore an automated structural analysis based on the details of the supporting structures surface is realized. In addition to the derivation of deformations, a quality assessment with comprehensive integration of the redundant measurement information is possible as an in-situ uncertainty determination.
