Summary
This paper presents the evaluation of the deformation monitoring of bridge structures with a profile scanner and shows that existing monitoring concepts can be extended with the use of profile scanning.
The contact-free acquisition method of a profile laser scanner 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.
