Abstract

A visual tracking system has been employed in the measurement of deck displacements at the centre of the 1410 m span of the Humber Bridge in the UK. The transputer-based system was developed for applications such as the monitoring or testing of large physical structures, where the actual displacements may not easily be otherwise determined. The system employs parallel processing techniques to track predictively the motion of multiple, independent objects at video frame rate. Results obtained using the system in a monitoring programme of the bridge are presented and discussed.
