A transputer‐based system has been developed for the measurement of dynamic displacements in real time by visually tracking moving objects from a video Input. Parallel processing techniques have been used to track multiple objects at frame rate, and various predictive tracking algorithms have been assessed and implemented on the transputer network. The system is primarily intended for applications such as the monitoring or testing of large physical structures where actual displacements may not easily be otherwise determined. Results from the monitoring of the behaviour of the Humber Bridge at the centre of its span are presented.
