This paper presents a new system for measuring breakzone locations, breaking wave height and wave periods across the surfzone from a digital video sequence. The system (Wave Pack) aims to provide real-time measurement of breaking and re-breaking wave heights and wave periods using low mounted video camera installations. Following on site data collection and analysis it was found that the Wave Pack...
A microprocessor-based CCD (charge-coupled device) image acquisition system has been developed with a resolution of up to 2048*2048 pixels. The system has onboard framestore, obeys a range of high-level commands, and is capable of maximizing image grey-scale dynamic range by optimizing exposure time and signal conversion parameters. The camera performance and functions are outlined.<<ETX>>
