| Outline of Final Research Achievements |
A novel imaging system to measure three-dimensional surface shapes, based on the projector-camera system, was improved with aim to extend the practical applicability to coastal and hydraulic engineering. The additional algorisms to synchronize the projector and digital camera and to dynamically track the color patterns reflected on the surfaces were developed and introduced to the measurement system. The additional improvement for reducing optical errors associated with Lambert multiple dispersion system formed in liquid was also introduced to the system.
The developed measurement system was applied to experimental breaking waves to examine the reliability and capability to measure dynamic deformation of the free-surface. The measured results provided new aspects of the physical evaluation of transient free-surface forms of breaking waves.
