| Research Abstract |
Reflected Light Distribution method (RLD method) is a method for 3-D wave field measurements by using reflected light image from diffused light source. The unique feature of this method is that it allows free surface mapping by single camera without seeding materials on the water surface. In this study, we developed two techniques for extending dynamic range of the RLD method. The first is wave height reconstruction technique by using iterative calculation. The second is new tracking method for large deformed reflected light images.
