Abstract
<p> 3d-LiDAR enable to get wide range point cloud data without UAV. It is difficult to get water surface by using LiDAR that use near infrared rays. But can get a part of the surface like whitecap. If it becomes possible to measure water surface by using LiDAR, it can be used for wide range wave measurement and solid-liquid measurement such as wave and sand on the coast. Therefore, in this study we examined the applicability of water surface measurement using 3d-LiDAR by water tank experiment.</p><p> As a result of regular wave experiment, it became clear that LiDAR provide water surface data right under them. Measurement accuracy of LiDAR is affected the number of point cloud data and by increasing integral time within one-fifth of the wave period, accuracy is improved. In addition, we developed a method that get point cloud data indirectly by projecting a laser reflected on the water surface onto the screen.</p>
