3D bathymetry measurements in shallow-water environments with a low-cost sensor – study published

To take bathymetric measurements in areas with shallow water is very challenging for methods such as SONAR or bathymetric LiDAR. In our study “Assessing the Potential of a Low-Cost 3-D Sensor in Shallow-Water Bathymetry”, we examine the performance of a low-cost 3D camera when capturing bathymetry in waters up to 0.4 m depth.

The tested measurement setup provides 3D datasets with an accuracy and precision comparable to high-end approaches, and the maximum measurement range through water was found to be 0.3 m in outdoor conditions and 0.4 m in indoor conditions. Furthermore, a wave mitigation setup including a refraction correction procedure is introduced. Overall, the proposed measurement and processing setup offers a powerful complementary tool for research on 3D bathymetry in shallow waters.
