The multibeam bathymetry model is constructed based on the optimization of the survey line

Multi beam bathymetry is a water depth measurement technology developed based on single beam bathymetry, utilizing the propagation characteristics of sound waves. Its coverage range is wider than that of single beam bathymetry. In order to improve the measurement efficiency of multi beam bathymetric vessels and obtain survey line optimization schemes suitable for different sea conditions, a specific sea area model was established. Firstly, a spatial coordinate system was established to calculate the transformation model of the equivalent slope spatial slope problem, and data with good regularity was obtained. Through this method, the linear variation pattern of the slope surface was discovered, and a linear model of the measuring line was established. In addition, by analyzing the impact of boundary depth changes caused by slopes on coverage, constraints for optimizing coverage and path length were established, and the optimal solution scheme for the survey line was obtained. By applying this solution, depth vessels can more accurately obtain seabed terrain data and improve measurement efficiency. This study has broad application prospects and important practical value in different types of seabed topography.
