摘要
为获取某海岛停泊水域、回旋水域水下地形情况,采用SeaBat T20-P多波束测深系统结合POS MV SURFMASTER惯性导航系统进行扫海测量,获取了停泊水域、回旋水域1∶500水底三维模型图。对多波束测量精度进行内、外符合检查,结果表明,精度符合规范要求。通过对水下地形情况进行定性分析,获得了测区停泊水域、回旋水域的准确高程值。实验表明:采用SeaBat T20-P多波束测深系统可实现高精度水下三维地形的获取,本文的研究结果可为相关工程应用提供参考。
In order to obtain the underwater topography of the mooring waters of an island,the SeaBat T20-P multi-beam sounding system combined with the POS MV SURFMASTER inertial navigation system was used for sea sweeping surveys,and the 1∶500 scale bottom three-dimensional model of the mooring waters was obtained.The multi-beam measurement accuracy was inspected internally and externally,and the results showed that the accuracy met the specification requirements.Through the qualitative analysis of the underwater terrain,the accurate elevation values of the mooring water area and the turning water area of the survey area are obtained.Experiments show that the SeaBat T20-P multi-beam sounding system can achieve high-accuracy underwater three-dimensional terrain acquisition.The research results in this article provide references for related engineering applications.
