摘　　要：随着海洋探索技术的不断进步,基于多波束声呐技术应用的海底地形三维模型可视化建模已经成为海洋科学研究的重要工具。为此,提出了一种综合方法,该方法利用多波束声呐系统采集的海底地形数据,通过数据预处理、格网化、三维建模、纹理映射及可视化等步骤,实现海底地形的精确三维表示。实验结果表明,该技术不仅提高了海底地形数据的可用性和可解释性,而且通过高效的数据处理算法,增强了模型的分辨率和细节表现。水平分辨率和垂直分辨率分别高达2 m和0.5 m,为海洋地质、生态、考古及工程应用提供了强有力的支持。With the continuous progress of ocean exploration technology,the visualization modeling of seabed terrain 3D models based onApplication of multi-beam sonar technology has become an important tool for marine scientific research.This study proposes a comprehensive method that utilizes seabed terrain data collected by a multi beam sonar system to achieve accurate 3D representation of seabed terrain through data preprocessing,gridding,3D modeling,texture mapping,and visualization.The experimental results show that this technology not only improves the availability and interpretability of seabed terrain data,but also enhances the resolution and detail representation of the model through efficient data processing algorithms.The horizontal resolution and vertical resolution are as high as 2m and 0.5m,respectively,providing strong support for marine geology,ecology,archaeology,and engineering applications.
