摘　　要：为实现海底地形的高分辨率呈现,准确还原海底地貌特征,提出了一种创新的侧扫声纳图像地形反演方法,该方法通过单波束测深数据的约束来实现海底地形的高分辨率重建。首先利用稀疏的单波束测深数据构建了初始海底地形模型,然后在海底反射模型的基础上,通过迭代优化算法,实现了高分辨率海底地形的反演。实验结果表明,该方法不仅显著提高了地形分辨率(提升60倍),而且确保了地形反演的高精度(误差小于15 cm)。这一研究成果不仅为海底地形的获取提供了新的思路,也为侧扫声纳技术的应用开辟了新领域。To achieve high-resolution representation and accurate reconstruction of seafloor topography,this paper proposes an innovative terrain inversion method for side-scan sonar images,which utilizes constraints from single-beam bathymetric data to realize high-resolution seabed terrain reconstruction.Initially,a preliminary seabed terrain model is constructed using sparse single-beam bathymetric data.Then,based on the seafloor reflection model,an iterative optimization algorithm is employed to achieve high-resolution seabed terrain inversion.Experimental results show that this method not only significantly enhances terrain resolution(by 60 times)but also ensures high accuracy in terrain inversion(with an error of less than 15 centimeters).This research not only provides a new approach for acquiring seafloor topography but also opens up new field for the application of side-scan sonar technology.
