Visual Simulation of Seafloor Topography Based on Biharmonic Interpolation

摘要

摘要: 由于电子海图中只包含海洋环境的矢量数据, 并未给出海底地形相关信息。本文利用ISO8211类库, 提取S-57电子海图原始文件的矢量水深数据, 依据这一组水深数据进行Biharmonic曲面样条插值, 计算出一组曲面上的网格点处的坐标数据, 从而实现对该海区内海底地形的可视化仿真。同时利用插值后的坐标数据, 进行等深线绘制仿真, 将仿真结果与专业电子海图软件打开同一张海图进行对比以及误差分析, 结果表明, 使用插值数据构建地形的正确性, 规则分布的插值水深数据可用于自主式水下航行器(AUV)的自主路径规划。

Abstract: The electronic chart only includes the vector data of marine environment, however it doesn′t give seafloor topography information. We extract the depth vector data from S-57 original document by using the ISO8211 library, calculate a set of grid points data based on the water depth data by Biharmonic curved surface spline interpolation, so as to visually simulate underwater terrain. The interpolated data are used to simulate depth contour, and the result shows consistency with that of the special electronic chart software. Error analysis demonstrates the validity of the proposed method in constructing seafloor topography. Regularly distributed interpolated data can be used for path planning of an autonomous underwater vehicle.
