摘　　要：针对海洋底质的高精度几何划界问题,论文提出了一种基于采样数据内插的海洋底质高精度划界方法。首先,基于Delaunay三角形网连接采样点数据;然后,通过底质组分内插函数来进行空间定量划界,进而实现三角网内的底质划分;最后,对各类型底质进行合并,以实现海洋底质的高精度几何划界。实验结果表明:该方法能够基于采样点数据,求得目标点的底质类型,并为待求区域进行高精度划界。This paper proposes a high-precision boundary delineation method for ocean sediment based on sampled data inter⁃polation,aiming at the problem of high-precision geometric delineation of ocean sediment.Firstly,the sampled point data is con⁃nected by using Delaunay triangulation.Then,the spatial quantitative delineation is performed through the interpolation function of sediment composition,thereby achieving sediment partitioning within the triangulated mesh.Finally,different types of sediment are merged to achieve high-precision geometric delineation of ocean sediment.Experimental results demonstrate that the proposed meth⁃od can determine the sediment type of target points based on sampled data and achieve high-precision boundary delineation for the target region.
