摘要
海洋地质调查中获取大量海洋沉积物柱状样样品测试分析数据,样品测试分析目的不同导致柱状样数据采样深度不同,由此造成地质取样数据在三维空间上呈现不规则散点状分布。传统聚类算法无法在三维空间上对此类不规则散点数据进行聚类分析。对此,文章设计了一种基于空间插值的不规则地质样品测试分析数据聚类算法,有效地将三维样品测试分析散点数据降为二维数据后进行聚类分析,本算法较好地解决了地质体中试验测试数据的不均衡性问题,为海洋地质大数据分析提供了基础技术方法。
A large number of core sampling data were obtained from marine geological survey.Different kinds of measurement data have different sampling depths,resulting in irregularly scattered distribution of 3D geological sampling.The irregularly scattered data on the three dimensional were not able being clustered using traditional clustering algorithm especially in the case of big data analysis.The present study designs a clustering algorithm for irregular geological sampling data based on spatial interpolation.In this way,the 3D geological scatter data can be effectively reduced to 2D data,and the computational complexity can be reduced.This algorithm can better solve the classification and analysis of inequality measurement data in geological bodies,and provides a basic technical method for marine geological big data analysis.
