三维空间具某种属性的向量集群通常呈椭球状分布。用常规的方法提取这部分信息,要通过复杂的计算才能实现。本文推导出一种能快速提取三维信息的方法,称为三维向量筛。并介绍一个它在遥感图像中提取金矿化蚀变带信息的应用实例。
Vector clusters with certain attributes in three-dimensional space are usually distributed in an ellipsoidal shape. Extract this part of the information using conventional methods, through complex calculations can be achieved. This paper derives a method that can quickly extract three-dimensional information, called the three-dimensional vector sieve. And introduces an example of how to extract the information of gold mineralized alteration in remote sensing images.
