遥感影像内容的语义查询算法与应用

Research on Application and Semantic Query Algorithm of Remote Sensing Images

海量遥感影像数据如何进行方便快捷的查询检索与定位,是影像数据存储管理部门所面临的主要问题,同时也是制约影像数据为用户提供更好服务的瓶颈。本文主要分析了当前遥感影像数据库查询检索的几种方式和它们的利弊,进而提出一种在近乎海量的遥感数据中简单、方便、快捷的算法与实现思想。并在已有的影像数据库引擎原型系统上,设计出一种检索查询遥感影像内地物的方法。这种方法以矢量要素的空间信息和属性信息为引导,快速准确的定位地物所在的影像块,为遥感影像的有效管理和应用提供了一种可行的方法。

This article mainly analyzed the pros and cons of remote sensing database and several information retrieval ways that can achieve remote sensing data in a simple, convenient, fast search algorithm to meet the needs of users. Based on the existing image database engine prototype system which has, the author designs a kind of method for retrieval inquiry remote sensing image interior ground feature. This method takes the vector essential factor spatial information and the attribute information as the guidance, the fast accurate localization thing is at the image tile, which provides a feasible method for the remote sensing image effective management and the application.
