目标多维特征数据库设计与实现

Design and implementation of target multidimensional feature database

针对地物目标空间、光谱和偏振等多维信息管理不够全面、目标多维特征利用不足等问题,提出构建目标多维特征数据库的方法。基于SQL Server数据库和关系模型,利用C#语言和.NET平台下的WPF界面框架和Entity Framework数据访问技术,设计了四层体系结构以及四类功能模块,开发了包括空间、光谱和偏振等多维信息在内的数据库系统,并针对多维样本设计了包含属性信息的编号形式。该系统提高了目标多维信息的管理效率,并且为地物目标的探测、分类和识别等应用提供支持。

As the management of ground target multidimensional information such as space,spectrum and polarization is in?comprehensive,and target multidimensional features are underutilized,a method of constructing target multidimensional featuredatabase is proposed.Based on SQL Server database and the relational model,C#language,WPF UI framework of the.NETplatform,and the Entity Framework data access technology are utilized to design a four?layer system architecture and four func?tional modules,develop the database system containing multidimensional information such as space,spectrum and polarization,and design coding form containing attribute information for multidimensional samples.The system improves the management effi?ciency of target multidimensional information,and provides support for ground target detection,classification and recognition.
