典型目标地面光谱信息系统设计与实现

Design and construction of the typical ground target spectral information system

针对现有地物波谱库数据采集传感器单一、地物种类划分泛化性弱以及缺乏有效集成最新光谱分析模型等问题,提出构建典型目标地面光谱信息系统,对地面光谱数据获取、分析、处理和综合信息提取等技术进行科学设计和集成,并基于客户端层和服务器层(C/S)结构设计实现系统的信息表达。以岩矿和土壤重金属提取为例开展了示范研究。研究表明,系统达到了高效、快速和准确挖掘光谱蕴含的丰富地物信息的研究目标,为地物识别、资源勘查和生态环境评价等工作提供了技术支撑。

The spectral data in existing object spectrum library have some disadvantages,such as single data acquisition sensor;unreasonable ground objects classification and no efficient integration of the latest spectral analysis models.In order to solve these problems,this paper proposes a typical target ground spectral information system.The ground spectral data acquisition,analysis,processing and integrated information extraction are designed and integrated,and the information expression of the system is constructed based on the client layer and the server layer(C/S)structure.Taking the extraction of rocks,mines,and heavy metals from soils as an example,the authors conducted a demonstration study.The research shows that the system has achieved the goal of efficient,fast and accurate excavation of the rich ground information contained in the spectra,thus providing technical support for land identification,resource exploration and ecological environment evaluation.
