【摘要】：岩心高光谱编录是目前深度挖掘地质资料、实现地质找矿突破的有效支持技术之一。该技术实现了高光谱遥感矿物识别优势与钻探技术深部岩层采样特点的结合。针对国家重大科学仪器设备开发专项"岩心光谱扫描仪研发与产业化"支持研发的国内首台岩心光谱扫描仪CMS350A数据采集机理和获取的岩心图像及光谱数据的特点,对岩心光谱扫描数据预处理方法开展研究,提出了基于标准板的岩心扫描图像增强方法、图谱分析结合的干扰光谱识别和校正技术及岩心自动提取和拼接模型,实现了对岩心光谱扫描数据的实时、可靠处理,为后期岩心光谱分析、理化参数反演和矿物分析等工作奠定了基础。
[Abstract]:The hyperspectral cataloguing of cores is one of the effective supporting techniques for mining geological data in depth and realizing the breakthrough in geological prospecting.This technique combines the advantages of hyperspectral remote sensing mineral identification with the sampling characteristics of deep strata of drilling technology.In view of the principle of CMS350A data acquisition and the characteristics of core images and spectral data acquired by the first core spectral scanner in China, which is supported by the development and industrialization of the core spectrum scanner, which is a major national scientific instrument and equipment development project,The pretreatment method of core spectral scanning data is studied, and a core scanning image enhancement method based on standard plate is proposed. The interference spectrum recognition and correction technology combined with map analysis and core automatic extraction and stitching model are proposed.The real-time and reliable processing of the core spectral scanning data is realized, which lays a foundation for the later core spectral analysis, physical and chemical parameters inversion and mineral analysis.
