【摘要】 高光谱成像技术是一种传统图像及光谱的融合技术,可以同时获取研究对象的空间及光谱信息。由于图像数据能反映农产品的外部特征、表面缺陷及污斑情况,而光谱数据又可以对物体内部物理结构及化学成分进行分析。因此,近几年在农产品品质无损检测中引起越来越多的关注,成为一个研究热点。为了跟踪国内外的最新研究成果,对高光谱反射及荧光成像技术应用于农产品(水果、蔬菜、肉类、谷物等)的外部品质检测进行了分类综述,以期为高光谱技术在农业方面更广阔的应用提供参考。更多还原

【Abstract】 Hyperspectral imaging is an emerging technique that integrates conventional imaging and spectroscopy to obtain both spatial and spectral information from a studied object simultaneously.The images data can reflect the external features,surface defects and contamination.The spectra data can analyze physical structure and chemical composition in studied object.Therefore,hyperspectral imaging technology causes more and more attention,and has become a hot research topic recently.In order to track the latest research developments at home and abroad,application of hyperspectral reflectance and fluorescence imaging techniques to nondestructive detection of agricultural products external quality was reviewed,which would provide reference for application of hyperspectral imaging to agriculture.更多还原
