摘　　要：高光谱成像技术具有“图谱合一”的特点,其汇集了传统成像和光谱技术的特点,能同时获得待测农产品样本的图像信息和光谱信息,因此该技术既可以通过成像技术检测物体的外部特征,又可以通过光谱技术得到农产品的内部品质和食用安全性信息,包括品种分类、理化指标测定、真菌感染检测和农药残留检测等。与传统检测方法相比,高光谱成像以其检测过程中前处理简单、无污染、无破坏性的特点,在农产品无损检测领域有所应用。从高光谱成像的理论基础出发,对其图像获取与分析方式进行概述,并阐述了高光谱成像技术在农产品无损检测领域中近五年的研究进展,以期为农产品的品种分类、营养品质和食用安全性评估方法提供参考。The hyperspectral imaging technology has the feature of“image and spectrum in one”,which brings together the features of traditional imaging and spectroscopic techniques,and both image information and spectral information of the agricultural products could be obtained.Therefore,this technology can not only detect the external characteristics of objects by imaging technology,but also obtain the internal quality and food safety information of agricultural products by the spectral technology,including variety classification,physical and chemical index determination,fungal infection detection and pesticide residue detection,etc.Compared with traditional detection methods,hyperspectral imaging has been applied in the field of non-destructive testing of agricultural products due to its simple pretreatment,non-pollution and non-destructive characteristics in the detection process.This review started from the theoretical basis of hyperspectral imaging,and summarized its image acquisition and analysis methods,followed by expounding the research progress of hyperspectral imaging technology in the field of nondestructive testing of agricultural products in the past five years.This review could provide information on the classification and nutritional quality of agricultural products and food safety assessment methods to provide reference.
