农产品病虫害高光谱成像无损检测的研究进展

Research progress on hyperspectral imaging in nondestructive detection of agricultural products disease and pest

高光谱成像是一种新兴的无损快速检测技术,可以同时获取研究对象的图像和光谱信息,集成了光谱分析和图像处理的优势,已成为农产品病虫害信息快速、无损检测的重要手段之一,在农产品的溃疡病、褐斑病、白粉病、黑星病、腐烂、虫蛀等病虫害无损检测中的应用越来越广泛。本文简述了高光谱成像系统,总结分析了其在水果、蔬菜、肉类、谷物等农产品病虫害无损检测中的国内外最新研究进展,提出了农产品病虫害高光谱成像技术检测的未来研究发展方向,以期对相关研究人员的研究工作提供参考。

Hyperspectral imaging is an innovative nondestructive and rapid detection technology. It can get the image and spectral information of the researched object at the same time. It integrates the advantages of spectroscopic analysis and imaging processing. Hyperspectral imaging has been more and more widely used in nondestructive detection for agricultural products＇ disease and pest such as canker,leaf spot,powdery mildew,scab,spoilage,and so on. In this paper,the system of hyperspectral imaging is presented briefly. The latest progress of hyperspectral imaging in detecting agricultural products＇ disease and pest is investigated,including fruit,vegetable,meat and corn. Finally,the development direction of future research in agricultural products disease and pest detection using hyperspectral imaging is proposed,which provides references for related researchers.
