摘要
高光谱图像技术结合了计算机图像与光谱技术两者的优点,是农畜产品品质检测技术的发展趋势。阐述了农畜产品品质检测中高光谱图像技术的硬件组成和图像的获取方法。介绍了高光谱图像技术在农畜产品品质检测中的应用现状以及数据处理方法,重点分析了不均匀二次差分算法和独立分量分析算法。对高光谱图像技术应用于农畜产品品质检测的技术发展提出了建议。
A tendency of nondestructive inspecting technology for quality and safety of agricultural and poultry products is a hyperspectral imaging system, which possesses the advantages of both computer vision and spectroscopy inspecting technologies. The methods of acquiring hyperspectral imaging in inspecting of quality and safety of agricultural and poultry products were introduced in this paper. The inspecting technology of interior quality of kiwifruit, bruise and contamination in apple, poultry contamination and tomato maturity sorting by means of hyperspectral imaging were discussed. The new process methodology of data for hyperspectral imaging was analyzed and future research aspects were pointed out.
