摘　　要： 从光谱成像识别机理出发,概述了光谱成像识别的最新应用,较为详细的讨论了多光谱信息获取以及多光谱识别算法两项关键技术。在多光谱信息获取方面,列举了国内外多种多光谱成像传感器的设计方案,并给出了优缺点评述。在识别算法方面,以目标与诱饵的光谱特性为前提,以光谱识别中是否融合时间、空间信息为分类依据,分别讨论了单一光谱维、时序光谱维,以及空间光谱维上的聚类识别特征选择问题,并给出了几种识别算法的原理。 The current applications of spectrum imaging recognition are summarized based on spectrum imaging recognition mechanism.Two key technologies,multi-spectral information acquirement and multi-spectral recognition,are discussed detailed.In the area of multi-spectral information acquirement,design schemes of typical multi-spectral imaging sensors are enumerated,and the advantages and shortcomings of which are compared.In the area of recognition algorithm,based on spectrum characteristics of target and decoy,the problem selecting clustering recognition character in single spectrum dimension,sequence spectrum dimension and space spectrum dimension are discussed respectively,and principles of some recognition algorithms are presented.
