| 中文摘要: |
| 成像光谱以其超高的光谱分辨率影像和精细的地物光谱成像能力,已经广泛地应用在地质、环境保护和生物学等领域.受多种不确定性因素影响,成像光谱地物识别从数据获取和处理到应用决策都存在不确定性.这种不确定性又可以分为基于误差的不确定性和基于变异的不确定性.文章以矿物识别为例,从机理的角度探讨了影响数据层面的上述不确定因素,指出虽然成像光谱地物识别受各种因素影响,但地物光谱的形成机理决定了这种不确定性是可以消除的.并给出一些常见的解决理论和方法. |
| 英文摘要: |
| Imaging spectrometry has been applied in geology, environmental protection and biology for its hyper - spectral resolution and refined spectral imaging. Affected by many uncertain influential factors, target recognition of imaging spectrometry has uncertainty from getting and processing data to application and decision - making. The uncertainty can be divided into error - based uncertainty and variation - based uncertainty. Taking minerals identification as an example, this paper discusses uncertain factors affecting data from the mechanism, and points out that such uncertainty can be removed although imaging spectrometry target recognition is affected by different factors. Some common theory and methods to solve the problem are proposed. |
