| 中文摘要: |
| 基于薄膜干涉分光技术开发了多光谱图像采集分析系统样机,样机由分光滤光片、CCD相机、逻辑控制组件和计算机终端软件等组成,并在农产品检测、成分检测等方面开展了多光谱检测技术的实验研究.实验表明,多光谱成像系统能够进行高分辨率的光谱图像采集,并进行光谱重建和聚类等分析.在农产品检验中利用多光谱成像技术能够将霉变的黄豆与优质黄豆进行快速区分;在电解液浓度和成分检验中能够将不同浓度或不同成分的液体进行识别;在笔墨检验中能够将不同油墨的笔迹进行准确有效地判别. |
| 英文摘要: |
| One type of multi-spectrum imaging system based on film interference technique is discussed. A prototype of multi-spectrum imaging machine is developed, which consists of a band-pass filter, a CCD, logic control components and computer analysis software. Experiments such as inspection of agricultural products and physical composition are carried out. The result shows that the imaging system can realize spectral image acquisition at a high resolution and analyze the reflectance spectrum reconstruction and image classification accurately. The system is also applied in the inspection experiment of mouldy beans, electrolyte composition and density, and scribbled signatures with different pens. |
