摘要
为了研究荧光光谱技术在白酒检测、识别中的应用,对五粮液和用于比对的茅台醇、高沟等一些常见白酒的荧光光谱进行了检测,得到了3维荧光光谱图,发现五粮液与其中大部分白酒的3维荧光光谱有显著不同,但与同属浓香型白酒的茅台醇有较大相似之处。为识别出五粮液,首先提取出表征白酒荧光光谱的特征参量,再借助最小二乘支持向量机对其进行分类识别,从而准确地将五粮液与其它白酒区分开来。结果表明,提取的荧光光谱特征参量可以用于识别五粮液,并且提取参量过程由计算机处理,提高了识别效率。该方法可以推广应用于识别其它白酒,为快速识别白酒提供了一种实用、有效的途径。
Abstract
In order to achieve the application of fluorescent spectroscopy in the detection and identification of liquor, the three-dimension fluorescent spectrograms of Wuliangye wine and some common liquor such as Maotaichun and Gaogou, were drafted through the detection of their fluorescent spectra. These spectrograms show that the three-dimension fluorescent spectrogram of Wuliangye is distinct from those of the common liquors but similar to that of Maotaichun. To distinguish Wuliangye from other samples, firstly the characteristic parameters were extracted from its fluorescent spectra, and then those parameters were classified by the aid of least-squares support vector machine. Thus Wuliangye was distinguished from other liquors. The result indicates that the extracted characteristic parameters of fluorescent spectra can be used to identify Wuliangye, and the process of extraction is completed by computer, which improves the efficiency of identification. This method can be applied to identify other liquors and provide a more practical and effective way for liquor identification.
