Raman spectrum detection method for article inspection

The invention discloses a Raman spectrum detection method for article inspection. The method includes: a Raman spectrum acquisition step: acquiring sampling the Raman spectrum of a to-be-detected article; and a comparison and determination step: comparing the acquired Raman spectrum of the to-be-detected article with the Raman spectrum of a standard article stored in a standard database to judge whether the to-be-detected article matches with the standard article. And the comparison and determination step includes: using a support vector machine to classify the Raman spectrum of the to-be-detected article so as to realize comparison of the Raman spectrum of the to-be-detected article with the standard article stored in the standard database. 本发明公开了种用于物品查验的拉曼光谱检测方法，包括以下步骤：拉曼光谱采集步骤：采集待检物品的拉曼光谱；和比对和判定步骤：将采集的待检物品的拉曼光谱与标准数据库中存储的标准物品的拉曼光谱作比对，以判定待检物品是否与标准物品匹配。所述比对和判定步骤包括：采用支持向量机对待检物品的拉曼光谱进行分类，以实现待检物品的拉曼光谱与标准数据库中存储的标准物品的拉曼光谱的比对。
