Raisin identification model and establishment method thereof

The invention relates to a raisin identification model and an establishment method thereof. The invention relates to a raisin identification model establishment method, which comprises: (1) carrying out near infrared spectrum measurement on the pericarp and the pulp of a raisin sample to obtain the spectrum data of the pericarp and the pulp; and (2) performing baseline correction on the spectral data of the peel and the pulp, performing feature extraction through PCA, performing feature fusion, and establishing a classification model to obtain the raisin identification model. 本发明为一种葡萄干鉴别模型及其建立方法。一种葡萄干鉴别模型的建立方法，包括以下步骤：(1)对葡萄干样本的果皮、果肉进行近红外光谱测量，获得果皮和果肉的光谱数据；(2)对所述的果皮和果肉的光谱数据进行基线校正后，通过PCA进行特征提取后，进行特征融合，再建立分类模型，得所述的葡萄干鉴别模型。
