The work aims to establish a fast, accurate, and non-destructive inspection and classification method for plastic packaging tapes. 52 samples of plastic packaging tape were collected from different sources through hyperspectral data in the wavelength range of 350-990 nm, and the samples were smoothed with Savitzky Golay. Principal component analysis was also used to reduce the dimensionality of the samples. K-Means clustering was conducted on the extracted principal components, and a radial basis function neural network (RBFNN) and BP neural network model (BPNN) was established based on the clustering results. There were significant differences in the hyperspectral spectra of the packaged sample at 400-500 nm and 600-700 nm. A total of 5 principal components with initial feature values greater than 1 were extracted in the experiment, which could explain 96.633% of the original data. The plastic packaging tape samples were clustered into 6 categories, with a Calinski Harabasz index of 28.76 for K-means and a classification accuracy of 86.7% for RBFNN. The classification accuracy of BPNN was 98.1%. BPNN had better classification performance. Research has shown that neural network has high accuracy in the classification and processing of hyperspectral spectra, and it has also verified the feasibility and scientificity of hyperspectral recognition in the detection of plastic packaging tape type evidence, providing a new inspection method for public security organs.
