| Summary: | This study aims to enhance the efficiency and accuracy of nondestructive testing (NDT) for identifying mechanical damage in apples. Current methods have limitations in detection efficiency and require significant human resources. We conducted a study using laser relaxation spectroscopy and developed a single-wavelength system to collect spectral data from damaged and undamaged Red Fuji apples. The data was pretreated using the Min-Max standardization algorithm and analyzed using pattern recognition models including the depth extreme learning machine (DELM), SSA-DELM (optimized by the sparrow search algorithm), and backpropagation (BP) neural networks. We introduced neural network visualization to improve accuracy during BP neural network analysis. The BP neural networks achieved the highest accuracy of 94.74% among the models tested. To further enhance accuracy, we proposed an optimized multicount measurement classification recognition (MMCR) model, which improved accuracy to 97.5% with ultrahigh detection speed. The proposed method offers advantages such as ease of operation, affordability, and fast detection, providing a novel approach to rapid fruit quality assessment. |
