- Abstract:
-
Foreign objects in pharmaceuticals are typically small, which causes difficulty for lightweight algorithms to detect them accurately, while high-performance algorithms often struggle with real-time capability. To balance real-time performance and accuracy, a deep learning distillation algorithm is proposed for the precise and rapid detection of foreign objects in pharmaceutical liquid images. The teacher network incorporates a semantic feature-based upsampling method to enhance the feature disparity between teacher and student networks. In addition, random noise is added to the training images of the student network to improve robustness in high-noise detection scenarios. To validate the effectiveness of the algorithm, a pharmaceutical liquid foreign-object dataset is collected using lamp inspection equipment, and comparative experiments are conducted. After distillation, the average precision improves by 4.1%, and the model achieves 65 frames per second, which surpasses current state-of-the-art methods. Extended experiments on the Tianchi liquor dataset show a 3.9% improvement in detection accuracy, which demonstrates the applicability of the model in similar scenarios.
