High Precision Contraband Detection Method for Transportation Safety
To improve the accuracy and efficiency of contraband detection with X-ray,and to solve the problem of security personnel fatigue and reduced inspection accuracy caused by long-time and high-intensity security work,taking the contraband detection in baggage items as the object,the high precision X-ray contraband detection method is proposed.The method combines artificial intelligence technology with security checkers,and utilizes deep learning-based computer vision technology to automatically detect and label contraband in X-ray images.The high precision X-ray contraband detection method employs a variety of innovative techniques in its design to ensure its efficiency and reliability in practical applications.Specifically,the high precision X-ray contraband detection method employs the α-IoU loss function to alleviate the problem of uneven expression of positive and negative samples.It also combines the SimCSPSPPF spatial pyramid pooling method and the convolutional block attention mechanism to fuse multilevel semantic information and generate rich feature expressions,which significantly enhances the detection performance,enabling the high precision X-ray contraband detection to maintain high detection accuracy and stability even in complex X-ray image environments.In addition,the method also utilizes Merge great value suppression to reduce the false detection situation,and enhance the detection accuracy.From the experimental results,the high precision X-ray contraband detection method achieves high detection accuracy on both EDS dataset and VOC dataset in a well-configured environment.Meanwhile,the mAP on EDS dataset reaches 81.20％,which shows good detection accuracy and stability to meet the needs of actual security checking work.The average enhancement reaches 10.81％comparing with other widely used target detection models in recent years.The result indicates that the high precision X-ray contraband detection method can effectively improve the accuracy and efficiency of contraband detection,and simultaneously significantly enhance the intelligence level of security check,providing the important support for safeguarding public transportation safety.
