Intelligent Security Image Judgment at Beijing Railway Station of Beijing Railway Bureau Group Co., Ltd.

Beijing Railway Station is an important gateway for the capital's railway passenger transport, with concentrated daily passenger flow and heavy security inspection tasks. The prohibited items that passengers may carry in their luggage are diverse in type and complex in form, placing high demands on the identification ability and response speed of image judgment personnel. The project deployed an intelligent security image judgment system at Beijing Railway Station. Through the collection and analysis of security inspection image data, it enables real-time detection and warning of firearms and ammunition, flammable liquids, explosive materials, knives, sharp instruments, blunt instruments, military and police equipment, tools, and flammable and explosive items concealed in passenger luggage.

Through its proprietary image data segmentation method, the system conducts comprehensive scanning of passenger packages in layers and by category, assisting check-in personnel in quickly identifying prohibited items. The system is compatible with security inspection machines of different brands and can be directly integrated into existing security inspection lanes, reducing equipment replacement costs. Utilizing powerful prohibited item recognition algorithms, the system can precisely identify flammable and explosive liquid components carried in passenger packages, such as alcohol, kerosene, gasoline, diesel, pesticides, paint, perfume, floral water, and various alcohol-containing spray products, and accurately labels the liquid components, greatly improving the detection rate of liquid items.

During operation, the intelligent image judgment system complements the work of security personnel: the system performs preliminary analysis of images and provides prompts, while image judgment personnel conduct review and confirmation based on the system's prompts, which not only accelerates the image judgment speed but also retains the flexibility of manual judgment. For special periods, special passengers, and other situations, the system supports security personnel in adjusting inspection priorities based on on-site conditions.

After the project was put into use, the efficiency of security image judgment at Beijing Railway Station has been improved, and the ability to intercept prohibited items has been enhanced, providing strong support for the station's daily passenger transport organization and passengers' safe travel.
