Abstract: To solve the problems of low retrieval rate, high storage and manual disposal costs of lost items at stations, this paper designed and implemented a lost and found management system. The system was based on the image recognition technology of YOLO (You Only Live Once) algorithm to automatically classify lost items and match them with a database. The paper designed an intelligent access module for ID cards to implement automatic registration, storage, and retrieval of lost identification type items through out of order storage and facial recognition technology. Practical application has shown that the system can significantly improve the efficiency of item retrieval, reduce labor costs, and provide support for the digital upgrade of railway services.
