• Intelligent Recognition and Security Algorithm Project
  I contributed to the development and deployment of an intelligent inspection and violation monitoring system for the State Grid. Using deep learning and a gRPC microservices architecture, I supported the configuration, data labelling, and optimisation of the YOLOv5 model, improving the system's accuracy in detecting various safety violations and unauthorised intrusions in real-time.
• Violation Recognition and Intelligent Inspection System
  I participated in building a real-time monitoring system for construction sites, where I helped develop algorithms for detecting unsafe behaviours, such as phone use, smoking, and lack of protective gear. My role included assisting with data annotation and model training, ensuring the system could accurately identify violations in different environments and camera setups.
• China Railway Intelligent Recognition and Strategy Development
  I contributed to the creation of multiple strategies for China Railway’s intelligent recognition system. This included helping develop models for detecting incidents such as fighting, escalator congestion, and illegal vehicle operations. My involvement focused on supporting model training, strategy integration, and real-world application of these safety monitoring systems.
