The “Smart Ingredient Management System” developed by our team integrates cameras and weight sensors to monitor ingredient conditions. Combined with AI technologies such as MediaPipe, OpenCV, and other image recognition models, the system can automatically identify the type, quantity, and storage status of ingredients in the refrigerator, and update the data to the database in real time. The core functions—including ingredient recognition, expiration tracking, and inventory management—are fully designed and implemented by our team. In addition, Gemini 3.0 is utilized to optimize the system, enhancing image recognition accuracy and computational efficiency. Compared to traditional manual input methods, most processes in this system are automated. Furthermore, the system integrates LINE notifications for expiration alerts, visual data analysis dashboards, and voice prompts, providing real-time feedback such as expiration reminders, storage recommendations, and usage priorities. This enables users to quickly understand the status of their refrigerator before cooking or shopping, reducing manual input complexity while effectively minimizing food waste and improving daily convenience.
