研究目的
To propose a novel indoor localization system utilizing LED-based VLC beaconing infrastructure for real-time localization and tracking of moving objects equipped with an ordinary camera.
研究成果
The proposed system provides fast and accurate localization and tracking of moving objects in real-time with accuracy in the low centimeter range. It is fault-tolerant against false detections and can operate with inexpensive cameras.
研究不足
The system requires the camera to face upwards and may be sensitive to inaccurate beacon positioning and detection errors. The accuracy can be affected by geometric dilution of precision at certain locations.
1：Experimental Design and Method Selection:
The system localizes and tracks a moving object using an ordinary camera facing upwards, with a novel Heuristic Inscribed Angle Localization (HIAL) method for fast and robust localization.
2：Sample Selection and Data Sources:
The system uses modulated LED lights as anchor points and a greyscale camera equipped with a fisheye lens for detection.
3：List of Experimental Equipment and Materials:
LED beacons, a greyscale camera with fisheye lens, and a data processing unit (PC).
4：Experimental Procedures and Operational Workflow:
The camera detects VLC codes from LED beacons, processes the images to identify and track beacons, and estimates the object's position using HIAL.
5：Data Analysis Methods:
Comprehensive error analysis and real test measurements are conducted to evaluate the system's accuracy and performance.
