研究目的
To design an enhanced Augmented Reality (AR)-based visualization tool with real-time sensing capability in a tagged environment to improve user-environment interaction and productivity in various settings.
研究成果
The X-Vision system successfully demonstrates the projection of 3D holograms encoded with sensing information onto physical objects, enhancing user-environment interaction. The study proposes optimal working ranges for reliable system performance and suggests future packaging of the camera and reader onto a head mount to eliminate the need for separate RFID infrastructure.
研究不足
The system's performance is affected by the camera-object and tag-reader separation distances, with a recommended working range of 40-75 cm between the camera & target object and less than 100-150 cm between tagged objects & readers for reliable visualization.
1：Experimental Design and Method Selection:
The system combines object’s pose information estimated by a depth camera and object’s ID & physical attributes captured by RFID tags for augmented visualization.
2：Sample Selection and Data Sources:
Uses an office space equipped with RFID infrastructure and common office/household objects like coffee cups and water bottles.
3：List of Experimental Equipment and Materials:
Intel RealSense D415 RGB-D camera, HoloLens, Impinj Speedway Revolution RFID reader, Laird Antennas, Smartrac’s paper RFID tags, EM 4325 IC for temperature sensing.
4：Experimental Procedures and Operational Workflow:
Captures color and depth images for object identification and pose estimation, collects tag-data reflecting object’s physical properties, and superimposes augmented information onto the object.
5：Data Analysis Methods:
Evaluates pose estimation quality using point-to-point residual error and compares recognition accuracy and running time of different methods.
