Localization System Using Invisible Visual Markers and IR Camera for Wearable Augmented Reality

摘要

To realize an augmented reality (AR) system using a wearable computer, the exact position and orientation of a user are required. We propose a localization method which is based on using an IR camera and invisible visual markers consisting of translucent retro-reflectors. In the method, to stably extract the regions of markers from the captured images, the camera captures the reflection of IR LEDs that are flashed on and off continuously. In experiments, we first describe the quantitative evaluation in computer simulation to decide the alignment of markers in real environments. We then carry out the localization experiments in real environments in which markers are installed based on the marker alignment decided by simulations. Finally, we develop a wearable augmented reality system using the proposed localization system.
