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