| Abstract(in English) | It is necessary to precisely measure position and orientation of a user in order to realize an augmented reality (AR) system with a wearable computer. We have proposed a method of measurement user's position and orientation for wearable AR without undesirable visual effects in indoor environments. The method can estimate the user's position and orientation by recognizing invisible visual markers pasted up on the ceilings or walls using a infrared camera. To realize this method, exact 3D position information of visual markers is required in advance. However, much cost is necessary to set up and calibrate the markers on the ceiling in a wide environment. In this paper, we propose a localization system which can estimate the user's position and orientation with high accuracy by using marshaled invisible visual markers printed on wallpapers. In a experiment, the accuracy of two types infrared cameras' position and orientation is evaluated. |
