Abstract

複合現実空間において作業を行う場合,仮想物体の選択,移動,加工など,様々なデバイスが用いられている.デバイスを用いて仮想物体を直接操作するためには,デバイス位置姿勢を取得する必要がある.これまでは,大規模なモーションキャプチャシステムや磁気センサ,人為的なマーカを用いてきたが,規模や測定範囲,外乱の影響など,デバイスの位置姿勢推定に利用するにはいくつかの問題があった.そこで本研究ではカメラによる画像認識と,デバイス内蔵姿勢センサを併用し,デバイス形状情報とLEDアクティブマーカを用いて位置姿勢推定を行う,ハイブリッド型位置姿勢決定法を提案し,実験の結果,安定したトラッキングを実現した.

The users have variety of hand-held devices to interactive manipulations in mixed reality space. The position and posture estimation of device are required for direct manipulation with virtual objects. Fiducial markers or large-scale motion capture system are generally used for estimation. Therefore they can be identified easily. However, they had some problems that estimation stability and portability of device are deteriorated by these system scale, determining area and disturbance. To cope with this problem, we propose a hybrid method to tracking for hand-held devises that combine vision-based registration with pose information from physical 3DOF orientation sensor. In vision-based method, estimate with device forms and LED active markers. As a result, this method was stably tracking the device.
