          <datacite:description xml:lang="ja" descriptionType="Abstract">本論文では，道路環境に設置した複数台のLiDARにより物体(車，二輪車，人物)を協調追跡する方法を提案する．各LiDARはエレベーションマップ上で背景差分法により観測値から物体を検出する．そして，物体により占有された格子の位置をサーバに送信する．サーバは物体に関する格子をクラスタリングし，物体の運動(位置と速度)と物体形状(機首方向と大きさ)を推定(追跡)する．物体の運動と形状を同時追跡するため，乗法誤差モデル拡張カルマンフィルタを利用する．マルチターゲット環境においても正しい追跡を実現するため，ルールに基づくデータ対応付けと追跡管理を導入する．道路環境における2台のLiDARによる物体追跡のシミュレーション結果より，提案手法の性能を示す．</datacite:description>
          <datacite:description xml:lang="en" descriptionType="Abstract">This paper presents a cooperative tracking of objects, such as cars, two-wheelers, and people, using networked light detection and rangings (LiDARs) set in a road environment. Each LiDAR detects objects from the LiDAR measurements using a background subtraction method on an elevation map and sends the positions of cells occupied by objects to a central server. The central server clusteres object cells and estimates (tracks) the motions (positions and velocities) and shapes (heading angles and sizes) of objects. The multiplicative error model extended Kalman filter is utilized to simultaneously track the motions and shapes of objects. A rule-based data association and track handling are introduced to perform correct tracking in a multi-target environment. Simulation results of object tracking using two LiDARs in a road environment show the performance of the presented method.</datacite:description>
