Abstract
(EN) A moving object detection unit (113) extracts a point cloud representing a moving object existing near a moving body from point cloud data obtained by a LiDAR for measuring the area around the moving body. A moving object tracking unit (116) extracts, from the point cloud data, a point cloud within the range of a posterior distribution for a tracked object that is a moving object being tracked and matches the extracted point cloud with the point cloud for the moving object.
(FR) La présente invention concerne une unité de détection d'objet mobile (113) qui extrait un nuage de points représentant un objet mobile existant à proximité d'un corps mobile à partir de données de nuage de points obtenues par un LiDAR pour mesurer la zone autour du corps mobile. Une unité de suivi d'objet mobile (116) extrait, à partir des données de nuage de points, un nuage de points dans la plage d'une distribution postérieure pour un objet suivi qui est un objet mobile qui est suivi et qui correspond au nuage de points extrait avec le nuage de points pour l'objet mobile.
(JA) 移動物体検知部(113)は、移動体の周辺に対する計測を行うLiDARによって得られた点群データから、前記移動体の周辺に存在する移動物体を表す点群を抽出する。移動物体追跡部(116)は、追跡されている移動物体である追跡物体用の事後分布の範囲内の点群を前記点群データから抽出し、抽出した点群に対して前記移動物体の点群とのマッチングを行う。
