Abstract: front page image
(EN)Disclosed are an apparatus and a method for reconstructing a road surface blocked area. The apparatus for reconstructing a road surface blocked area according to the present invention comprises: an anomalous point cloud discard logic for discarding anomalous point clouds from three-dimensional point clouds acquired by means of a mobile mapping system (MMS); a blocked area detection logic for detecting a blocked area in an image from which anomalous point clouds have been discarded by the anomalous point cloud discard logic; a point cloud generation logic for generating a virtual point cloud in the blocked area detected by means of the blocked area detection logic; and a blocked area reconstruction logic for projecting each virtual point generated by the point cloud generation logic as a dashed point image, and changing the color of each virtual point within the dashed point image to a greyscale to reconstruct the blocked area.
(FR)La présente invention concerne un appareil et un procédé de reconstruction d'une zone bloquée de surface de route. L'appareil de reconstruction d'une zone bloquée de surface de route selon la présente invention comprend : une logique de suppression de nuages de points anormaux destinée à éliminer des nuages de points anormaux présents dans des nuages de points tridimensionnels acquis au moyen d'un système de mappage mobile (MMS) ; une logique de détection de zone bloquée destinée à détecter une zone bloquée dans une image à partir de laquelle des nuages de points anormaux ont été supprimés par la logique de suppression de nuages de points anormaux ; une logique de génération de nuage de points destinée à générer un nuage de points virtuels dans la zone bloquée détectée au moyen de la logique de détection de zone bloquée ; et une logique de reconstruction de zone bloquée destinée à projeter chaque point virtuel généré par la logique de génération de nuage de points en tant qu'image de point en pointillés, et à changer la couleur de chaque point virtuel au sein de l'image de point en pointillé en une échelle de gris pour reconstruire la zone bloquée.
(KO)도로면 폐색 영역 복원 장치 및 방법이 개시된다. 본 발명의 도로면 폐색 영역 복원 장치는 MMS(Mobile Mapping System)에 의해 획득된 3차원 점군에서 이상 점군을 제거하는 이상 점군 제거 로직; 이상 점군 제거 로직에 의해 이상 점군이 제거된 영상에서 폐색 영역을 검출하는 폐색 영역 검출 로직; 폐색 영역 검출 로직에 의해 검출된 폐색 영역에 가상의 점군을 생성하는 점군 생성로직; 및 점군 생성로직에 의해 생성된 가상의 점 각각을 다시점 이미지로 투영하고, 다시점 이미지 내 가상의 점 각각의 색상을 그레이 스케일로 변경하여 폐색 영역을 복원하는 폐색 영역 복원 로직을 포함하는 것을 특징으로 한다.
