Abstract: A position management device includes: a sensor which acquires point cloud data in each unit time; a pair selection unit which selects a pair of the coordinates between first point cloud data and second point cloud data; and a position estimation unit which estimates a position of the moving object by making both coordinates of the pair selected by the pair selection unit correspond to each other and performing positioning processing of the first point cloud data and the second point cloud data. The pair selection unit selects the pair of the coordinates by pairing a first point belonging to the first point cloud data and a second point belonging to the second point cloud data in a case where a difference between a direction of the first point and a direction of the second point is equal to or smaller than a predetermined first threshold.
