An estimation device (10) is provided with a first acquisition unit (110), a second acquisition unit (130), a division unit (150), a ratio value calculation unit (170), and an estimation unit (190). A first acquisition unit (110) acquires point cloud data at a plurality of timings obtained by a sensor mounted on a moving body. A second acquisition unit (130) acquires map information. A division unit (150) divides each piece of point cloud data acquired by the first acquisition unit (110) into a plurality of predetermined regions. A ratio value calculation unit (170) calculates, for a first region and a second region different from the first region, a ratio value indicating a correlation ratio between each data point in the region and map information. The estimation unit (190) uses the intensity of the correlation between the ratio value of the first region and the ratio value of the second region, which are obtained by shifting the time or position, to determine an estimated change point at which the content of the map information is estimated to be different from the actual situation.

    推定装置(10)具备第一取得部(110)、第二取得部(130)、分割部(150)、比率值算出部(170)及推定部(190)。第一取得部(110)取得用搭载于移动体的传感器得到的多个定时的点云数据。第二取得部(130)取得地图信息。分割部(150)将用第一取得部(110)取得的各点云数据分割为规定的多个区域。比率值算出部(170)对于第一区域及与第一区域不同的第二区域,算出表示区域内的各数据点与地图信息的关联比率的比率值。推定部(190)使用使时间或位置偏移而成的第一区域的比率值与第二区域的比率值的相关的强度,确定被推定为地图信息的内容与实际情况不同的推定变化地点。
