To improve the detection accuracy of a fallen thing.SOLUTION: The fall detection device includes: an acquisition unit that acquires point group data detected by sensors in a sensing area; an estimation unit that estimates a fall detection point corresponding to a fallen thing in a sensing area by using matching processing of the point group data; and a determination unit that determines the reliability relevant to the state of the fallen thing based on the fall detection point and the point group data corresponding to the fall detection point.SELECTED DRAWING: Figure 1 【課題】転落物の検知精度を向上する。【解決手段】転落検知装置は、センサがセンシング領域において検知した点群データを取得する取得部と、点群データのマッチング処理を用いてセンシング領域における転落物に対応する転落検知点を推定する推定部と、転落検知点と転落検知点に対応する点群データとに基づいて、転落物の状態に関する信頼度を決定する決定部と、を備える。【選択図】図１
