Beschreibung
Zusammenfassung:	There is provided a position estimation device for estimating a position of an industrial vehicle equipped with a laser scanner capable of acquiring point cloud data by scanning a laser beam and a camera capable of acquiring an image in a predetermined direction The position estimation device includes an acquisition unit configured to acquire the point cloud data and the image, an estimation unit configured to estimate the position of the industrial vehicle based on at least one of the point cloud data and the image, and an extraction unit configured to extract, from the point cloud data, valid point cloud data that is usable for estimating the position. In a case where the number of pieces of valid point cloud data is equal to or greater than a predetermined number, the estimation unit estimates the position of the industrial vehicle by using the valid point cloud data, and in a case where the number of pieces of valid point cloud data is less than the predetermined number, the estimation unit estimates the position of the industrial vehicle by using the image.
