Abstract: An obstacle detection apparatus acquires a three-dimensional map representing a three-dimensional position of each of a plurality of points of a facility and position information representing a position of a user. The obstacle detection apparatus determines a detection range as a detection target for an obstacle region from a region around the position of the user on the three-dimensional map by using the three-dimensional map and the position information. The obstacle detection apparatus detects the obstacle region from the detection range.
