Abstract: Provided is an occupant detection device including an obtaining part obtaining indicating intensities of reflected waves generated by transmission waves being reflected by objects, the transmission waves being transmitted into an interior of a vehicle. A generating part generates, based on the reflected-wave information, a piece of first point cloud information indicating changes in intensity of corresponding ones of the reflected waves in a first detection region set for each seat row among seating regions; and a determining part determining, for each of the seat rows, whether an occupant is present in a corresponding one of the first detection regions, based on a corresponding one of the pieces of first point cloud information when the vehicle is stopped. The pieces of first point cloud information each include point cloud corresponding to an object present across a plurality of seating regions in a corresponding one of the first detection regions.
