1. A mesh structure facility detection device that detects data corresponding to a mesh structure facility from three-dimensional structure data representing a space including an outer shape of an object, the mesh structure facility detection device comprising:
a processor; and
a memory that includes instructions, which when executed, cause the processor to execute:
projecting the three-dimensional structure data in a predetermined direction to obtain two-dimensional structure data; and
detecting a point included in a region in which the two-dimensional structure data has a density of more than or equal to a predetermined threshold value as a point corresponding to the mesh structure facility.
