1. An estimation system that estimates an arrangement of objects, the estimation system comprising an estimation unit that obtains information related to an arrangement pattern of the objects as first information and obtains, from wireless devices respectively connected to the objects, information including response times between the wireless devices as second information to estimate the arrangement of the objects based on the first information and the second information,
wherein the estimation unit:
estimates a combination of the objects and the wireless devices in the arrangement pattern based on the first information and the second information in an arrangement space (DS) in which the wireless devices are respectively connected to the objects in a one-to-one relationship;
obtains specific information of the objects respectively connected to the wireless devices from the wireless devices; and
associates the specific information of the objects with the objects in the arrangement pattern based on the combination of the objects and the wireless devices and the specific information of the objects in the arrangement pattern.
