1. An information processing system comprising:
a specification apparatus comprising a first processor and configured to specify a person present at a predetermined position as a specific person;
at least one recognition apparatus comprising at least one processor and configured to recognize a person in a geographic range corresponding to the respective recognition apparatus as an unspecific person; and
an information processing apparatus comprising a second processor and configured to:
acquire a movement history indicating a temporal change in a position of a first unspecific person by analyzing a result of recognition by the at least one recognition apparatus;
determine whether the specific person and the first unspecific person are identical, based on a time and the predetermined position at which the specification apparatus has specified the specific person and the movement history of the first unspecific person; and
control a data storage apparatus to store the movement history of the first unspecific person in association with the specific person, in a case in which the specific person and the first unspecific person are determined to be identical,
wherein
the at least one recognition apparatus includes a first recognition apparatus comprising a third processor, and
the information processing apparatus is configured to:
determine, by analyzing a result of recognition by the first recognition apparatus, a first position and a first velocity vector of the first unspecific person at a first time at which the first recognition apparatus has recognized the first unspecific person; and
determine, based on the first time, the first position, and the first velocity vector, an estimated position of the first unspecific person at a past time prior to the first time,
the at least one recognition apparatus further includes a second recognition apparatus comprising a fourth processor, and
the information processing apparatus is configured to:
determine, by analyzing a result of recognition by the second recognition apparatus, a second time at which the second recognition apparatus has recognized a second unspecific person and a second position of the second unspecific person at the second time; and
determine whether the first unspecific person and the second unspecific person are identical, based on a comparison of the past time and the estimated position with the second time and the second position.
