1. An information processing apparatus comprising:
an antenna; and
circuitry including a CPU that is configured by execution of computer readable instructions to
acquire self-position information indicating a self-position of the information processing apparatus in a target region; and
generate, based on the self-position information, absolute position information including area mesh information that indicates a position of a target area mesh containing the information processing apparatus among plural area meshes defined by dividing the target region in a first direction and a second direction such that a division number in the second direction varies for each dividing position in the first direction in the target region, and relative position information that indicates a position of the information processing apparatus in the target area mesh, wherein
the absolute position information includes
first absolute position information that indicates an absolute position of the information processing apparatus in the first direction in the target region, the first absolute position information including first area mesh information that indicates a position of the target area mesh in the first direction in the target region and first relative position information that indicates a position of the information processing apparatus in the first direction in the target area mesh, and
second absolute position information that indicates an absolute position of the information processing apparatus in the second direction in the target region, the second absolute position information including second area mesh information that indicates a position of the target area mesh in the second direction in the target region and second relative position information that indicates a position of the information processing apparatus in the second direction in the target area mesh, and wherein
the circuitry is further configured to
receive through the antenna other first relative position information and other second relative position information of a target object both transmitted from a transmitter of the target object, a combination of the antenna and the transmitter having a maximum communication distance R within which the other first relative position information and the other second relative position information of the target object transmitted from the transmitter are receivable through the antenna, and the maximum communication distance R of the combination of the antenna and the transmitter meeting a condition that D is longer than 2R where D is a length of a side of the target area mesh, and
generate absolute position information of the target object, based on the first area mesh information and the second area mesh information of the information processing apparatus and the other first relative position information and the other second relative position information of the target object.
