1. An information processing device, comprising:
circuitry configured to:
detect a first device from an image;
estimate at least one of a location or a posture of the first device;
acquire, from the first device, first environment information of the first device, wherein
the first environment information includes at least one of a first location or a first posture of a second device,
the second device is detected by the first device, and
the second device is out of a field of view of the information processing device;
calculate at least one of a second location or a second posture of the second device relative to the information processing device, based on the estimated at least one of the location or the posture of the first device and the acquired first environment information;
generate second environment information based on the at least one of the second location or the second posture of the second device and the estimated at least one of the location or the posture of the first device,
wherein the second environment information includes first time information associated with the at least one of the second location or the second posture of the second device; and
determine, based on the first time information, elimination of the at least one of the second location or the second posture of the second device from the second environment information.
