1. An information processing device comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute instructions to:
extract a feature value of an object in a captured image obtained by capturing a pre-passing region of a gate before the object is located in a predetermined range, the predetermined range being set immediately in front of the gate and located at a preset distance from the gate, and store matching information relating to matching of the object based on the feature value;
estimate a distance from the gate to the object in the captured image; and
based on the estimated distance, perform a matching determination by using the stored matching information of the object located in the predetermined range with respect to the gate.
