OBJECT IDENTIFICATION DEVICE, OBJECT IDENTIFICATION METHOD, AND RECORDING MEDIUM

An object identification device includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: compare a captured image against a plurality of identification images for identifying objects; and determine, after the comparison result indicates that a plurality of objects are included in the captured image, whether or not the plurality of objects are same objects, based on a first parameter indicating a geometric relation between the identification images and a second parameter indicating a geometric relation between identification image related to each identified object and the captured image.
