Coin identification apparatus, coin processing apparatus, and coin identification method

Abstract

A coin identification apparatus includes: a line sensor that detects line image data of a coin being conveyed, the coin being subject to identification; an acquisition unit that acquires the line image data at predetermined sampling intervals; an estimation unit that calculates, for each of the acquired line image data items, a similarity between the acquired line image data and reference line data for each angle, the reference line data being a part of reference pattern image data indicating a coin having a reference pattern, the estimation unit estimating a rotary angle of the coin subject to identification based on the calculated similarity; a correction unit that corrects the line image data based on the estimated rotary angle; and an identification unit that identifies the coin subject to identification based on the corrected line image data.
