Abstract

The invention discloses a coin identification instrument and a coin identification method. The coin identification instrument comprises a bearing part for bearing a coin, a side light source for illuminating the coin from a non-vertical direction, and a camera for collecting an image. The bearing part is made of a light-transmitting material, and the coin identification instrument also comprises a reflector. The reflector is used for reflecting the front image and the back image of the coin to the camera, and the coin identification method uses the coin identification instrument to collect the image of the coin under side light and compare the image with a reference image. According to the coin identification instrument and the coin identification method, the depth difference of an embossment is presented on a picture through the change of the light source angle so that the identification of the coin is more accurate.
