Method for identifying counterfeit coins

The invention discloses a method for identifying counterfeit coins to determining the authenticity of a coin with continuously changing anti-counterfeiting graphs. The method includes the steps of placing coins in a coin inlet track and rolling the coins towards a detection area direction, acquiring surface images of each coin rolled in the detection area by an image acquiring module, generating a plurality continuous coin images for each coin, comparing each coin image with anti-counterfeiting graph images by a determining module where the anti-counterfeiting graph images of the coins are stored in advance to determine whether the coin images have at least two continuously changing anti-counterfeiting graphs with different shapes, if yes, determining the coins to be authentic, otherwise, determining the coins to be counterfeit. 本发明公开了种判断伪造钱币的方法，用于判断具有连续变化防伪图形的钱币的真伪，该方法首先将该钱币放置于进币轨道中，并朝检测区域方向滚动，再利用影像撷取模块滚动于该检测区域内每该钱币的表面影像，并针对每该钱币产生有多个且呈连续的钱币影像。此后，利用预先储存有该钱币的防伪图形影像的判断模块，以该防伪图形影像对每该钱币影像进行比对，判断该些钱币影像中是否存在有至少二连续变
