摘　　要：鉴于目前市面上流行的硬币计数器在硬币的鉴伪方面存在着种种问题,提出了一种基于图案检测的原理对硬币进行鉴伪的方法,具体介绍了系统的硬件组成和工作原理。使用该设备可以方便地对国产的12种硬币进行鉴伪,准确度可达99.99%,整机效率可达8枚/s,样机的研制成功充分表明了该技术的可行性。Considering the problems of the recognizing the true coin by the popular coin counters, a system for distinguishing the coin based on image detecting was presented, and system structure and principle were introduced. Through the equipment, the twelve internal coins can be judged, the accuracy is 99. 99%, and the efficiency is 8 pieces per second. The sample machine shows the technique is feasible.
