基于图像识别技术的古钱币真伪鉴别初探——以清代铜钱为例

A Preliminary Study on Authenticity Identification of Ancient Coins Based on Image Recognition Technology — Taking Qing Dynasty Copper Coins as an Example

摘要

古钱币是历史文化的重要载体，清代铜钱因存世量大、仿品繁多，给真伪鉴别带来挑战。本文以60枚清代铜钱（真品30枚、仿品30枚）为研究样本，初探基于Excel实现简易图像识别技术的真伪鉴别路径。通过采集样本图像并预处理，提取文字、纹饰、包浆核心特征，利用Excel进行特征量化与数据分析，构建简易鉴别模型。研究表明，该方法能有效捕捉古钱币真伪特征，鉴别准确率较高，且工具易获取、操作简便，适合初级收藏爱好者与学生群体应用。

Abstract

Ancient coins are important carriers of historical and culture. Qing Dynasty copper coins bring challenges to authenticity identification due to their large quantity in existence and a great number of counterfeits. Taking 60 Qing Dynasty copper coins (30 genuine ones and 30 counterfeit ones) as research samples, this paper initially explores the path of authenticity identification of simple image recognition technology realized by Excel. By collecting and preprocessing sample images, extracting the core features of characters, decorative patterns and patina, quantifying features and conducting data analysis with Excel, a simple identification model is constructed. The research results show that this method can effectively capture the authenticity features of ancient coins with a relatively high identification accuracy. In addition, the tool is easily accessible and simple to operate, which is suitable for primary collectors and student groups to use.
