在考古工作中,古钱币是一种常见的出土文物,数量大、品种多。通过对古钱币的研究可以了解当时的政治、财经以及冶炼技术的情况。但是许多古钱币由于年代久远,表面的铸文已被锈蚀得模糊不清,有时虽尚能隐约可见铸文的痕迹,但已无法用人眼来直接辨认了。这样势必造成无法通过表面的铸文来直接确认其铸造的年代。虽然可以通过对它的成分分析来判断其铸造年代,但毕竟还是一种间接的判定方法。如果对古钱币表面的铸文通过图象处理技术来加以复现,并通过分析其内含成分的方法来加以证实的话,那么就可以可靠而直观地断定其铸造的
In archeology, ancient coins is a common unearthed artifacts, a large number of varieties. Through the study of ancient coins can understand the political, financial and smelting technology. However, many ancient coins as a result of the passage of time, the surface of the cast has been blown rust blurred, sometimes still can vaguely visible traces of cast, but can not be directly identified with the human eye. This will inevitably lead to the surface can not be cast to directly confirm the casting of the era. Although its component analysis can be used to judge its casting age, it is still an indirect method of determination. If casts of the surface of ancient coins are reproduced by means of image processing techniques and verified by means of analysis of their contents, it can be reliably and intuitively concluded that the cast
