摘　　要：介绍了贵金属首饰检测中,可用于贵金属首饰印记智能识别算法中,字符组合模板制作的材料纯度等印记的常见字符组合形式。对贵金属首饰中最常见的金首饰、银首饰、铂首饰、钯首饰以及含金覆盖层首饰的中文字符、英文字符和数字字符印记进行了归纳。建议使用两种方法扩大字符组合模板库的规模,以增强实际印记识别时的匹配性。The intelligent Assistant recognition system for precious metal jewelry imprint mainly uses image capture equipment and character recognition algorithm to detect and identify the imprint of precious metal jewelry,which will greatly alleviate eye fatigue of jewelry testers.And it can also be used for the automatic generation of precious metal detection reports.Precious metal jewelry imprint intelligent recognition system based on template matching can use imprint characters combination templates to increase the speed of identifying imprint characters in jewelry images taken by an image capture equipment.This paper summarizes the common characters combination forms of the material and purity imprint encountered in author’s precious metal detection work in many years that can be used in making characters combination templates.
