摘要： A fast fingerprint searching method and fast fingerprint searching system are provided. Fingerprint templates in the fingerprint template library are classified into templates with core points and templates without core points. The fast fingerprint searching method involves: collecting the fingerprint templates needed to be compared and finishing the extraction of on-site fingerprint features; judging that the extracted on-site fingerprint features are on-site fingerprint features with core points or on-site fingerprint features without core points; respectively comparing the on-site fingerprint features with all the templates with core points in the fingerprint template library if they are on-site fingerprint features with core points; respectively comparing the on-site fingerprint features with all the templates without core points in the fingerprint template library if they are on-site fingerprint features without core points.

摘要翻译： 提供快速指纹检索方法和快速指纹检索系统。 指纹模板库中的指纹模板分为具有核心点和模板的模板，无核心点。 快速指纹搜索方法包括：收集需要比较的指纹模板并完成现场指纹特征的提取; 判断提取的现场指纹特征是具有核心点的现场指纹特征或没有核心点的现场指纹特征; 分别将现场指纹特征与所有模板与指纹模板库中的核心点进行比较，如果它们是具有核心点的现场指纹特征; 分别将现场指纹特征与指纹模板库中没有核心点的所有模板进行比较，如果它们是没有核心点的现场指纹特征。
