一种货币识别传感器有效性与精度分析方法

A Method of Validity and Precision for Sensor Analyses in Currency Recognition

货币识别技术利用各种传感器来检测和测量货币的各类信息,选择有效、精确的传感器是实现货币识别的第一步工作;在真币性质比较稳定,以及货币样本容易获取的现实条件下,讨论了真币性质的特性,提出了基于正态分布和向量范数的检测方法,它通过对货币样本数据的统计分析来判断传感器的有效性和精确性;此方法简洁实用,为传感器的选择提供了客观依据。

All kinds of the techniques of currency recognition utilize the sensors to obtain the information of the currency.So,it is first step to select the effective and precise sensors used on the mechanism of currency recognition.Because the characters of the real currency are stable and the currency samples are gained easily,the rule of the characters of the real currency is discussed.The method is based on the theory of normal distribution and norm is proposed,it can examine the validity and precision of sensors by analyzing the data of currency sample.This method which offered impersonal criterion to select appropriate sensors is easy to use.
