【摘要】 文章通过单片机处理由传感器采集到的票据的光谱信号,通过对票据碾钞过程的数学模型分析,利用倾斜票据的计算几何的等比例性质,采用多项式逼近、Pade逼近、最小二乘逼近和非线性优化算法研究出一个代数公式,该代数公式能精确逼近碾钞过程中发生倾斜的纸币宽度值。更多还原

【Abstract】 This paper will deal with the bills’ spectrum signals which gather from the sensor by singlechip.By analyzing the mathematical model of bills’ verifying processes,using the geometric proportion property of calculational geometry on bills’ incline,and the polynomial approaches,Pade approaches,the smallest two multiplication approaches and nonlinear optimized algorithms,we obtain an algebraic formula,which can precisely approach the width value of bills that produce an incline when we verify them.更多还原
