摘要
将轴心轨迹x轴与y轴的信号联系起来形成极径函数.基于此函数的小波变换零交叉表示和匹配过程,得到了识别轴心轨迹的一种新方法.
The x axis and y axis signals of the orbits of shaft centerline to form a radial function are combined. Based on zero crossing representation of wavelet transform of this radial function and matching procedure, a new algorithm to identify orbits of shaft centerline is proposed. Experimental results show that the algorithm can efficiently provide a higher resolution.
