提出了一种用于识别竹节纱外观参数的启发式方法。利用电容传感器和数据采集卡对竹节纱信号进行采集。然后基于一种新的基于局部最小幅度的方法将竹节纱信号分离成几个短的部分。对于每个短节，计算一个自适应阈值，并进一步采用该阈值来识别粗节。与全局阈值相比，局部自适应阈值减少了不均匀的负面影响。实验结果表明，该方法具有较好的效果。
A heuristic approach was presented in this paper to identify the appearance parameters of slub yarn. The signal of slub yarn was firstly acquired with a capacitance sensor and a DAQ (Data AcQuisition) card. The slub yarn signal was then separated into some short parts based on a new local minimal amplitude based method. For each short part, an adaptive threshold was calculated and further adopted to identify the slub parts. Comparing with the global threshold, the local adaptive threshold reduces the negative affection of unevenness. Experimental results show that the presented approach works well.
