Gaoya dianqi, 2017 为了有效检测弹簧机构高压断路器的运行状态,文中从高压断路器分合闸线圈的典型电流波形出发,提出了一种基于样条插值和多尺度线性拟合的电流信号特征提取方法。该方法将电流波形极值点对应的时间和电流大小作为特征,首先使用三次样条插值对电流波形进行平滑,然后将信号按设定的较大长度分为若干段,对每一段进行最小二乘拟合,根据每一段信号的趋势,定位极值点的大致位置,在极值点的大致区间内,缩小尺度进行拟合,重复这个过程至极值点所在区间足够小,在此区间寻找极大值点或极小值点,作为信号的特征点 ...

Dianci bileiqi, 2020 针对使用机器视觉技术对接触网绝缘子状态检测时的绝缘子识别问题,提出一种结合Canny边缘特征和SURF点特征的绝缘子识别算法。该算法首先提取图像边缘特征,然后使用SURF算法在边缘图像上提取特征点,并利用Haar小波对特征点进行描述;对检测出的特征点使用欧氏距离比值法进行初匹配;最后用RANSAC算法消除由噪声等干扰产生的错误匹配,从而实现接触网绝缘子智能识别。实验结果表明,该算法能在有背景干扰、小幅度旋转的目标图像中准确识别出绝缘子,为电气化铁路接触网绝缘子智能清洗的视觉识别定位问题提供了可行参考。
