摘　　要：采用目前算法确认隔离开关的位置时,未对采集的图像进行相关预处理,导致算法存在时间复杂度高、定位误差大和定位检测率方差大的问题。提出应用于程序化操作的隔离开关位置自动确认算法,考虑连续函数的基础上,采用直方图均衡法对图像进行均衡处理,采用灰度变换方法,根据灰度直方图对隔离开关图像进行灰度拉伸变换,利用脊回归问题描述隔离开关位置的自动确认问题,采用目标样本的循环位移,通过二维高斯函数获取隔离开关图像对应的标签,并采用核相关滤波方法实现隔离开关位置的自动确认。实验结果表明,所提算法的时间复杂度低、定位误差小、定位检测率方差小。When the current algorithm is used to confirm the position of the isolating switch,the collected images are not preprocessed,which leads to the problems of high time complexity,large positioning error,and large variance of the positioning detection rate.An automatic disconnector position confirmation algorithm applied to programmed operation is proposed.On the basis of considering the continuous function,the histogram equalization method is used to balance the image,the gray transformation method is used to stretch the disconnector image according to the gray histogram,and the ridge regression problem is used to describe the automatic disconnector position confirmation problem,Using the cyclic displacement of the target sample,the label corresponding to the disconnector image is obtained by two-dimensional Gaussian function,and the automatic confirmation of the disconnector position is realized by kernel correlation filtering method.Experimental results show that the proposed algorithm has low time complexity,small positioning error,and small variance of positioning detection rate.
