摘　　要：电力设备故障会导致停电事故,影响电网的安全稳定运行。根据电力设备运行时会产生热量的特点,提出一种电力设备的红外与可见光图像配准方法,便于进行异常发热故障检测。首先通过Sobel边缘检测算子提取电力设备的红外与可见光图像的边缘信息,得到边缘图像;然后通过SuperPoint算法检测2幅边缘图像的特征点并计算描述子,利用SuperGlue算法对特征点进行匹配;最后通过最小二乘法计算仿射变换模型参数,实现电力设备的红外与可见光图像配准。实验结果表明本文方法能够对电力设备的红外与可见光图像进行高精度的配准。The failure of power equipment may cause power outages and affect the safe and stable operation of power grid.According to the characteristics of heat generated by power equipment during operation,an infrared and visible images registration method for power equipment is proposed to facilitate detection of abnormal heating faults.Firstly,the Sobel edge detection operator extracts edge information from infrared and visible images of power equipment to obtain edge images.Then the feature points of two edge images are detected by the SuperPoint algorithm and the descriptors are calculated,and the feature points are matched by the SuperGlue algorithm.Finally,the affine transformation model parameters are calculated by the least square method to realize the infrared and visible image registration of power equipment.The experimental results show that the method in this paper can achieve high-precision registration of infrared and visible images of power equipment.
