Abstract: 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.
