| Abstract:Research on the visual monitoring of the vulnerability of high-voltage electrical equipment in substations based on video superposition algorithm, improve the richness of electrical equipment details, and enhance the visual effect of the vulnerability of high-voltage electrical equipment in substations. Using the improved α-mixing algorithm combined with the anti-aliasing of the video background color, the visible light video and infrared video of the high-voltage electrical equipment in the substation are superimposed. The guide filter is selected to divide the superimposed visible light and infrared video frames into the basic layer and the detail layer. Adaptive weighted two-dimensional principal component analysis (W2DPCA) fuse visible light frame and infrared frame base layer, select the visible light frame detail layer as the final detail layer, combine the base layer and detail layer after fusion to obtain the final fusion frame, and use the final fusion frame to achieve high voltage in the substation Visual monitoring of the vulnerability of electrical equipment. The experimental results show that the visual monitoring of the vulnerability of high-voltage electrical equipment in substations obtained by this method can reflect the rich details of high-voltage electrical equipment in substations, and the texture color and edge contrast of equipment have been strengthened, which is convenient for accurately judging the vulnerability of high-voltage electrical equipment in substations. |
