Power transmission line target detection method and system under foggy weather condition

The invention discloses a power transmission line target detection method under a foggy day condition. The method comprises the steps of obtaining image data information of a power transmission line under a non-foggy condition and performing data enhancement to obtain image data information of the power transmission line under the foggy day condition; marking image data information of the power transmission line under the foggy weather condition to obtain a training data set; constructing a power transmission line target detection primary model under a foggy weather condition, and training to obtain a power transmission line target detection model; and carrying out power transmission line target detection under the actual foggy weather condition by adopting the obtained power transmission line target detection model. The invention also discloses a system for realizing the power transmission line target detection method under the foggy weather condition. According to the method, fog day data is obtained by enh
