Power transmission line monitoring image defogging method based on Retinex

The invention discloses a power transmission line monitoring image defogging method based on Retinex, and mainly solves the problem that an existing image defogging method cannot effectively improve the quality of a power transmission line monitoring image in foggy days. According to the implementation scheme, the method comprises the following steps: acquiring a foggy day power transmission linemonitoring image, and splitting the image into RGB channel images; performing multi-scale guided filtering on the RGB channel image, and estimating an illumination component; performing weighting to remove the illumination component of the RGB channel image to obtain a restored image; performing histogram equalization on the restored image to obtain an enhanced image; calculating a fusion coefficient, and fusing the restored image and the enhanced image to obtain a fused image; and combining the fused images of the RGB channels to obtain a final defogged image. According to the invention, defogging processing is carri
