This invention provides a method for assessing the weight of ice accretion on power transmission lines based on multi-source data fusion and 3D reconstruction technology. By deploying image acquisition devices at four shooting positions on the target section of the transmission line and acquiring environmental parameters, the current ice accretion type can be accurately identified, and the corresponding ice density can be determined. Furthermore, based on the image data from the four shooting positions, the overall structure of the transmission line and ice accretion is reconstructed in 3D, thereby accurately determining the overall volume of the ice accretion on the target section. This reduces the error in volume assessment caused by the irregular shape of the ice accretion, thus accurately determining the ice volume of the target section. Finally, the accurate overall ice accretion mass and ice accretion mass per unit length of the target section are calculated, providing accurate data support for subsequent ice condition warnings, ice melting decisions, and line condition maintenance.
