Method and system for identifying fast-growing tree species of power transmission line channel

The invention discloses a method and a system for identifying fast-growing tree species of a transmission line channel. The method specifically comprises the following steps of: identifying the position of a tower in a panoramic puzzle by using a rotating target detection algorithm; delimiting a power transmission line buffer area according to the position of the tower; identifying fast-growing tree species in the power transmission line buffer area by using semantic segmentation; according to the method, on the basis of the power transmission line channel unmanned aerial vehicle routing inspection panoramic puzzle, the position of the tower is obtained through the rotating target detection algorithm by adopting the optimized OrientidR-CNN model, aiming at the characteristics that the fast-growing forest is uncertain in size and shape and relatively simple in feature, the existing UpNet model is optimized, and the fast-growing tree species are distributed in a spatial data open format. Therefore, the fast-gro
