Tower suspension point tension inversion method based on airborne laser point cloud

The invention relates to the technical field of power transmission line tension inversion, in particular to a tower suspension point tension inversion method based on airborne laser point cloud, and the method comprises the steps: obtaining a first suspension point and a second suspension point of an overhead transmission line, and constructing a suspension arc curve space model of the overhead transmission line according to moment balance; acquiring airborne laser point cloud of the overhead transmission line, determining a three-dimensional spatial form of the transmission line according to the spatial relationship, and reconstructing a spatial model of the transmission line by using the discrete airborne laser point cloud; and executing suspension point tension inversion according to the suspension arc curve space model and the power transmission line space model to obtain the suspension point axial tension of the overhead power transmission line. According to the method, a power transmission line model pa
