The invention relates to a power transmission tower model construction method and device, computer equipment and a storage medium. The method comprises the steps of obtaining laser radar point cloud data corresponding to a to-be-constructed power transmission tower model, and searching a model template corresponding to the to-be-constructed power transmission tower model according to the laser radar point cloud data; determining model design parameters in a preset model design coordinate system; acquiring structural feature point data of the power transmission tower, and acquiring each to-be-constructed section from a preset section template in a preset model design coordinate system in a matching manner; and connecting the constructed sections to be constructed according to the connectionmode to obtain a power transmission tower model. According to the power transmission tower model construction method, model construction can be completed without inputting all nodes and connecting lines, the power transmission tower model construction efficiency can be fully improved, and normal and safe operation of a power grid is ensured.
