Abstract

The invention relates to a power transmission line tower based on a laser point cloud total-factor model library and an implementation method thereof, and the method comprises the following steps: collecting the laser point cloud data of the power transmission line tower, and building a tower laser point cloud assembly model library; establishing a tower three-dimensional model according to the tower laser point cloud assembly model library, a to-be-established power transmission line tower and the position information of the to-be-established power transmission line tower; and constructing apower transmission line tower according to the tower three-dimensional model. The realization method of the transmission line tower is suitable for any power transmission line, modeling can be completed without professionals, the high precision of a traditional laser scanning modeling method is reserved, meanwhile, the process of repeated data collection and repeated processing is reduced, the cost input of power transmission line tower modeling is reduced, and the efficiency of power transmission line tower three-dimensional modeling is improved on the whole; the tower three-dimensional modelis fine in representation and high in model precision, and cannot be distorted due to influences of equipment, atmospheric environment and the like.

Description

technical field [0001] This application relates to the field of transmission line construction, in particular to a transmission line tower based on a laser point cloud full-element model library and its implementation method. Background technique [0002] In recent years, with the rapid development of my country's economy, the demand for electric energy in all walks of life has continued to increase, the scale of the power grid has continued to expand, and the requirements for standardized and lean management of lines have become higher and higher. Generally speaking, the distance of overhead transmission lines is long, and the corridor environment is complex and diverse, which is closely related to the geographical space position, especially the level information in the vertical direction is particularly important. However, the operation and maintenance management method based on two-dimensional visual effects has certain limitations in spatial expression and analysis capab...
