The invention discloses a power transmission line model generation method fusing three-dimensional design and laser point cloud. The method comprises the steps of collecting power grid equipment modeling standards, specifications, model examples and power grid power transmission line general typical design; establishing a three-dimensional design GIM model of the power transmission line; checking the generated three-dimensional design GIM model of the power transmission line, and storing the GIM model into a standard model library after the GIM model is qualified; acquiring laser point cloud data of the power transmission line by using a laser radar technology, and establishing a laser point cloud model of the power transmission line; carrying out differential comparison on the three-dimensional design GIM model of the power transmission line and the laser point cloud model based on the feature points; fusing the three-dimensional design GIM model of the power transmission line and the laser point cloud model to obtain a power transmission line model fusing the three-dimensional design and the laser point cloud; the technical problems that in the prior art, attribute information of power transmission line equipment cannot be truly reflected, a large amount of original design data needs to be inquired in the actual operation and maintenance process, and an operation and maintenance unit cannot be timely and effectively guided to operate and maintain the power transmission line are solved.

Description

technical field [0001] The invention belongs to transmission line model generation technology, in particular to a transmission line model generation method that integrates three-dimensional design and laser point cloud. Background technique [0002] Three-dimensional laser scanning has been widely used in many major projects and typical fields. In the field of high-voltage transmission line operation and maintenance, due to the complex geographical environment of the region, traditional manual inspection methods are difficult to adapt; airborne three-dimensional laser scanning can directly obtain power line The geometric parameters of its auxiliary equipment provide a new means for power inspection; in the existing technology, the operation and maintenance unit has established a complete lidar scanning system for overhead transmission lines, and has mastered a large number of lidar data for power grid projects. Laser point cloud data can automatically and quickly build a 3D ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a method for generating a transmission line model that integrates three-dimensional design and laser point cloud, so as to solve the existing problem of using laser point cloud to construct a three-dimensional model of a transmission line to guide the operation and maintenance of a transmission line in the prior art: The grasp of various information of the project is not comprehensive enough to truly reflect the attribute information of the transmission line equipment. In the actual operation and maintenance process, a large amount of original design data needs to be queried, and technical issues such as the operation and maintenance of the transmission line cannot be guided effectively by the operation and maintenance unit in a timely manner.
