Description

Technical Field

[0001] The present invention relates to the field of power construction planning and design, and in particular to a method for generating an electric tower erection plan based on an unmanned aerial vehicle (UAV). Background Art

[0002] Since many power line project routes are often located far from residential areas, they often run through remote, mountainous, and densely forested areas. Minimizing impacts on the human environment while avoiding significant increases in project costs and time due to land acquisition and relocation creates real challenges, such as complex terrain and challenging survey and design. Traditional transmission line survey methods would require extensive clearing of pathways, which is neither environmentally friendly nor efficient, and does not meet government regulations for addressing the "whitewashed mountains" problem. Furthermore, due to the non-aerial survey approach, route plans must be finalized only after obtaining on-site measurement data, resulting in high on-site labor intensity and low efficiency. These established route plans lack a holistic and integrated approach, and as the line progresses, new obstacles often disrupt previously selected options. This ultimately leads to significant duplication of work, limited efficiency gains, and delayed project completion. Therefore, the use of aerial surveys to assist in the survey and design of power line projects has become a growing trend.

[0003] With recent advances in drone aerial photography technology, drones are increasingly being used to capture image data in surveying and mapping projects. Drones are compact, maneuverable, efficient, and low-cost, offering significant advantages for quickly acquiring high-resolution imagery in small areas and difficult-to-fly areas. However, due to the difficulty and significant impact of topography on the erection of power towers, their safety and stability, along with the impact of topography, make it difficult for engineers to factor these factors into their overall design. Furthermore, existing experience makes it difficult to assess the disaster resistance of power towers. Consequently, the construction of power towers is long and expensive. Furthermore, the long construction period and the large number of components involved make it difficult for construction engineers to estimate the required component list. Therefore, accurate planning and layout during the initial phase of tower construction are crucial for ensuring the ease and cost-effectiveness of subsequent on-site construction. Summary of the Invention

[0004] The purpose of the present invention is to propose a method for generating a tower erection plan based on a drone.
