Abstract

The invention discloses a three-dimensional modeling method and device for a transformer substation. The method comprises the following steps: determining a preliminary three-dimensional model of a transformer substation according to high-altitude measurement data acquired by an aerial flight route of an unmanned aerial vehicle at a high altitude; wherein the high-altitude measurement data comprise multi-angle oblique photography information of the substation equipment; planning a flight route of the unmanned aerial vehicle at a low altitude according to the preliminary three-dimensional model; wherein the distance from the low altitude to the ground is smaller than that from the high altitude to the ground; and forming a three-dimensional model of the transformer substation according to the low-altitude measurement data and the high-altitude measurement data obtained by the flight route of the unmanned aerial vehicle at the low altitude. The safety of the unmanned aerial vehicle during low-altitude flight can be guaranteed, the requirement for the driving technology of an unmanned aerial vehicle driver is lowered, the operation difficulty is simplified, and the labor cost is lowered. And meanwhile, the precision of the three-dimensional model of the transformer substation can be further improved on the basis of the preliminary three-dimensional model, and when the three-dimensional model of the transformer substation is subsequently applied, the use of various functions of the model can be effectively supported.

Description

technical field

[0001] Embodiments of the present invention relate to the technical field of power grids, in particular to a three-dimensional modeling method and device for a substation. Background technique

[0002] With the promotion of digital transformation work of power grid companies such as "Digital China" and "Digital Grid", digital twin substations have been more and more widely recognized from the proposal, construction to application. The digital twin substation means that the substation is digitally modeled to form a digital model that is exactly the same as the real object. Among the many technical routes to achieve this goal, the method of generating a 3D real-scene model of a substation using oblique photographic aerial survey technology and aeronautical triangulation calculation algorithms, compared with other technical solutions (such as 3D design, laser point cloud acquisition and generation etc.), it has many advantages such as high degree of reduction, ...
