Problems solved by technology

The traditional 3D modeling method of substation has obvious disadvantages of heavy workload and low accuracy
Although the 3D laser scanning technology emerging in recent years has solved the problems of data acquisition speed and modeling accuracy, the complicated data processing and purely manual office modeling still require a long cycle

Embodiment Construction

[0048]Below in conjunction with accompanying drawing of description, the present invention will be further described.

[0049] The present invention provides a template library-based substation rapid modeling method, such as figure 1 shown, including the following steps:

[0050] 1) collect data;

[0051] Investigate the substation scene and carry out path planning and site layout, use the 3D laser scanner ScanStationP20 to scan the external structure and internal equipment of the substation, the scanner resolution is 6.3mm@10m, and obtain the substation information point cloud of the external structure and internal equipment of the substation data.

[0052] Among them, the external structure of the substation includes transformers, isolating switches, grounding switches, circuit breakers, grounding arresters, current transformers, voltage transformers, coupling capacitors, fuses, power capacitors and reactors and other structural units or single-unit devices. Form, size an...

Abstract

The invention discloses a template library based rapid modelling method for a transformer substation. The method comprises steps as follows: transformer substation information point cloud data are acquired by a 3D laser scanner; a point cloud model is obtained through data preprocessing; a detailed equipment model represented by CAD models and a 3D landscape model are established through detailed modelling, and a model library is formed through mapping and organization by a management system; overall layout of the transformer substation is established, repeated structure detection is performed, and a mode primary subgraph of the transformer substation is obtained through extraction; on the basis of the established model library, the point cloud model and the corresponding CAD model in the model library are subjected to template fitting with a shape retrieval method, and a CAD model with the maximum similarity to the point cloud model is output; through a registration and calling mode, rapid reestablishment is realized; a 3D overall model of the transformer substation is obtained by fusing the detailed equipment model and the 3D landscape model. The method has the benefits as follows: rapid reestablishment of the transformer substation model is realized, and the modelling efficiency is greatly improved while the model accuracy is guaranteed.
