Research on construction method of digital twin geometry of power grid station equipment based on feature matching

Inhalt:
At present, the geometric modeling of the digital twin of power grid station equipment is realized by scanning the whole station by exciting radar or UAV oblique photography, and then by manual image segmentation, angle adjustment and material rendering, which has the problems of long time-consuming and high personnel requirements. In order to solve this problem, a digital twin geometry construction method of power grid station equipment based on station mapping based on feature matching is proposed. Firstly, the three-dimensional geometric data of various station equipment are obtained to construct the equipment feature database. Then determine the three-dimensional edge feature information of power equipment in the laser point cloud image of the target station, use the station equipment feature database to match the three-dimensional edge feature information of the target station equipment, and determine the station equipment of the feature database corresponding to the target station equipment. Finally, in the laser point cloud image of the target station equipment, the corresponding digital twin geometry is generated according to the feature database equipment model. This method can quickly realize the construction of digital twin geometry of primary and secondary equipment in power grid stations, and promote the application of digital twin technology in power grid.
