摘要
目前国内高压输电线路杆塔三维模型大多依靠专业建模人员参考相应的设计参数,采用CAD软件手工创建,工作量大且费时、费力,难以满足高压输电线路走廊快速数字化建模的需要。对此,提出了一种输电杆塔三维模型组件式建模方法,满足建模人员对输电杆塔的快速、高精度三维重建。通过对不同类型输电杆塔的现有三维模型进行分解,建立输电杆塔的全要素组件模型库,实现模型库中的不同组件能够根据其固定的连接关系自动拼接。在对特定杆塔建模时,用户只需指定输电杆塔的类型和高度参数,并对模型方向和塔头宽度进行微调,即可获得输电杆塔的高精度三维模型。该方法能降低输电线路杆塔三维建模的难度,提高建模效率,满足电力线路走廊快速数字化建模的工程应用需要。
At present, most of 3D models of high-voltage power transmission line towers in domestic rely on professional modelers referring to design parameters and adopting CAD software to build by hand, which means large workload, waste of time and energy and hard to meet requirement of rapid digital modeling for high-voltage power transmission line corridor. Therefore, this paper presents a kind of component modeling method for 3D model of power transmission tower so as to satisfy requirement of modelers for rapid and high-precision 3D reconstruction of the tower. The core of modeling is to decompose current 3D models of different typed power transmission towers, establish all-factor component model bases and realize automatic conjunction of different components according to fixed connected relationship. As modeling for particular towers, the customers only need specify types and height parameters of towers and slightly adjust model direction and tower head width to obtain high-precision 3D models of towers. This method can reduce difficulty of 3D modeling, improve modeling efficiency and meet engineering application requirement of rapid digital modeling for power transmission corridor.
