摘要
随着二维GIS系统在电力行业应用的不断深入,其在对空间位置及周边地形的描述上遇到了一定的局限性。电力系统对输电线路三维展示的需求变得急迫,而为了在三维场景中快速生成符合实际线路台账的输电线路,形成三维电网结构,在此提出一种半自动的三维输电线路构建算法。该算法包括了三维建模规则、坐标转换、线路生成等步骤,可以为当前三维场景中输电线路的架设提供技术参考,此算法模型可复用、开放性、自由度高,具有广泛的应用前景。
With the application deepening of two-dimensional GIS system in electric power industry,the description of spatial position and the surrounding topography is limited,and the demands for three- dimensional（3D） display of transmission lines in electric power system have become urgent. To quickly generate transmission lines corresponding to the actual line information in 3D scene to form 3D grid structure,a semi-automatic construction algorithm of 3D power transmission line is proposed. The algorithm includes 3D modeling rules,coordinate transformation,line generation and other steps,which can provide technical reference for erection of transmission line in current 3D scene. This algorithm is reusable,and has good open,high free degree and wide application prospect.
