摘要
针对输电线路设备三维模型数据海量,在三维数字地球中加载卡顿的问题,提出基于LOD技术的输电线路设备三维模型构建方法。该方法充分研究设备自身特点,提出构建模型的简化原则,在此基础上,构建模型LOD,将模型划分为4个等级,并提出各级模型塌陷方法。最后开展模型测试以及应用,结果表明:在目前市面上标准配置的PC机上,利用三维数字地球展示平台加载4级LOD模型,加载显示流畅,可满足输电线路设备三维仿真的需求。
In view of the large amount of data of three dimensional model of transmission line equipment and the problem of loading Caton in three dimensional digital earth,a three dimensional model construction method of transmission line equipment based on LOD technology is proposed.This method fully studied the characteristics of the equipment itself and proposed the simplified principle of building the model.On this basis,the model LOD was built,the model was divided into four levels,and the model collapse method was proposed.Finally,the model test and application were carried out.The results showed that the 4 D LOD model was loaded on the standard PC in the market and the 3D digital earth display platform was used to load the LOD model.The load display was smooth and could meet the needs of 3D simulation of transmission line equipment.
