Research on data processing technology of substation 3D modeling based on distributed fast storage

针对三维重建的技术在单一数据源的建模方面适用范围较窄且无法处理复杂应用场景等问题,文中根据三维模型信息与模型复用关系,并结合分布式快速存储技术来建立设备模型。将贴图数组赋值给场景光照贴图属性,从而生成了还原光照的设备模型。实际案例使用结果表明,文中所提出的数据处理技术能够有效降低模型所占内存大小,节约了加载模型的时间。与其他分布式算法相比,文中算法能够兼顾更新成本与响应速度,并提高数据加载效率,从而更有利于模型的快速渲染和存储。

The technology for 3D reconstruction has a narrow scope of application in the modeling of single data source,and can not deal with the problem of complex application scenarios. According to the relationship between 3D model information and model reuse,combined with distributed fast storage technology,a device model is established. Then,the map array is assigned to the scene lighting map attribute,and the device model with restored lighting is generated. The actual case results show that the data processing technology proposed in this paper can effectively reduce the memory occupied by the model and save the time of loading the model. Compared with other distributed algorithms,this algorithm can take into account the update cost and response speed,improve the data loading efficiency,and is conducive to the rapid rendering and storage of the model.
