摘　　要：针对当前电力设备的海量状态监测多源异构数据无法自动化合成与立体展示的问题,提出了全自动化的电力设备多源异构数据空间合成与立体展示方法。首先利用单目可见光三维重建方法从电力设备可见光图像中恢复设备空间信息以及精细三维网格模型;再使用同源、异源图像配准方法分别建立同源、异源状态数据之间的空间关联关系,并使用提出的数据决策方法建立状态数据间一对一的匹配关系;紧接着以三维网格模型为基础,赋予该模型已配准的多源异构数据可视化纹理,完成设备状态数据的空间合成与立体展示;最后对输变电设备状态数据进行空间合成与立体展示试验,试验结果验证了该方法的适用性和有效性。Aiming at the problem that the current large amount of multi-source heterogeneous data of power equipment condition monitoring cannot be automatically synthesized and stereoscopically displayed,a fully automatic method for multi-source heterogeneous data spatial synthesis and stereoscopic display of power equipment is proposed.Firstly,the monocular visible 3D reconstruction method is used to recover the spatial information and the fine 3D mesh model of the equipment from the visible images.Then,the spatial relationships between the homologous and heterogeneous state data are established by utilizing the homologous and heterogeneous image registration methods,respectively,and the one-to-one matching relationship between the state data is established by utilizing the proposed data decision method.Furthermore,the grid model is regarded as the basis and textured with the registered multi-source heterogeneous data to complete the spatial synthesis and three-dimensional display task of the equipment state data.Eventually,the experiment of spatial synthesis and stereoscopic display of the equipment state data is established.The results verify the applicability and effectiveness of the proposed method.
