Intelligent modeling method for three dimensional reconstruction of monocular visual motion structure in substation

Through the reconstruction and processing of substation point cloud data, the fusion of 3D spatial positioning and BIM modeling, and the optimization of 3D visualization closed-loop path of the model, an intelligent modeling method is proposed. Experimental results show that, compared with the traditional modeling method, the proposed intelligent modeling method can achieve the measurement accuracy of SFM motion structure in large scene of substation less than 0.5mm, and the BIM model integrated with 3D point cloud is more perfect in digitalization, which can realize the high-precision modeling of substation.
