Multi-dimensional data fusion method and device for digital twin of power transformation equipment

The invention discloses a multi-dimensional data fusion method and device for digital twin bodies of power transformation equipment. The method comprises the following steps: respectively acquiring initial point cloud data and space physical field image data; performing error elimination, point cloud calculation, point cloud filtering and multiple point cloud registration processing on the initial point cloud data to obtain to-be-fused point cloud data; performing preprocessing and image segmentation on the space physical field image data to obtain to-be-fused image data; and fusing the to-be-fused point cloud data and the to-be-fused image data to obtain fused point cloud data. According to the multi-dimensional data fusion method and device for the digital twin of the power transformation equipment provided by the embodiment of the invention, the laser point cloud and the image data are respectively processed and fused, so that precise registration fusion of holographic real-time state data of the twin base
