Sequential Fusion of Multi-view Video Frames for 3D Scene Generation

3D scene understanding and generation are to reconstruct the layout of the scene and each object from an RGB image, estimate its semantic type in 3D space and generate a 3D scene. At present, the 3D scene generation algorithm based on deep learning mainly recovers the 3D scene from a single image. Due to the complexity of the real environment, the information provided by a single image is limited, and there are problems such as the lack of single-view information and the occlusion of objects in the scene. In response to the above problems, we propose a 3D scene generation framework SGMT, which realizes multi-view position information fusion and reconstructs the 3D scene from multi-view video time series data to compensate for the missing object position in existing methods. We demonstrated the effectiveness of multi-view scene generation of SGMT on the UrbanScene3D and SUNRGBD dataset and studied the influence of SGCN and joint fine-tuning. In addition, we further explored the transfer ability of the SGMT between datasets and discussed future improvements.
