A new method called COLMAP-Free 3D Gaussian Splatting (CF-3DGS) has been introduced by researchers from UC San Diego, NVIDIA, and UC Berkeley. It synthesizes views using video’s temporal continuity and explicit point cloud representation without the need for Structure-from-Motion (SfM) preprocessing. CF-3DGS optimizes camera pose and 3DGS jointly, making it suitable for video streams or ordered image collections. It demonstrates robustness in pose estimation and view synthesis quality.

Novel View Synthesis with COLMAP-Free 3D Gaussian Splatting (CF3DGS)
The progress in neural rendering has led to significant breakthroughs in reconstructing scenes and generating new viewpoints. However, the effectiveness of these methods often relies on precise pre-computation of camera poses, presenting a challenge for practical implementation.
Practical Solutions and Value
Researchers have introduced COLMAP-Free 3D Gaussian Splatting (CF-3DGS) to address these challenges. This approach enhances temporal continuity from video and the explicit point cloud representation, enabling the real-time rendering of views with a pure explicit representation and a differential point-based splatting method. CF-3DGS optimizes the 3D Gaussian Splatting and camera poses simultaneously, achieving rapid training and inference speeds.
The CF-3DGS method delivers robustness in pose estimation and superior quality in novel view synthesis compared to previous state-of-the-art methods. It has been validated on complex and challenging camera movements, outperforming existing methods and demonstrating its accuracy in estimating camera poses, especially in scenarios with complex camera movements.
In conclusion, CF-3DGS is a method that effectively and robustly synthesizes views using video’s temporal continuity and explicit point cloud representation without the need for Structure-from-Motion (SfM) preprocessing. It optimizes camera pose and 3DGS jointly, making it suitable primarily for video streams or ordered image collections. It offers potential for future extensions to accommodate unordered image collections.
