ImprovedVBGS: Real-time Continual Variational Bayes Gaussian Splatting
Quick Answer
This paper shows that ImprovedVBGS accelerates real-time continual 3D reconstruction, achieving a 1680x speed-up in latency from ~84.0s to ~0.050s on RTX 3070 Ti, while maintaining reconstruction quality.
Quick Take
This framework enhances Variational Bayes Gaussian Splatting through spatially truncated inference and improved reassignment techniques, making it suitable for robotics and autonomous navigation applications.

Source Excerpt
On-the-fly reconstruction is a key requirement for many applications in robotics and autonomous navigation. Variational Bayes Gaussian Splatting (VBGS) enables continual learning without replay buffers using Coordinate Ascent Variational Inference (CAVI), but its per-frame iterations over all observed points make it too slow for real-time use with strict memory and latency requirements. We present ImprovedVBGS, an accelerated framework for on-the-fly continual reconstruction. This is achieved pr
