StreamVGGT, a causal transformer architecture for real-time streaming 4D visual geometry perception compatiable with LLM-targeted attention mechanism (e.g., FlashAttention), delivers both fast inference and high-quality 4D reconstruction.

Given a sequence of images, unlike offline models that require reprocessing the entire sequence and reconstructing the entire scene upon receiving each new image, our StreamVGGT employs temporal causal attention and leverages cached memory token to support efficient incremental on-the-fly reconstruction, enabling interative and real-time online applitions.
