Abstract
This invention relates to the field of streaming 3D reconstruction technology and discloses a spatiotemporally aware key-value cache compression method for streaming 3D reconstruction. The method includes: receiving a continuous stream of image frames, extracting features from each image frame and inputting them into a causal Transformer architecture for inference; maintaining a historical key-value cache during inference and performing spatiotemporally aware cache compression management, specifically including: time-aware short-term cache management, spatially-aware long-term cache management, and block-based multi-frame joint inference. This invention can significantly reduce memory consumption and accelerate the model inference process while ensuring 3D reconstruction quality and temporal consistency, and is suitable for online, real-time, and long-term streaming 3D reconstruction application scenarios.
