New sparse topometric graph slashes memory needs for indoor navigation

Researchers have developed a sparse topometric graph representation for indoor navigation that significantly reduces computational and memory requirements compared to traditional point-level map representations. This method uses nodes encoding local 3D geometry and weighted edges capturing traversable connectivity, enabling robust cross-session navigation even with scene changes or different sensor modalities. Experiments demonstrated high success rates on the Gibson and 3D-FRONT datasets, with memory usage reduced by over two orders of magnitude. AI

IMPACT This approach could enable more efficient and scalable indoor navigation systems by reducing computational overhead.

    A Sparse Topometric Graph for Scalable Cross-Session Indoor Navigation

    arXiv:2610.31432v1 Announce Type: cross Abstract: A conventional embodied agent in an indoor environment builds a map by accumulating noisy real-world measurements and results from heavy inference to guide navigation. While the detailed measurements may differ due to scene change…
