Researchers have introduced VEOcc++, a novel framework for semantic occupancy mapping that integrates both online incremental mapping during exploration and offline refinement for improved scene understanding. This unified voxel-centric approach utilizes a persistent sparse voxel feature map to expand the map with new regions and align local features during exploration, while also enabling multi-scale spatial refinement after exploration using cached features. VEOcc++ has demonstrated state-of-the-art performance on the EmbodiedOcc-ScanNet benchmark, achieving significant improvements in IoU and mIoU for online incremental mapping and further enhancing the completed map through offline refinement. The framework has also shown successful transferability and feasibility for large-scale indoor mapping when deployed on a mobile robot. AI
