Hierarchical and Holistic Open-Vocabulary Functional 3D Scene Graphs for Indoor Spaces
Two new research papers introduce novel frameworks for generating open-vocabulary 3D scene graphs. The first, RelWitness, addresses incomplete supervision by using visual-geometric cues to verify relations between objects. The second, a hierarchical and holistic approach, anchors functional edges from 2D visual evidence and optimizes them through temporal graph processing for indoor spaces. Both methods aim to improve the accuracy and completeness of 3D scene understanding for applications in robotics and scene analysis. AI
