HIGS: Hierarchical Implicit Grids for Joint Geometric and Semantic Scene Understanding
Neural implicit representations have had a significant impact on scene reconstruction by enabling robots to build continuous, differentiable, and high-fidelity 3D maps. Most existing works focus on geometric reconstruction and lack semantic information for high-level spatial understanding and task planning. Also, as th...
