LegoOcc++ advances open-vocabulary 3D occupancy prediction with novel semantic and geometric methods

Researchers have developed LegoOcc++, a novel framework for open-vocabulary 3D occupancy prediction, particularly addressing challenges in indoor environments. This approach utilizes Language-Embedded Gaussians to link 3D geometry with language-aligned semantics, even with only binary occupancy labels. Key innovations include a Poisson-based Gaussian-to-Occupancy formulation for stable volumetric aggregation and Progressive Temperature Decay for improved semantic learning. The framework also incorporates Instance-Level Semantic Consistency and Covisibility-Aware Support-View Selection to enhance prediction accuracy and reduce supervision redundancy, demonstrating generality across both indoor and outdoor scenarios.
