FreeOcc: The First Training‑Free Open‑Vocabulary 3D Occupancy Mapping System (RSS‑2026)

FreeOcc introduces a training‑free, open‑vocabulary 3D occupancy prediction framework that combines SLAM‑based pose estimation, 3D Gaussian Splatting, and pretrained vision‑language models to build globally consistent semantic maps, achieving over‑two‑fold IoU improvements on EmbodiedOcc‑ScanNet and strong zero‑shot generalization on the new ReplicaOcc benchmark.
