Researchers have introduced LangLoc, a novel three-stage pipeline designed for fine-grained indoor localization using natural language descriptions. This system surpasses previous methods by 8 percentage points in Top-1 recall for scene retrieval, utilizing a dual-branch GATv2 encoder with CLIP semantic features. LangLoc then estimates position and heading with a median error of 0.95 meters by scoring a dense floor grid and resolves remaining ambiguity through a Bayesian dialog module. The project also contributes a benchmark dataset featuring over 13,000 pose-indexed natural-language descriptions across 1,300 indoor 3D scans. AI
