Technical Overview of DiDi's AR Indoor Navigation System
DiDi's AR indoor navigation system addresses GPS unreliability in large indoor venues by using SfM-based 3D reconstruction, robust visual localization with magnetometer/GNSS priors, and sensor fusion with pedestrian dead‑reckoning and deep‑learning heading estimation, cutting passenger pick‑up time by up to 25 % across dozens of airports and malls.
