A simple and flexible smartphone-based 3D navigation solution uses geocoded images that require neither 3D modeling nor real-time rendering of 3D scenes, making it energy-efficient and cost-effective. Real-world images can be also replaced with screen snapshots of the 3D scenes rendered from existing 3D models. Field tests demonstrate energy efficiency, consuming roughly half the power of a model-based solution with real-time rendering of 3D scenes.
