Researchers have developed a new multi-modal framework called LTM (Large-scale Terrain Model) that uses outdated Digital Elevation Models (DEMs) as geometric priors for image-based 3D reconstruction. This approach significantly reduces computational complexity by employing physics-based pixel-pixel alignment, eliminating the need for expensive feature matching. The method achieves real-time performance and produces high-fidelity depth maps, offering a scalable solution for creating accurate 3D terrain maps in wildfire-prone areas where conventional methods struggle.
