Researchers have developed MIRAGE, a novel system that integrates feed-forward 3D vision with LiDAR-inertial estimation to improve 3D reconstruction quality. MIRAGE anchors visual geometry to precise metric motion from LiDAR-IMU data, while also regulating pose corrections based on correspondence support and cross-modal agreement. This approach enables accurate metric pose estimation and high-fidelity Gaussian reconstruction, outperforming traditional methods like COLMAP on benchmarks such as Oxford Spires and M2DGR. The team also created a new multimodal dataset for evaluating monocular large-scale reconstruction methods in long-horizon indoor scenes. AI
