Researchers have developed a new method called CELL for improving event-camera localization in LiDAR maps. This technique learns to assign confidence scores to correspondences between event images and LiDAR depth views, addressing a bias where correspondences at greater depths are less informative for pose estimation. By using a differentiable probabilistic PnP solver, CELL learns these confidences end-to-end, which are then used to reweight supervision during training and refine pose estimation at test time. The CELL system demonstrated improvements on the M3ED and DSEC datasets, reducing median translation error by up to 26.9% and median rotation error by up to 15.8% compared to the LEAR baseline. AI
