WebJan 11, 2024 · Download PDF Abstract: We present DM-VIO, a monocular visual-inertial odometry system based on two novel techniques called delayed marginalization and pose graph bundle adjustment. DM-VIO performs photometric bundle adjustment with a dynamic weight for visual residuals. We adopt marginalization, which is a popular strategy to keep … WebThe key component of the proposed system is an improved bundle adjustment module containing multiple sampling, initialization of ego-motion, dynamic damping factor adjustment, and Jacobi matrix weighting. In addition, a novel relative photometric loss function is advanced to improve the depth estimation accuracy.
