M2C-GVIO: motion manifold constraint aided GNSS-visual-inertial odometry for ground vehicles
Abstract Visual-Inertial Odometry (VIO) has been developed from Simultaneous Localization and Mapping (SLAM) as a low-cost and versatile sensor fusion approach and attracted increasing attention in ground vehicle positioning.However, VIOs usually have the degraded performance in challenging environments and degenerated motion scenarios.In this pape
