Robust Tightly-Coupled Visual-Inertial Odometry with Pre-built Maps in High Latency Situations

In this paper, we present a novel monocular visual-inertial odometry system with pre-built maps deployed on the remote server, which can robustly run in real-time on a mobile device even in high latency situations. By tightly coupling VIO with geometric priors from pre-built maps, our system can tolerate the high latency and low frequency of global localization service, which is especially suitabl...
