Pedestrian Dead Reckoning-Assisted Visual Inertial Odometry Integrity Monitoring. [PDF]
Sensors (Basel), 2019 Visual inertial odometers (VIOs) have received increasing attention in the area of indoor positioning due to the universality and convenience of the camera. However, the visual observation of VIO is more susceptible to the environment, and the error of observation affects the final positioning accuracy.
