Abstract
Fault detection for real-time visual-inertial odometry motion tracking. A fault detection system allows immediate detection of error when the motion of a device cannot be accurately determined. The system includes subdetectors that operate independently and in parallel to a main system on a device to determine if a condition exists which results in a main system error. Each subdetector covers a phase of a six-degrees of freedom (6DOF) estimation. If any of the subdetectors detect an error, a fault is output to the main system to indicate a motion tracking failure.
