Latest Patents

Tong Ke holds a patent for "Square root inverse Schmidt-Kalman filters for vision-aided inertial navigation and mapping." This invention involves a vision-aided inertial navigation system that utilizes an image source to produce image data for poses of reference frames along a trajectory. The system includes a motion sensor that provides motion data of the reference frames. A hardware-based processor computes estimates for the position and orientation of the reference frames for the poses. The processor executes a square-root inverse Schmidt-Kalman Filter (SR-ISF)-based estimator to compute constraints that geometrically relate the poses from which respective features were observed. The estimator determines state estimates for position and orientation of reference frames and computes positions of the features observed within the environment. Additionally, it maintains uncertainty data as a square root factor of a Hessian matrix.
