What is it about?

This paper introduces a new method to improve errors in the Inertial Navigation System (INS) using Unscented Kalman Filter (UKF) by integrating Inertial Measurement Unit (IMU) data with the information provided by the camera, which is based on features' constraints.

Why is it important?

We showed that relative distance between two images is unobservable, but the direction from image one toward two is observable then we implemented the filter in such conditions. For avoiding the increasing dimensions of the covariance matrix, the sequential updating procedure is used in the measurement equation.

Perspectives

I hope this article makes people consider the observability problem in visual navigation systems. It is interesting that we showed using three images don't help us much more for increasing the accuracy of the navigation system.
