Handling Delayed Fusion in Vision-Augmented Inertial Navigation

Ehsan Asadi, Carlo L. Bottasso

Abstract

In this paper we consider the effects of delay caused by real-time image acquisition and feature tracking in a previously documented Vision-Augmented Inertial Navigation System. At first, the paper illustrates how delay caused by image processing, if not explicitly taken into account, can lead to appreciable performance degradation of the estimator. Next, three different existing methods of delayed fusion are considered and compared. Simulations and Monte Carlo analyses are used to assess the estimation error and computational effort of the various methods. Finally, a best performing formulation is identified, that properly handles the fusion of delayed measurements in the estimator without increasing the time burden of the filter.
