Improved angular velocity accuracy when using more sensors: Our sensor fusion methodologies can accommodate any number of sensors; however, it requires at least three sensors for the rigid body formulation. We compared our visual localization sensor transforms and particle filter methodology when using the full four-sensor network against the minimal three-sensor network. We observed a significantly higher (p < 0.05) errors when using the minimal three-sensor network in estimating (a) peak angular velocity magnitude; however, no significant change in accuracy for (b) peak angular acceleration magnitude and (c) peak linear acceleration magnitude estimates.
