We examine the problem of time delay estimation, or temporal calibration, in the context of multisensor data fusion. Differences in processing intervals and other factors typically lead to a relative delay between measurement from two disparate sensors. Correct (optimal) data fusion demands that the relative delay must either be known in advance or identified online. There have been several recent proposals in the literature to determine the delay parameter using recursive, causal filters such… Expand

TLDR
Various methods in the literature along with a new method proposed by the authors will be presented and compared, based on "extrapolating" the measurement to present time using past and present estimates of the Kalman filter and calculating an optimal gain for this extrapolated measurement. Expand

TLDR
This article suggests how the effect of the synchronization error from an unknown static or slowly varying measurement time-delays in a nonlinear state space system can be handled by linearizing the measurement equation in time. Expand

TLDR
This work proposes an online approach for estimating the time offset between the visual and inertial sensors, and shows that this approach can be employed in pose-tracking with mapped features, in simultaneous localization and mapping, and in visual–inertial odometry. Expand
State estimation with delayed measurements considering uncertainty of time delay
TLDR
