Temporal Calibration in Multisensor Tracking Setups
8th IEEE and ACM International Symposium on Mixed and Augmented Reality (ISMAR 2009), Orlando, USA, October 2009, pp. 177-178 (bib)

Spatial tracking is one of the most challenging parts of Augmented Reality. Many AR applications rely on the fusion of several tracking systems in order to optimize the overall performance. While the topic of sensor fusion has already seen considerable interest, most results only deal with the integration of particular setups. A crucial part of sensor fusion is the temporal alignment of the sensor signals, as sensors in general are not synchronized. We present a general method to calibrate the temporal offset between different sensors by applying the normalized cross correlation method.
