When measurements from multiple sensors are combined for real-time motion estimation, the time instant at which each measurement was recorded must be precisely known. In practice, however, the timestamps of each sensor's measurements are typically affected by a delay, which is different for each sensor. This gives rise to a temporal misalignment (i.e., a time offset) between the sensors' data streams. In this work, we propose an online approach for estimating the time offset between the data… CONTINUE READING
