Synchronizing sensor data using timestamps and signal interpolation

摘要

A method of synchronizing sensor data using timestamps and interpolation. The method includes receiving sequences of time-stamped data indicative of physical events from each of a plurality of sensors; generating an interpolation filter according to desired sampling times; and interpolating the sequences of time-stamped data with the generated filter to obtain sequences of data that are synchronized.

1. A method of synchronizing sensor data comprising:
receiving sequences of time-stamped data indicative of physical events from a plurality of sensors; generating an interpolation filter according to desired sampling times; interpolating the sequences of time-stamped data with the generated interpolation filter to obtain synchronized sequences of data that are synchronized at the desired sampling times; subtracting an approximation of a noise-free sequence from at least one sequence of the time-stamped data to obtain an estimate of noise in the at least one sequence; and adding a filtered sequence to the approximation of the noise-free sequence to obtain a reduced-noise sequence of time-stamped data.
