SENSOR SYNCHRONIZATION

The disclosure relates to a simultaneous localisation and mapping, SLAM, device a data processing unit, computer program and associated method for receiving first-sensor-data, first-motion-data and first-timing-information associated with the first-sensor-data and the first-motion-data; receiving second-sensor-data, second-motion-data and second- timing-information associated with the second-sensor-data and the second-sensor-motion-data; and correlating the first-motion-data with the second-motion-data to identify a relationship between the first-timing-information and the second-timing-information, in which the identified relationship between the first-timing-information and the second-timing-information defines one or more associations between the first-sensor-data and the second-sensor-data.
