Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 16:
17. An electronic device comprising:
at least one processor;
at least one non-transitory computer-readable medium comprising data, the data being generated by a camera system and a LIDAR system that are mounted onto a Self-Driving Vehicle (SDV) and are communicatively coupled, via a communication interface, with the at least one processor,
the data including:
(i) image data of the camera system mounted onto the SDV for generating the image data about a pre-determined portion of a surroundings of the SDV,
the camera data being in a form of a sequence of snapshots generated by the camera system with a camera scanning frequency,
the sequence of snapshots representing the pre-determined portion at different moments in time,

(ii) map data from a LIDAR system mounted to the SDV for generating the map data about the surroundings of the SDV including the pre-determined portion,
the map data being in a form of data points generated by the LIDAR system,
the data points representing objects located in different portions of the surroundings of the SDV at different moments in time,

at least one non-transitory computer-readable medium further comprising executable instructions that, when executed by the at least one processor, cause the electronic device to:
cause the camera system and the LIDAR system to provide the image data and the map data in a common time referential,
the common time referential being an indication of an absolute time during which the data is generated;

determine a first timestamp for the map data,
the first timestamp corresponding to a given moment in time in the common time referential during which the LIDAR system generated data points representing objects located in the pre-determined portion;

determine a second timestamp for the image data, the second timestamps corresponding to an other given moment in time in the common time referential during which the camera system has been generating a given snapshot of the pre-determined portion;
determine, a temporal offset between the first timestamp and the second timestamp,
the temporal offset being indicative of a difference between the given moment in time and the other given moment in time in the common time referential;

use the temporal offset to trigger a delay between subsequent snapshots generated by the camera system by adjusting the camera scanning frequency including dividing a duration of the temporal offset among a number of subsequent snapshots to add a respective time delay thereamong,
such that (i) at least one subsequent snapshot is generated by the camera system and (ii) subsequent data points about the pre-determined portion is generated by the LIDAR system, at a same future moment in time in the common time referential.
