Abstract (en)
[origin: WO2021121896A1] The invention relates to a method for synchronization of a time system (28) of a main device (12) with a reference time system (30) of a reference device (14), wherein a light signal (22) is emitted using a light signal apparatus (20) of the reference device (14), a light signal section (24) of the light signal (22) being detected in at least one image (26) using a detection apparatus (18) of the main device (12), wherein the light signal section (24) can be associated with a point in time tHG of the time system (28) of the main device (12), the light signal (22) comprising a specified, time-dependent signal sequence (32, 32a, 32b) which has a defined reference to a point in time tRG of the reference time system (30), a time offset Δt (42, 42a, 42b) being determined from a comparison of the detected light signal section (24) with the specified time-dependent signal sequence (32, 32a, 32b) of the light signal (22), wherein a correction by the time offset Δt (42, 42a, 42b) is carried out for the purpose of synchronization. The invention also relates to a system (10) comprising at least one main device (12) and at least one reference device (14) for carrying out the method.
