Beschreibung
Zusammenfassung:	Method and device for acquiring stream of the precisely time-stamped images, including the modulated light source, controlled by the absolute global real-time-base (e.g. provided by global navigation satellite system (GNSS) controller) and the image acquisition and processing unit, decoding the light modulation waveform and determining the time-stamp for every image frame. The GNSS time and position messages can be used to provide the full time- and location stamps for each frame. Multi-element light sources can be used to have more informative light modulation in the time domain. For time-stamping of several image streams (e.g. from several cameras) multiple light sources with the same modulation can be used.
