Shutter triggering synchronisation for photogrammetric measurement - measuring triggering opening delay of each and delaying one or more accordingly

摘要

Synchronisation of shutter triggering of at least two photogrammetric measurement chambers involves determining the delay between generating the triggering pulse and the actual shutter opening for each chamber and delaying at least one chamber accordingly. The delay can be determined by using an already provided indicator signal, i.e. the flash contact signal of each shutter. The shutter opening of the faster reacting shutter can be delayed. A defined delay between the shutters can be set up. USE/ADVANTAGE - For synchronising shutter opening of two phtogrammetric measurement chambers or setting defined time intervals.
