Record absolute time of first trigger
The InitialTriggerTime property records the absolute time of the first trigger. The absolute time is recorded as a MATLAB® clock vector.
For all trigger types, InitialTriggerTime records the time when the Logging property is set to 'on'.
To find the time when a subsequent trigger executed, view the Data.AbsTime field of the EventLog property for the particular trigger.
Six-element vector of doubles (MATLAB clock vector)
The default value is .
Create an image acquisition object, vid, for a USB-based webcam.
vid = videoinput('winvideo',1);
Start the object. Because the TriggerType property is set to 'immediate' by default, the trigger executes immediately. The object records the time of the initial trigger.
start(vid) abstime = vid.InitialTriggerTime abstime = 1.0e+003 * 1.9990 0.0020 0.0190 0.0130 0.0260 0.0208
Convert the clock vector into an integer form for display.
t = fix(abstime); sprintf('%d:%d:%d', t(4),t(5),t(6)) ans = 13:26:20
