Retrieving Timing Information
imaqhwinfo function to get the object constructor for your image acquisition
device and substitute that syntax for the following code.
vid = videoinput('dt' ,1);
2 Configure properties — For this example, configure a trigger frame
delay large enough to produce a noticeable duratio n.
set(vid,'TriggerFrameDelay',50)
3 Start the image acquisition object —Callthestart function to start
the image acquisition object.
start(vid)
The object executes an immediate trigger and begins acquiring frames of
data. The
start function returns control to the command line immediately
but data logging does not b eg in until the trigg er frame delay expire s. After
logging the specified number of frames, the object stops running.
4 Bring the acquired data into the w orkspace —Callthegetdata
function to bring frames into the workspace. Specify a return value to
accept the timing information returned by
getdata.
[data time ] = getdata(vi d);
The variable time is a vector that contains the time each frame was logged,
measured in seconds, relative to the execution of the first trigger. C h eck
the first value in the time vector. It should reflect the duration of the delay
before data logging started.
