Unfortunately, I don't have the Image Acquisition Toolbox so cannot provide much more help. Perhaps someone more familiar with this toolbox will be able to.

在 MATLAB Online 中打开

For those still looking, initialize the camera before trying to trigger it:

cam = videoinput('gentl', 1); %specify video object
triggerconfig(cam, 'manual'); %allow for manual frame triggering
start(cam) %initialize
trigger(cam); %trigger
