Hello everybody,
I am using App Designer and try to implement a camera into my application.
I have one Callback in which I open a live stream from a camera, when a Button is pushed. To realise this, I use the following Code:
app.vid = videoinput('gentl', 1,'Mono8');hImage = image(app.UIAxes,zeros(1024,1280,3)); app.UIAxes.XLim = [0,1280]; app.UIAxes.YLim = [0,1024]; app.UIAxes.XTick = []; app.UIAxes.YTick = []; pbaspect(app.UIAxes,[1280,1024,1]); preview(app.vid,hImage);
Now, in a different Callback, I want to gather an image from the actual live picture. Right now i am using the following Code:
asd= getdata(app.vid); save('path','asd');
Unfortunately get the following Error when calling:
Error using imaqdevice/getdata (line 154) OBJ is not running and no frames are available.
Can somebody help me to solve my problem?
