if true % function frameshow_Callback(hObject, eventdata, handles) global t %%%%顏色辨識timer global t1 t1=timer('TimerFcn',{@timerCallback1,handles},'ExecutionMode', 'fixedDelay','Period', 0.1); guidata(hObject,handles); stop(t); start(t1); function timerCallback1(hObject, eventdata, handles) global vid global t1 global frame
if (vid==-1) msgbox('請首先進行預覽!'); stop(t1); return; end axes(handles.axesshow); frame=getsnapshot(vid); imshow(frame); end
if true % function numberdetect_Callback(hObject, eventdata, handles) global t global t1 t=timer('TimerFcn',{@timerCallback3,handles},'ExecutionMode', 'fixedDelay','Period', 0.1); guidata(hObject,handles); stop(t1); start(t); function timerCallback3(hObject, eventdata, handles) global vid global t global frame global c if (vid==-1) msgbox('請首先進行預覽!'); stop(t); return; end frame=getsnapshot(vid); imagen = rgb2gray(frame); threshold = graythresh(imagen); end i want to use 2 timer to show the camera image but Interaction use show the error:Error while evaluating TimerFcn for timer 'timer-158'
