Pb fonction dans interface

Bonjour,

je débute en interface graphique avec GUIDE.
J'ai suivi vos tutos mais je suis bloqué.

J'ai crée un interface graphique

function varargout = cam_therm(varargin)
 
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @cam_therm_OpeningFcn, ...
                   'gui_OutputFcn',  @cam_therm_OutputFcn, ...

    gui_State.gui_Callback = str2func(varargin{1});
end

end
% End initialization code - DO NOT EDIT
 
 
% --- Executes just before cam_therm is made visible.
function cam_therm_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to cam_therm (see VARARGIN)
 
% Choose default command line output for cam_therm
handles.output = hObject;
 
% Update handles structure
guidata(hObject, handles);
 
 
% --- Outputs from this function are returned to the command line.
function varargout = cam_therm_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
 
% Get default command line output from handles structure
varargout{1} = handles.output;
 
 
% --- Executes on button press in load.
function load_Callback(hObject, eventdata, handles)
axes(handles.axes1);
cam = webcam ('Microsoft® LifeCam Studio(TM)');
webcam_image= snapshot(cam);
imshow(webcam_image);
save('webcam_image');
axes(handles.axes2);
vid = gigecam('169.254.0.1','PixelFormat', 'Mono16');
IR = snapshot(vid);
IR_image = imadjust(IR,stretchlim(IR),[]);
imshow(IR_image); 
save('IR_image');
 
 
% --- Executes on button press in interp.
function interp_Callback(hObject, eventdata, handles)
load ('webcam_image');
load ('IR_image');
cpselect(webcam_image,IR_image);
 
% --- Executes on button press in transfo.
function transfo_Callback(hObject, eventdata, handles)
tform = fitgeotrans(movingPoints,fixedPoints,'affine');
 
% --- Executes on button press in save.
function save_Callback(hObject, eventdata, handles)
save('tform.mat', 'tform');
 
 
% --- Executes on button press in verif.
function verif_Callback(hObject, eventdata, handles)
axes (handles.axes3);
Roriginal = imref2d(size(IR_image));
save('Roriginal.mat', 'Roriginal');
recovered = imwarp(webcam_image,tform,'OutputView',Roriginal);
imshowpair(IR_image,recovered,'blend')

mais j'ai un problème avec cette fonction

Code:

1
2
function transfo_Callback(hObject, eventdata, handles)
tform = fitgeotrans(movingPoints,fixedPoints,'affine');

elle ne veux pas se lancer quand je clique sur le bouton.

Une idée?

merci

Où sont définies les variables movingPoints et fixedPoints

D'autre part, il faut utiliser la structure handles pour passer les variables utiles entre les fonctions.

Par exemple :

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
function load_Callback(hObject, eventdata, handles)
axes(handles.axes1);
cam = webcam ('Microsoft® LifeCam Studio(TM)');
handles.webcam_image= snapshot(cam);
imshow(handles.webcam_image);
axes(handles.axes2);
vid = gigecam('169.254.0.1','PixelFormat', 'Mono16');
IR = snapshot(vid);
handles.IR_image = imadjust(IR,stretchlim(IR),[]);
imshow(handles.IR_image); 
 
guidata(gcbf, handles);
 
% --- Executes on button press in interp.
function interp_Callback(hObject, eventdata, handles)
 
cpselect(handles.webcam_image,handles.IR_image);

les variables movingPoints et fixedPoints sont des variables qui sont crée grâce à la fonction cpselect et qui sont enregsitré dans le workspace.
Je ne comprend pas pourquoi il veux pas les charger pour exécuter la commande tform

Merci pour les autres conseils.

Les variables définies dans les fonctions ne sont visibles que à l'intérieur de ces fonctions.

Bref, voici comment faire pour récupérer les variables :
Code:

1 2 3 4 5 6 7 8 9 % --- Executes on button press in transfo. function transfo_Callback(hObject, eventdata, handles) movingPoints = evalin('base', 'movingPoints'); fixedPoints = evalin('base', 'fixedPoints'); handles.tform = fitgeotrans(movingPoints, fixedPoints, 'affine'); guidata(gcbf, handles);
