以下是基于GUI界面的MATLAB遥感图像配准软件的代码,包括人工选取控制点和自动选择控制点两种配准方式,并能生成配准后的遥感影像:
```matlab
% 创建GUI界面
fig = uifigure('Name', '遥感图像配准软件');
% 创建菜单栏和文件菜单
menu = uimenu(fig, 'Text', '文件');
uimenu(menu, 'Text', '打开', 'MenuSelectedFcn', @openImage);
uimenu(menu, 'Text', '保存', 'MenuSelectedFcn', @saveImage);
% 创建选择配准方式的单选框
rbg = uibuttongroup(fig, 'Position', [0.05 0.7 0.9 0.2], 'Title', '选择配准方式');
uicontrol(rbg, 'Style', 'radiobutton', 'String', '人工选取控制点', 'Position', [10 50 200 30], 'HandleVisibility', 'off');
uicontrol(rbg, 'Style', 'radiobutton', 'String', '自动选择控制点', 'Position', [10 20 200 30], 'HandleVisibility', 'off');
% 创建图像显示区域
ax1 = uiaxes(fig, 'Position', [0.05 0.2 0.4 0.4]);
ax2 = uiaxes(fig, 'Position', [0.55 0.2 0.4 0.4]);
% 创建控制点设置区域
pnl = uipanel(fig, 'Title', '控制点设置', 'Position', [0.05 0.05 0.9 0.1]);
uicontrol(pnl, 'Style', 'text', 'String', '控制点数量:', 'Position', [10 40 100 20]);
uicontrol(pnl, 'Style', 'edit', 'String', '4', 'Position', [110 40 50 20], 'Callback', @setControlPoint);
uicontrol(pnl, 'Style', 'text', 'String', '控制点位置:', 'Position', [10 10 100 20]);
uicontrol(pnl, 'Style', 'pushbutton', 'String', '手动选择', 'Position', [110 10 100 20], 'Callback', @manualControlPoint);
uicontrol(pnl, 'Style', 'pushbutton', 'String', '自动选择', 'Position', [220 10 100 20], 'Callback', @autoControlPoint);
% 全局变量
global img1 img2 cp;
cp = [];
% 打开图像
function openImage(src, event)
[file, path] = uigetfile({'*.jpg;*.png;*.tif', '图像文件 (*.jpg,*.png,*.tif)'});
if isequal(file, 0) || isequal(path, 0)
return;
end
img = imread(fullfile(path, file));
global img1 img2 cp;
if isempty(img1)
img1 = img;
else
img2 = img;
end
imshow(img, 'Parent', ax1);
end
% 保存图像
function saveImage(src, event)
[file, path] = uiputfile({'*.jpg;*.png;*.tif', '图像文件 (*.jpg,*.png,*.tif)'});
if isequal(file, 0) || isequal(path, 0)
return;
end
global img2;
imwrite(img2, fullfile(path, file));
end
% 设置控制点数量
function setControlPoint(src, event)
global cp;
cp = [];
n = str2double(src.String);
if ~isnan(n) && n > 0
cp = zeros(n, 2);
end
end
% 手动选择控制点
function manualControlPoint(src, event)
global img1 img2 cp;
if isempty(cp) || size(cp, 1) ~= str2double(pnl.Children(2).String)
warndlg('请先设置控制点数量!');
return;
end
[x1, y1] = ginput(size(cp, 1));
[x2, y2] = ginput(size(cp, 1));
cp(:, 1) = x1;
cp(:, 2) = y1;
tform = fitgeotrans(cp, [x2, y2], 'affine');
img2 = imwarp(img1, tform, 'OutputView', imref2d(size(img1)));
imshow(img2, 'Parent', ax2);
end
% 自动选择控制点
function autoControlPoint(src, event)
global img1 img2 cp;
if isempty(cp) || size(cp, 1) ~= str2double(pnl.Children(2).String)
warndlg('请先设置控制点数量!');
return;
end
pts1 = detectSURFFeatures(rgb2gray(img1));
pts2 = detectSURFFeatures(rgb2gray(img2));
[f1, vpts1] = extractFeatures(rgb2gray(img1), pts1);
[f2, vpts2] = extractFeatures(rgb2gray(img2), pts2);
indexPairs = matchFeatures(f1, f2, 'MaxRatio', 0.7);
matchedPoints1 = vpts1(indexPairs(:, 1));
matchedPoints2 = vpts2(indexPairs(:, 2));
if size(matchedPoints1, 1) >= size(cp, 1)
matchedPoints1 = matchedPoints1(1:size(cp, 1));
matchedPoints2 = matchedPoints2(1:size(cp, 1));
end
cp(:, 1) = matchedPoints1.Location(:, 1);
cp(:, 2) = matchedPoints1.Location(:, 2);
tform = fitgeotrans(cp, matchedPoints2.Location, 'affine');
img2 = imwarp(img1, tform, 'OutputView', imref2d(size(img1)));
imshow(img2, 'Parent', ax2);
end
```
