Harris角点检测与图像拼接是两个不同的问题,但可以结合起来实现图像拼接。下面是一个简单的matlab代码实现:
1. 首先读入需要拼接的两张图像,并将它们转换为灰度图像。
```matlab
img1 = imread('img1.jpg');
img2 = imread('img2.jpg');
gray1 = rgb2gray(img1);
gray2 = rgb2gray(img2);
```
2. 对两张图像进行Harris角点检测,得到它们的角点坐标。
```matlab
points1 = detectHarrisFeatures(gray1);
points2 = detectHarrisFeatures(gray2);
coords1 = points1.Location;
coords2 = points2.Location;
```
3. 通过匹配两张图像中的角点,计算出它们之间的变换矩阵。
```matlab
indexPairs = matchFeatures(points1, points2);
matchedPoints1 = points1(indexPairs(:, 1));
matchedPoints2 = points2(indexPairs(:, 2));
[tform, inlierPoints1, inlierPoints2] = estimateGeometricTransform(matchedPoints1, matchedPoints2, 'affine');
```
4. 将两张图像拼接在一起。
```matlab
outputView = imref2d(size(gray1) + size(gray2) - [1 1]);
panorama = imwarp(img1, tform, 'OutputView', outputView);
panorama(1:size(img2,1),1:size(img2,2),:) = img2;
```
5. 显示结果。
```matlab
imshow(panorama);
```
需要注意的是,这只是一个简单的实现,实际上图像拼接还有很多细节需要处理,如图像的对齐、重叠区域的融合等。
