以下是两点校正的MATLAB代码示例:
```matlab
% 读取图像
image1 = imread('image1.jpg');
image2 = imread('image2.jpg');
% 提取特征点
points1 = detectSURFFeatures(rgb2gray(image1));
points2 = detectSURFFeatures(rgb2gray(image2));
% 提取特征描述符
[features1, validPoints1] = extractFeatures(rgb2gray(image1), points1);
[features2, validPoints2] = extractFeatures(rgb2gray(image2), points2);
% 匹配特征点
indexPairs = matchFeatures(features1, features2);
% 选择最佳匹配点
matchedPoints1 = validPoints1(indexPairs(:, 1));
matchedPoints2 = validPoints2(indexPairs(:, 2));
% 估计单应性矩阵
homographyMatrix = estimateGeometricTransform(matchedPoints1, matchedPoints2, 'projective');
% 对图像进行校正
outputImage = imwarp(image2, homographyMatrix);
% 显示结果
figure;
subplot(1, 2, 1);
imshow(image1);
title('Image 1');
subplot(1, 2, 2);
imshow(outputImage);
title('Corrected Image 2');
```
这段代码实现了两点校正的功能。首先,它读取了两张图像,并使用SURF算法提取了图像中的特征点和特征描述符。然后,它通过匹配特征点找到两张图像之间的对应关系。接下来,它使用这些对应关系估计了单应性矩阵,该矩阵描述了图像之间的几何变换关系。最后,它使用估计的单应性矩阵对第二张图像进行校正,并显示结果。
