c++ - Opencv图像拼接融合(多波段融合)

我正在尝试使用cv::detail::MultiBandBlender中的#include "opencv2/stitching/detail/blenders.hpp"中的OpenCV 3.2中的搅拌器将刚刚缝合在一起的图像中的接缝融合在一起。我可以找到的文档很多，而编码示例更少，但是我设法找到了一个不错的博客来帮助解释here的步骤。

当我运行代码时，我得到以下error:/opencv/modules/core/src/copy.cpp:1176: error: (-215) top >= 0 && bottom >= 0 && left >= 0 && right >= 0 in function copyMakeBorder
这是用于混合的代码(假设找到的针迹，warpPerspective和单应性正确)

//Mask of iamge to be combined so you can get resulting mask
Mat mask1(image1.size(), CV_8UC1, Scalar::all(255));
Mat mask2(image2.size(), CV_8UC1, Scalar::all(255));
Mat image1Updated, image2Updated;
//Warp the masks and the images to their new posistions so their are of all the same  size to be overlayed and blended
warpPerspective(image1, image1Updated, (translation*homography), result.size(), INTER_LINEAR, BORDER_CONSTANT,(0));
warpPerspective(image2, image2Updated, translation, result.size(), INTER_LINEAR, BORDER_TRANSPARENT,   (0));
warpPerspective(mask1, mask1, (translation*homography), result.size(), INTER_LINEAR, BORDER_CONSTANT,(0));
warpPerspective(mask2, mask2, translation, result.size(), INTER_LINEAR, BORDER_TRANSPARENT,   (0));

//create blender
detail::MultiBandBlender blender(false, 5);
//feed images and the mask areas to blend
blender.feed(image1Updated, mask1, Point2f (0,0));
blender.feed(image2Updated, mask2, Point2f (0,0));
//prepare resulting size of image
blender.prepare(Rect(0, 0, result.size().width, result.size().height));
Mat result_s, result_mask;
//blend
blender.blend(result_s, result_mask);

当我尝试做blender.feed时发生错误

附带一点说明；为搅拌器制作 mask 时， mask 应该是整个图像，还是只是针迹期间图像彼此重叠的区域？

感谢您的任何帮助

编辑

我有它的工作，但现在得到的结果混合成像。

这是未融合的拼接图像，仅供引用。
关于如何改进的任何想法？

最佳答案

在blender.feed之前使用blender.prepare

重新设计您的 mask (半个255半0)

//Mask of the image to be combined so you can get resulting mask
Mat mask1, mask2;
mask1 = optimalSeamMask(energy, path);
mask2 = ones(mask1.rows, mask1.cols)*255-mask1

Mat image1Updated, image2Updated;
//Warp the masks and the images to their new posistions so their are of all the same  size to be overlayed and blended
warpPerspective(image1, image1Updated, (translation*homography), result.size(), INTER_LINEAR, BORDER_CONSTANT,(0));
warpPerspective(image2, image2Updated, translation, result.size(), INTER_LINEAR, BORDER_TRANSPARENT,   (0));
warpPerspective(mask1, mask1, (translation*homography), result.size(), INTER_LINEAR, BORDER_CONSTANT,(0));
warpPerspective(mask2, mask2, translation, result.size(), INTER_LINEAR, BORDER_TRANSPARENT,   (0));

//create blender
detail::MultiBandBlender blender(false, 5);
//feed images and the mask areas to blend
blender.prepare(Rect(0, 0, result.size().width, result.size().height));
blender.feed(image1Updated, mask1, Point2f (0,0));
blender.feed(image2Updated, mask2, Point2f (0,0));
//prepare resulting size of image
Mat result_s, result_mask;
//blend
blender.blend(result_s, result_mask);
