图像拼接（类stitcher 用于图像拼接）

图像拼接类stitcher
拼接类stitcher 的头文件为：#include
"opencv2/stitching/stitcher.hpp"
1、Stitcher::createDefault

使用默认参数创建一个拼接器

C++: Stitcher Stitcher::createDefault(bool try_use_gpu=false)

2、Stitcher::estimateTransform

这些函数尝试匹配给定的图像和去估计每个摄像机的旋转

Note

Use the functions only if you’re aware of the stitching pipeline, otherwise use Stitcher::stitch().

（注意：只有你熟悉拼接的流程情况使用这个函数，否则使用Stitcher::stitch()）

C++: Status Stitcher::estimateTransform(InputArray images)

C++: Status Stitcher::estimateTransform(InputArray images,const
std::vector<std::vector<Rect>>& rois)
3、Stitcher::stitch
这些函数用于拼接给定的图像

C++: Status Stitcher::stitch(InputArray images,
OutputArray pano)¶

C++: Status Stitcher::stitch(InputArray images,
const std::vector<std::vector<Rect>>& rois, OutputArray pano)
Parameters:images –
Input images（输入图像）

rois –
Region of interest rectangles（感兴趣矩形区域）
pano –
Final pano

Returns:Status code.

简单示例

#include <iostream>

#include <fstream>

#include "opencv2/highgui/highgui.hpp"

#include "opencv2/stitching/stitcher.hpp"

using namespace std;

using namespace cv;

bool try_use_gpu = false;

vector<Mat> imgs; //定义一个Mat类型的向量

string result_name = "result.jpg"; //输出图像的名字

int main(int argc, char* argv[])

{

Mat img1 = imread("E:\\图片\\图像拼接\\1.jpg");//E:\\图片\\图像拼接\\1.jpg

if (img1.empty())

{

cout << "img1 Can't read image '" << endl;

return -1;

}

imshow("图1",img1);

imgs.push_back(img1);

Mat img2=imread("E:\\图片\\图像拼接\\2.jpg");

if (img2.empty())

{

cout << "img2 Can't read image '" << endl;

return -1;

}

imshow("图2",img2);

imgs.push_back(img2);

Mat img3=imread("E:\\图片\\图像拼接\\3.jpg");

if (img3.empty())

{

cout << "img3 Can't read image '" << endl;

return -1;

}

imshow("图3",img3);

imgs.push_back(img3);

Mat pano;

Stitcher stitcher = Stitcher::createDefault(try_use_gpu);

Stitcher::Status status = stitcher.stitch(imgs, pano);

if (status != Stitcher::OK)

{

cout << "Can't stitch images, error code = " << int(status) << endl;

return -1;

}

imshow("拼接图",pano);

imwrite(result_name, pano);

waitKey();

return 0;
