OpenCV图片拼接的两种方法

https://my.oschina.net/xiaot99/blog/226589

一、原图

                    1.jpg                                        2.jpg                                            3.jpg

 二、拼接效果

1、拼接效果之一：简单拼接，有重叠，看着不太舒服

 

 2、拼接效果之二：高级拼接，这下貌似好多了

 三、源代码（一）

#include <cv.h> #include <highgui.h> #include <stdlib.h> #pragma comment(lib,"opencv_core245.lib") #pragma comment(lib,"opencv_highgui245.lib") int main(){         char* file[3]={"1.jpg","2.jpg","3.jpg"};//3张原始图片         IplImage* pImg[3];           int i;              for(i=0;i<3;++i)                 pImg[i]=cvLoadImage(file[i]);              int sw=pImg[0]->width;         int sh=pImg[0]->height;     IplImage* dstImg = cvCreateImage(cvSize(sw*3,sh),pImg[0]->depth,pImg[0]->nChannels);              cvZero(dstImg);     printf("Please wait...\n");          for(i=0;i<3;++i) {                   cvSetImageROI(dstImg, cvRect(i*sw,0,sw,sh));                  cvCopy(pImg[i], dstImg);                   cvResetImageROI(dstImg);         }          cvNamedWindow("dstImg");         cvShowImage("dstImg", dstImg);        cvSaveImage("result1.jpg",dstImg);//拼接图片之一              cvWaitKey(0);              for(i=0;i<3;++i)            cvReleaseImage(&pImg[i]);                   cvReleaseImage(&dstImg);          cvDestroyWindow("dstImg");            system("pause");          return 0; }

 

2、源代码（二）

#include <iostream> #include <fstream> #include "opencv2/highgui/highgui.hpp "#include "opencv2/stitching/stitcher.hpp" using namespace std; using namespace cv; #pragma comment(lib,"opencv_core245.lib") #pragma comment(lib,"opencv_highgui245.lib") #pragma comment(lib,"opencv_stitching245.lib") int main(void) {          string srcFile[3]={"1.jpg","2.jpg","3.jpg"};          string dstFile="result.jpg";          vector<Mat> imgs;     for(int i=0;i<3;++i)          {                    Mat img=imread(srcFile[i]);                    if (img.empty())                    {                            cout<<"Can't read image '"<<srcFile[i]<<"'\n";                            system("pause");                            return -1;                     }                   imgs.push_back(img);          }     cout<<"Please wait..."<<endl;          Mat pano;          Stitcher stitcher = Stitcher::createDefault(false);          Stitcher::Status status = stitcher.stitch(imgs, pano);     if (status != Stitcher::OK)          {                   cout<<"Can't stitch images, error code=" <<int(status)<<endl;                   system("pause");                  return -1;          }     imwrite(dstFile, pano);         namedWindow("Result");          imshow("Result",pano);               waitKey(0);               destroyWindow("Result");     system("pause");          return 0; }

 

注：

1、原始图片(1,2,3)来源http://blog.youkuaiyun.com/yang_xian521/article/details/7589431，缩放至1/4

2、代码（一）参考http://www.cnblogs.com/CBDoctor/archive/2011/09/19/2180998.html ，有较小改动

3、代码（二）参考OpenCV自带samples\cpp\stitching.cpp，改动较大
