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.csdn.net/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
