現(xiàn)有一些圖片按順序放置在一文件夾jogging1/下，如圖：

需要將其合并轉(zhuǎn)換為一個視頻。

示例：

環(huán)境：Win7+OpenCV3+VS2012

#include<opencv2/opencv.hpp>#include <stdio.h>#include <io.h>#include <string>#include <iostream> #include <fstream> using namespace std;using namespace cv;int main(){  _finddata_t FileInfo;   //讀取圖片所在的路徑  string inPath = "E://image//yu//jogging1//";   string strfind = inPath + "*";  long Handle = _findfirst(strfind.c_str(), &FileInfo);  char filename[300];  Mat src;  if (Handle == -1L)  {     cerr << "can not match the folder path" << endl;     exit(-1);  }  Mat frame;  Mat src0 = imread("E:/image/yu/jogging1/0000.jpg");  Size size = src0.size();  VideoWriter writer;  writer.open("jogging.avi", CV_FOURCC('M', 'J', 'P', 'G'), 25, size, true);  do{    //判斷是否有子目錄    if (FileInfo.attrib & _A_SUBDIR)     {       if ((strcmp(FileInfo.name, ".") != 0) && (strcmp(FileInfo.name, "..") != 0))       {         inPath += FileInfo.name;        cout <<inPath<<endl;       }    }    else    {      cout <<inPath<<FileInfo.name<<endl;      //讀取圖片所在的路徑      string path = "E:/image/yu/jogging1/" + (string)FileInfo.name;      src = imread(path);      imshow("input", src);      writer.write(src);      waitKey(1);    }   } while (_findnext(Handle, &FileInfo) == 0);   _findclose(Handle);    return 0; }
