今天遇到需求，就是从一个roi图找到其原图，现在只有根据其名称去找，车架号。我的roi图名字如下格式：

就是最后17位的车架号相同。然后我编程如下：
#include "stdio.h"
#include <cv.h>
#include <highgui.h>
#include<iostream>
#include<fstream>
#include<string>
#include "opencv2/opencv.hpp"
#include <opencv2/core/core.hpp>
#include <opencv2/features2d/features2d.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace cv;
using namespace std;
int main(int argc, char *argv[])
{
string img_path;
fstream src_infile("/media/d/Yang/MyData/ji'an'cheguansuo/8-2/chejiahao/list.txt");
// fstream out_infile("/media/d/Yang/MyData/tmp_8_12/list_out.txt");
string srcimg_path,out_path;
string src_name,out_name;
while(src_infile>>srcimg_path)
{
fstream out_infile("/media/d/Yang/MyData/tmp_8_12/list_out.txt");
Mat stcImg=imread(srcimg_path);
int pos=srcimg_path.find_last_of("_")+1;
src_name=srcimg_path.substr(pos,srcimg_path.size()-1-pos+1);
cout<<src_name<<endl;
while (out_infile>>out_path)
{
int pos_=out_path.find_last_of("/")+1;
out_name=out_path.substr(pos_,out_path.size()-1-4-pos_+1);
cout<<out_name<<endl;
//while(1);
if(src_name==out_name)
{
cout<<"~~~~~~~~~~~~~~~~~~~~~~\n";
string oout_path="/media/d/Yang/MyData/tmp_0815/";
oout_path+=out_name;
oout_path+=".jpg";
imwrite(oout_path,stcImg);
}
cout<<endl;
}
}
return 0;
