c++中批量读取图片和读取txt文件中的数据

 下面是批量读取图片和txt中的数据代码，方便自己以后直接复制粘贴。

#include<opencv2/opencv.hpp>
#include<opencv2/core/core.hpp>
#include<opencv2/highgui/highgui.hpp> 
#include <fstream>
#include <cstring>
#include<sstream>

int main(){
	//批量读取图片
	std::string path = "E:\\zoomlion\\data\\smallDataSets\\smallDataSets\\test\\imgs\\*.jpg";
	std::vector<cv::String> imgs_file;
	cv::glob(imgs_path, imgs_file);
	if (imgs_file.size() == 0){
		std::cout << "No Images" << std::endl;
		return 0;
	}
	for (int i = 0; i < imgs_file.size(); i++){
		cv::namedWindow("dd");
		cv::Mat dd=imread(image_files[i]);
		cv::imshow("dd", dd);
	}
	cv::waitKeyEx(0);
	return 0;
}

int main(){
	//读取txt文件里面的数据，并转换为int型存储到向量里面去
	std::string test_y = "E:\\zoomlion\\data\\smallDataSets\\smallDataSets\\test\\y_Test.txt";
	std::fstream y_stream;
	std::string y_string;
	std::vector<int> imgs_y;
	y_stream.open(test_y);
	while (y_stream >> y_string){
		std::stringstream tmp;
		int y_data;
		tmp << y_string;
		tmp >> y_data;
		imgs_y.push_back(y_data);
	}
	return 0;
}
