opencv3.x遍历文件夹读取图片

#include 
#include 
using namespace std;
using namespace cv;
int main(){
    //用void glob(String pattern, std::vector& result, bool recursive = false);当recursive为false时，仅仅遍历指定文件夹内符合模式的文件，当recursive为true时，会同时遍历指定文件夹的子文件夹
    //pattern要绝对路径 其它测试有问题
    string pattern = "D:/Acodes/data/*.jpg";
    //cout << pattern << endl;
    vector images;
    // 必须cv的String
    vector fn;
    glob(pattern, fn, false);
    size_t count = fn.size();
    cout << count << endl;
    for (int i = 0; i < count; i++){
        images.push_back(imread(fn[i]));
        imshow("jaj", images[i]);
        waitKey(10);
    }
    return 1;
}
