我就是这样用C++加载图片的

#include <opencv2/opencv.hpp>
#include
#include
#include
#include

using namespace cv;
using namespace std;
int main() {
std::string pattern_jpg = “D:\Photo and Video\destop1\*.jpg”;

std::vector<cv::String> image_files;
cv::glob(pattern_jpg, image_files);
if (image_files.size() == 0) {
	std::cout << "No image files[jpg]" << std::endl;
	return 0;
}

for (unsigned int frame = 0; frame < image_files.size(); ++frame) {//image_file.size()代表文件中总共的图片个数
	Mat image = cv::imread(image_files[frame]);
	imshow("1", image);
	waitKey(30);


}
