sencha touch将变量添加到模板/ List / etc.(sencha touch add variables to templates/List/ etc)

 1）您可以使用带有文件名的 VideoCapture ： 
 
 
 
 filename - 打开的视频文件的名称（例如video.avi）或图像序列（例如img_％02d.jpg ，它将读取样本，如img_00.jpg，img_01.jpg，img_02.jpg，...） 
 
 
 2）或者只是根据计数器更改要加载的图像的名称。 
 
#include <opencv2/opencv.hpp>
#include <string>
#include <iomanip>
#include <sstream>

int main()
{
    std::string folder = "your_folder_with_images";
    std::string suffix = ".jpg";
    int counter = 0;

    cv::Mat myImage;

    while (1)
    {
        std::stringstream ss;
        ss << std::setw(4) << std::setfill('0') << counter; // 0000, 0001, 0002, etc...
        std::string number = ss.str();

        std::string name = folder + number + suffix;
        myImage = cv::imread(name);

        cv::imshow("HEYO", myImage);
        int c = cv::waitKey(1);

        counter++;
    }
    return 0;
}
 
 3）或者你可以使用函数glob来存储与向量中给定模式匹配的所有文件名，然后扫描向量。 这也适用于非连续数字。 
 
#include <opencv2/opencv.hpp>
using namespace cv;

int main()
{
    String folder = "your_folder_with_images/*.jpg";
    vector<String> filenames;

    glob(folder, filenames);

    Mat myImage;

    for (size_t i = 0; i < filenames.size(); ++i)
    {
        myImage = imread(filenames[i]);
        imshow("HEYO", myImage);
        int c = cv::waitKey(1);
    }

    return 0;
}

1) You can use VideoCapture with a filename:
 
 
 
filename – name of the opened video file (eg. video.avi) or image sequence (eg. img_%02d.jpg, which will read samples like img_00.jpg, img_01.jpg, img_02.jpg, ...)
 
 
2) Or simply change the name of the image to load according to a counter.
 
#include <opencv2/opencv.hpp>
#include <string>
#include <iomanip>
#include <sstream>

int main()
{
    std::string folder = "your_folder_with_images";
    std::string suffix = ".jpg";
    int counter = 0;

    cv::Mat myImage;

    while (1)
    {
        std::stringstream ss;
        ss << std::setw(4) << std::setfill('0') << counter; // 0000, 0001, 0002, etc...
        std::string number = ss.str();

        std::string name = folder + number + suffix;
        myImage = cv::imread(name);

        cv::imshow("HEYO", myImage);
        int c = cv::waitKey(1);

        counter++;
    }
    return 0;
}
 
3) Or you can use the function glob to store all the filenames matching a given pattern in a vector, and then scan the vector. This will work also for non-consecutive numbers.
 
#include <opencv2/opencv.hpp>
using namespace cv;

int main()
{
    String folder = "your_folder_with_images/*.jpg";
    vector<String> filenames;

    glob(folder, filenames);

    Mat myImage;

    for (size_t i = 0; i < filenames.size(); ++i)
    {
        myImage = imread(filenames[i]);
        imshow("HEYO", myImage);
        int c = cv::waitKey(1);
    }

    return 0;
}
