Revision history [back]

I have a point camera USB3 type and connect the camera to my computer using USB 3.0 port.

I came across this code recently. But not sure how to use.

#include "opencv2\opencv.hpp"
#include <stdint.h>

using namespace cv;
using namespace std;

const int fps = 20;

int main(int argv, char** argc) {
    Mat frame;
    VideoCapture vid(0);

if (!vid.isOpened()) {
    return -1;
}

while (vid.read(frame)) {
    imshow("Webcam", frame);

    if (waitKey(1000 / fps) >= 0)
        break;
    }
    return 1;
}

I am not sure how to use this code with my camera. Please help.
