實戰深度學習OpenCV(二):讀取並播放本地或者攝像頭的視訊

一.讀取並播放的程式碼如下:
#include "pch.h"
#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include<opencv2/imgproc/imgproc.hpp>
using namespace cv;
int main()
{
VideoCapture a;
a.open("C://Users//lenovo//Desktop//geeksong.mp4 ");
while (1)
{
Mat frame;
a >> frame;
imshow("讀取視訊", frame);
waitKey(600);
}
return 0;
}
二.獲取攝像頭裡的視訊,只需要將讀取視訊的路徑改為0就可以了:
#include "pch.h"
#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
using namespace cv;
int main()
{
VideoCapture a;
a.open(0);
while (1)
{
Mat frame;
a >> frame;
imshow("讀取視訊", frame);
waitKey(600);
}
return 0;
}
