Dynamic display multiple video feed from multiple webcam
I have implemented code for capturing live video feed from webcam. But the code i have implemented is used 4 cams only. I want to make it dynamic. I.e: If i connect 2 webcam then it should display two windows with live feed. If i connect 3 cams then it should get 3 windows with live feed from all three cameras. I am getting the number of cameras being connected to the system using videoInput.h So now only part is how to make it dynamic for webcam. Here's the code.
int main(){
//Create matrix to store image
Mat image;
Mat image1;
Mat image2;
Mat image3;
//Mat image1;
//initailize capture
videoInput VI;
int numDevices = VI.listDevices();
VideoCapture cap;
VideoCapture cap1;
VideoCapture cap2;
VideoCapture cap3;
bool x = false;
//VideoCapture cap1;
cap.open(0);
cap1.open(1);
cap2.open(2);
cap3.open(3);
namedWindow("Camera 1",1);
namedWindow("Camera 2",1);
namedWindow("Camera 3",1);
namedWindow("Camera 4",1);
while(1){
//copy webcam stream to image
cap >> image;
cap1 >> image1;
cap2 >> image2;
cap3 >> image3;
cap4 >> image4;
//cap1 >> image1;
imshow("Camera 1",image);
imshow("Camera 2",image1);
imshow("Camera 3",image2);
imshow("Camera 4",image3);
//imshow("Camera 2",image1);
//delay 33ms
waitKey(33);
}
}
