My project is to detect defects in a solar panel,where solar panels are passed through a conveyor belt on a real time basis.When defective solar panels are found they are rejected . As my camera takes more than 20 frames a second, I don't need that.Instead I need my program to work in the way to capture one single frame at every 2 seconds only.I use opencv3.2 c++ .Here I cite the basic program for a live video .Pls help me with a solution. I use ids usb3.0 camera.

include<opencv2 opencv.hpp="">

include<iostream>

using namespace cv; using namespace std; int main() { Mat CameraFrame; Mat Grey; VideoCapture cap; char keypressed; //Opens the first imaging device. cap.open(0); //Check whether user selected camera is opened successfully. if( !cap.isOpened() ) { cout << "Could not initialize capturing...\n"; return -1; } //Create a windows to display camera preview. namedWindow("Camera Preview", CV_WINDOW_AUTOSIZE); //Loop infinitely to fetch frame from camera and display it. for(;;) { //Fetch frame from camera. cap >> CameraFrame; //Check whether received frame has valid pointer. if( CameraFrame.empty() ) break; //Display the received frame imshow("Camera Preview", CameraFrame); //Wait for Escape keyevent to exit from loop keypressed = (char)waitKey(10); if( keypressed == 27 ) break; } //Release the camera interface. cap.release(); return 0; }
