This is the code i used to open USB3.0 IDS camera in opencv.

#include<opencv2/opencv.hpp>
#include<iostream>
using namespace cv;
using namespace std;
int main()
    {
    Mat CameraFrame;
    Mat Grey;
    VideoCapture cap;
    char keypressed;
    cap.open(0);
    if( !cap.isOpened() )
    {cout << "***Could not initialize capturing...***\n";
   return -1;}
   namedWindow("Camera Preview", CV_WINDOW_AUTOSIZE);
   for(;;)
   {cap >> CameraFrame;
   if( CameraFrame.empty() )
   break;
   imshow("Camera Preview", CameraFrame);
   keypressed = (char)waitKey(10);
   if( keypressed == 27 )
   break;}
   cap.release();
  return 0;}
