Open WebCam by using javaCV

1. Today I will show you how open the webcam by using javaCV


2. Open your last netbeans project


3. Add a button and I name it as Open WebCam





4. Double click on the button and goto button click event


5. Enter following codes
• To open the webcam

  
CvCapture capture=opencv_highgui.cvCreateCameraCapture(0);
 

Here 0 is a parsing a variable. o is for webcam. If you using another camera you can use 1 or 2 or something.

• Next we have to set the height and with of camera frame

  opencv_highgui.cvSetCaptureProperty(capture,opencv_highgui.CV_CAP_PROP_FRAME_HEIGHT,480);
        opencv_highgui.cvSetCaptureProperty(capture,opencv_highgui.CV_CAP_PROP_FRAME_WIDTH,480);
 

• Next we have to make IplImage

  IplImage img=opencv_highgui.cvQueryFrame(capture);
 

• Next add a canves to show the images

  CanvasFrame frame= new CanvasFrame("WebCam Loading");
 

• Now run the programm.
• Can you see, when you try to close can't close the window. As a solution for it you can write above code in this part

 Thread x= new Thread(){
  public void run(){
  }
  
  //above codes here
 };
 x.start();
