Starting the Web Camera

in Contributed Library Questions • 1 year ago

I am trying to make an application which will start the web camera. This is a part of a whole application for robot controlling.

The code which I use to start the web camera is

import hypermedia.video.*;        // Imports the OpenCV library
OpenCV opencv;                    // Creates a new OpenCV Object
void setup()
{
size( 320, 240 );
opencv = new OpenCV( this );    // Initialises the OpenCV object
opencv.capture( 320, 240 );     // Opens a video capture stream
}
void draw()
{
opencv.read();                  // Grabs a frame from the camera
image( opencv.image(), 0, 0 ); // Displays the image in the OpenCV buffer to the screen
}

This is giving an error : UnsatisfiedLinkError:hypermedia.video.OpenCV.capture(II)V

I am using Processing 2.0a4 on Windows 7 64 Bit.

The Open CV library CV01 is installed in C:\Users\Subhendu\Documents\Processing\libraries\OpenCV\library

The Processing Library is in C:\Users\Subhendu\Documents\Processing\libraries\ControlP5\library

Please Help

I have a code like this

import JMyron.*;
JMyron m;//a camera object

PFrame f;
secondApplet s;

void setup() {
size(600, 600);
PFrame f = new PFrame();
}

void draw() {
background(255,0,0);
   fill(255);
// rect(10,10,frameCount%100,10);
// s.background(0, 0, 255);
// s.fill(100);
   //s.rect(10,20,frameCount%120,10);
   //s.redraw();
}

public class PFrame extends Frame {
    public PFrame() {
        setBounds(10,100,320,240);
        s = new secondApplet();
        add(s);
        s.init();
        show();
    }
}

public class secondApplet extends PApplet {
    public void setup() {
    size(320,240);
m = new JMyron();//make a new instance of the object
m.start(320,240);//start a capture at 320x240
m.findGlobs(0);//disable the intelligence to speed up frame rate
println("Myron " + m.version());
            }

    public void draw() {
      m.update();//update the camera view
      int[] img = m.image(); //get the normal image of the camera
loadPixels();
for(int i=0;i<width*height;i++){ //loop through all the pixels
pixels[i] = img[i]; //draw each pixel to the screen
}
updatePixels();
    }

void mousePressed()
{saveFrame("####.jpg");
}
public void stop(){
m.stop();//stop the object
super.stop();
}

}

Two windows are opening, but the video is not proper. Please help
