ok, so i am pretty new to processing, and familar with arduino. I have working code that uses the opencv library facial tracking software to serially communicate with a servo in arduino.
i basically want to use the facial detection software to move the servos degrees of movements on the movements of the face recognized. (make sense?)
heres my code on both ends
processing code:
import hypermedia.video.*;
import java.awt.Rectangle;
import processing.serial.*;
int gx = 15;
int gy = 35;
int spos=90;
Serial port;
OpenCV opencv;
// contrast/brightness values
int contrast_value = 0;
int brightness_value = 0;
void setup() {
size( 320, 240 );
opencv = new OpenCV( this );
opencv.capture( width, height ); // open video stream
opencv.cascade( OpenCV.CASCADE_FRONTALFACE_ALT ); // load detection description, here-> front face detection : "haarcascade_frontalface_alt.xml"
// print usage
println( "Drag mouse on X-axis inside this sketch window to change contrast" );
println( "Drag mouse on Y-axis inside this sketch window to change brightness" );
println(Serial.list());
port = new Serial(this, Serial.list()[1], 9600);
}
public void stop() {
opencv.stop();
super.stop();
}
void draw() {
// grab a new frame
// and convert to gray
opencv.read();
opencv.convert( RGB );
opencv.contrast( contrast_value );
opencv.brightness( brightness_value );
// proceed detection
Rectangle[] faces = opencv.detect( 1.2, 2, OpenCV.HAAR_DO_CANNY_PRUNING, 40, 40 );
// display the image
image( opencv.image(), 0, 0 );
// draw face area(s)
noFill();
stroke(255,1,1);
for( int i=0; i<faces.length; i++ ) {
rect( faces[i].x, faces[i].y, faces[i].width, faces[i].height );
}
for( int i=0; i<faces.length; i++ ) {
update( faces[i].x);
}
}
/**
* Changes contrast/brigthness values
*/
void mouseDragged() {
contrast_value = (int) map( mouseX, 0, width, -128, 128 );
brightness_value = (int) map( mouseY, 0, width, -128, 128 );
}
void update(int x)
{
//Calculate servo postion from mouseX
spos= x/30;
//Output the servo position ( from 0 to 180)
port.write(spos + "a");
gx = x/80;
gy = 100-x/120;
}
and Arduino code:
#include <Servo.h>
Servo neck;
int xPos=0;
int yPos = 0;
void setup() {
Serial.begin(9600);
neck.attach(13);
}
void loop() {
if(Serial.available() >0) {
xPos=Serial.read();
yPos=Serial.read();
}
int xServo = map(xPos, 0, 320, 20, 70);
int yServo = map(yPos, 0, 240, 20, 70);
neck.write(xServo);
Serial.println("testing....");
}
thanks in advance!!!
