練習 : 打地鼠

準備環境

1. 先安裝 Kinect sdk 以及 KinectDeveloperToolkit

2.執行Processing並將OpenNI放入...\processing2.2.1\modes\java\libraries

3.測試是否能執行

import SimpleOpenNI.*;

SimpleOpenNI show;

void setup()

{

   size(640,480);

   show=new SimpleOpenNI(this);

   show.enableRGB();

   show.enableDepth(); 

}

void draw()

{

   show.update();

    image(show.rgbImage(),0,0,320,240);

    image(show.depthImage(),0,240,320,240);

}

偵測左手

import SimpleOpenNI.*; 

SimpleOpenNI show;

void setup()

{

  size(640, 480);

  show=new SimpleOpenNI(this);

  show.enableRGB();

  show.enableDepth(); 

  show.enableUser();

}

float xpos(PVector pos) 

{

  return width/2+pos.x*500/pos.z;

}

float ypos(PVector pos) 

{

  return height/2-pos.y*500/pos.z;

}

void draw()

{

  show.update();

  background(255);

  image(show.userImage(), 0, 0, 640, 480);

  int [] userlist=show.getUsers();

  PVector pos = new PVector(0, 0, 0);

  for (int userId : show.getUsers ()) 

  {

    show.getJointPositionSkeleton(userId,   SimpleOpenNI.SKEL_LEFT_HAND, pos);

  }

  ellipse(xpos(pos), ypos(pos), 50, 50); 

}

void onNewUser(SimpleOpenNI curContext, int userId) 

{

  curContext.startTrackingSkeleton(userId);

}

偵測頭、手（左右手）

for (int userId : show.getUsers ())

  {

    show.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_LEFT_HAND, pos); 

    show.convertRealWorldToProjective(pos,pos);

    fill(0,0,0);ellipse(pos.x,pos.y,50,50);

    show.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_RIGHT_HAND, pos); 

    fill(255,255,0);ellipse(pos.x,pos.y,50,50);

    show.convertRealWorldToProjective(pos,pos);

    show.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_HEAD, pos);

    show.convertRealWorldToProjective(pos,pos);

    fill(255,0,255);ellipse(pos.x,pos.y,50,50);

}

增加增測點以及優化

 for (int userId : show.getUsers ())

 {

    show.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_LEFT_HAND, pos);

    show.convertRealWorldToProjective(pos,pos);

    fill(0,0,0);ellipse(pos.x,pos.y,50,50); hand1.set(pos); hand1.z=0;

    fill(0,0,0);ellipse(pos.x/10,pos.y/10,5,5); 

    show.getJointPositionSkeleton(userId, SimpleOpenNI.SKEL_RIGHT_HAND, pos);

    show.convertRealWorldToProjective(pos,pos);

    fill(0,0,0);ellipse(pos.x,pos.y,50,50); hand2.set(pos); hand2.z=0;

    fill(0,0,0);ellipse(pos.x/10,pos.y/10,5,5); 

}

  PVector mouse1 = new PVector(mouseX,mouseY, 0);

  if(PVector.dist(mouse1,hand1)<100 || PVector.dist(mouse1,hand2)<100)

  {

    ellipse(mouseX,mouseY,200,200);

  }

}
