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);
}
}
