I'm looking for a javadoc or some kind of reference that I can use to figure out how to use this library. The "reference" folder in the library just seems to contain info about "FaceData". Thanks.

I'm trying to install SimpleOpen NI on el Capitain but all the help pages are inactive. I finally found the library, but I can't figure out how to install it. I've used plenty of libraries before and it's never been this hard. I need the library to run a processing sketch in the background to connect with Isadora. Help?

I copied a simple example code called slug monster to use with my kinect (1414) and processing replies that the library is not compatible. Sketch>Import Library shows SimpleOpenNI. Any ideas?

Hi, I'm trying to create an array of audios in beads so that they play independently when each SMT zone is touched. The problem I am having is how to initialize and link a different audio file to each zone.

The hope is to be able to use a kinect to play audio files independently within zones. Please let me know if you have any ideas on improving code, or how to use arrays to reduce the footwork of the code.

Thanks

Sorry, I am just starting with shaders. I have read a little but not enough to understand how to change this code.

the code below would build a 3D scene from kinect point cloud data and set all points to white. I just wanted to understand how I could set a matrix of colors dynamically for each point. (basically I just want points closer to kinect to be brighter)

I have tried to implement this, but I couldn't understand how to work with textures yet.

Thank you!

I'm using Processing 2 on OX 10.11.5. I finally seem to have all my libraries installed (and in the correct place) but I'm getting the error UnsatisfiedLinkError: SimpleOpenNI. It IS in the Processing library with all my other libraries, but it just won't run. I've seem that several people have posted this error, but I haven't seen a fix. Has anyone fixed this successfully?

i found the kinect depthimage filter works well with guided-filter in MATLAB. But i don't know how to
write the code in processing...

I am looking to create a visualisation which represents the presence of users and the length of time that they stand in front of the camera for. Firstly, I wrote a code which writes 'Hello' when a user is present. This text grows over time. When the user vacates the room, the text decreases in size until it is no longer visible. The code for this is below.

import SimpleOpenNI.*;
SimpleOpenNI kinect;

int s = 0;

void setup(){
  size(1000,700);

  kinect = new SimpleOpenNI(this);
  kinect.enableDepth();
  //turn on user tracking
  kinect.enableUser();

}

void draw(){

  background(255);

  kinect.update();
  PImage depth = kinect.depthImage();
  //image(depth, 0, 0);

  IntVector userList = new IntVector();

  kinect.getUsers(userList);

  if(userList.size()>0){
   println("There is somebody here");
   s = s + 1;
   textSize(s);
   fill(0);
   textAlign(CENTER);
   text("hello", 500, 350);
  }

if(userList.size()<1){
  println("There is nobody here");
  //s = 0;
  if (s >= 1){
    s = s - 1;
      textSize(s);
   fill(0);
   textAlign(CENTER);
   text("hello", 500, 350);
  }

}
}

It's relatively simple in that it basically asks if there is anybody in the room and returns a yes/no answer. What I want to do now is make it so that when there are several people in the room, they all get their own 'Hello' which grows and shrinks depending on the length of time they stay in the space individually. I know that I need to identify each user separately in order to do this but I am unsure how, and there is little information on the SimpleOpenNI library to reference. I'm wondering whether I could alter/add to the above code, or whether I would need to completely rethink the draw section in order to do what I want to do?

Any help would be appreciated.

Hey, so this links to a previous post—I have been building this code, and finally have it in a spot where it is usable, but KNOW people out there can help me improve it, whether through speeding it up, cutting it down, making it more efficient or more obvious what is going on.

Here's an outline of the project. A kinect and projector are mounted above the ground pointing down. A screensaver will play until someone enters the sensors space, at which point, they will trigger sounds by entering zones on the sketch. As more people enter, the zones adapt a little to make it more interesting.

Any input anyone has on improving this and making it more manageable would be hugely helpful.

So I've been using Shiffman's OpenKinect-for-Processing for a while now, It kept spitting out errors in the console which I assume are dropped frames or something, which I've safely ignored so far. But they are seriously hampering my debugging efforts as they keep flooding the console with messages, obscuring println() messages when I'm debugging. Is there a way of disabling these console messages I'm just unaware of?

(if anyone knows more about the errors themselves, pitch in as well :) )

Sample:

[DepthPacketStreamParser::onDataReceived] not all subsequences received 1020
[DepthPacketStreamParser::onDataReceived] not all subsequences received 511
[TurboJpegRgbPacketProcessor::doProcess] Failed to decompress rgb image! TurboJPEG error: 'Corrupt JPEG data: premature end of data segment'
[RgbPacketStreamParser::onDataReceived] packetsize or sequence doesn't match!
[TurboJpegRgbPacketProcessor::doProcess] Failed to decompress rgb image! TurboJPEG error: 'Corrupt JPEG data: 1672 extraneous bytes before marker 0xd5'
[RgbPacketStreamParser::onDataReceived] packetsize or sequence doesn't match!

Hi guys! I am now working on Kinect, pretty new to it. I want to detect the displacement of one specific joint in LIVE. For example, my right hand is at top right corner now. Then when I move my right hand to the center of the screen, I want the program to calculate the distance travelled by my right hand joint. If possible, save the data in a excel file too later.

Now I am stucked to get the new coordinates of my new position. I draw the skeleton based on the example in Processing: SkeletonColor. I was thinking to add a new function that calculates displacement, but when I put the function inside the for loop in void draw(), the original joint coordinates keep updating. It makes the displacement value 0 (because the new and old joint locations are exactly the same). I also tried to use if function to separate two coordinates within two different frameCount, but it doesn't seem to work at all.

Does anybody has a solution for this? Have you guys heard a project like this before? Answers are very welcome. Thanks in advance!

Best, GH

Hi,

I'm planning to have a projection mapping installation at my house for the upcoming Halloween.

I'm probably going to use the nice Keystone library to adjust the projection surfaces to my house shape.

I also would like to use my Kinect to allow some interaction for (young) visitors.

Step #1 I'm going to use video taken from kinect to show visitors figure in my house windows. Maybe video can be augmented with some sort of sinister filter.

Step #2 Have some "scary" video filter to be applied to video of walking-by visitors and projected on a free surface on my house. I found the "Time Displacement" video example can be a good starting point to do a "scary" visualization of user.

Any other recommendation would be more than welcome.

Thanks, Marco

Hello there!

I have borrowed this code for a school project. It creates a bouncing ball which you can control with you webcam by movements. Sometimes it works just fine, but there seem to be a bug saying

** (java.exe:9372): WARNING **: gstvideo: failed to get caps of pad nat:sink

And then the webcam won't stream. I stumbled upon a discussion with a similar problem, saying using loadPixels() and updatePixels - yet it did not remove the warning.

Below is the code

BackgroundBouncer.pde:

import processing.video.*;
import gab.opencv.*;
import java.awt.Rectangle;

Capture video;
OpenCV opencv;
Ball b;

void setup() {
    size(640,480, P3D); //setup screen size and uses OpenGL gfx driver
    frameRate(30);
    ellipseMode(RADIUS); //set ellipse mode to radius (center point)
    video = new Capture(this, width/2, height/2);
    opencv = new OpenCV(this, width/2, height/2);
    b = new Ball();

    video.start();
    video.read();

    opencv.startBackgroundSubtraction(50,3,0.5); //detects moving objects

}

void draw() {
    clear();
    scale(2);
    loadPixels();
    opencv.loadImage(video); //
    opencv.flip(OpenCV.HORIZONTAL);
    opencv.updateBackground();
    opencv.calculateOpticalFlow(); //apparent motion between two frames caused by moving object or camera
    opencv.dilate(); //makes the image wider and look at neighbour pixels shape over which minimum is taken
    opencv.erode(); //erodes image and look at neighbour pixels shape over which minimum is taken
    noFill();stroke(255,0,0);
    strokeWeight(1);
    image(opencv.getOutput(), 0, 0);
    for (Contour c : opencv.findContours()) {
        Contour hull = c.getConvexHull();
        Rectangle box = hull.getBoundingBox();
        b.strike(c, opencv);
    }
    b.move();
    reflect(b);
    drawBall(b);
    updatePixels();

}

void keyPressed() {
    b.position = new PVector(120, 120);
    b.momentum = new PVector(0, 0);
}
void captureEvent(Capture c) {
  c.read();
}

And the Ball.pde:

float decayRate = 0.9; //how much decay
float scalingFactor = 7; //how big a ball
PVector gravity = new PVector(0, 0.5); //how heavy
class Ball {
  public Ball() {
    size = 25;
    shade = #FF0000; //red ball
    position = new PVector(120, 120); //start position
    momentum = new PVector(0, 0); //a moment of stillness
  }
  public PVector position;
  public PVector momentum;
  public float size;
  public color shade;
  public void move() {
    position.add(momentum);
    momentum.add(gravity);
    momentum.mult(decayRate);
  }
  public void strike(Contour c, OpenCV opencv) {
    for (PVector p : c.getPoints()) {
        if (p.dist(position) <= size) {
            Rectangle box = c.getBoundingBox();
            PVector flow = opencv.getAverageFlowInRegion(box.x, box.y, box.width, box.height);
            flow.mult(scalingFactor);
            momentum.add(flow);
            return;
        }
    }
  }
}

void drawBall(Ball b) {
    fill(b.shade);
    ellipse(b.position.x, b.position.y,
        b.size, b.size);
}

void reflect(Ball b) {
    if (b.position.x - b.size <= 0) {
        b.position.x = b.size;
        b.momentum.x *= -1;
    } else if (b.position.x + b.size > width/2) {
        b.position.x = width/2 - b.size;
        b.momentum.x *= -1;
    }
    if (b.position.y - b.size <= 0) {
        b.position.y = b.size;
        b.momentum.y *= -1;
    } else if (b.position.y + b.size > height/2) {
        b.position.y = height/2 - b.size;
        b.momentum.y *= -1;
    }
}

Any help or tips is welcomed! Thanks in advance.

Is it possible to adjust the length of the bone?

The shape should try to use another puppet. Like this,

Use the 'SimpleopenNI' but did not find the relevant methods.

Anybody experiencing this issue?

For some reason, when I start my computer and run one of the kinect sketches or one of my own, for some reason the kinect doesnt initialize. The sketch runs but the kinect image doesn't, even though I can see its on and running. If I quit and restart the sketch, it runs fine. ANy ideas?

I'm having to use one of the legacy releases (3.0 beta 4) to leverage an old library. Im on a Mac running 10.11 and am using Shiffman's v1 Kinect code for Average Point Tracking as a base for the Kinect stuff.

Thanks for any help.

I should also say I do not get any errors in the console either.

I'm getting a no such method error when trying to run simple open ni in processing 3.0a9. This happens when I call

context = new SimpleOpenNI(this);

I assume this is because PApplet has been jettisoned? Putting opengl as my renderer gave me a bit more verbose information. Not sure exactly where to file this issue, since the simpleopenni google code page is no longer active.

Hello everyone, I'm trying to get some code working on a Raspberry Pi using the freenect libraries and a Kinect V1 (from an Xbox 360). I'm trying to get the example programs in OpenKinect-for-Processing working. They all die though with something like this. I have a freshly compiled version of freenect (libfreenect v0.5.3 Voyager) on the Pi and Processing 3.2 (3.1.2 has the exact same problems though). The freenect libraries work fine though. All the test programs like freenect-glview work fine so this is some problem getting Processing to work with the freenect libs. I'm doing this work for pay for a client (I have my own business as a Pi and Arduino consultant) so at this point I just need to get something working. I'm considering junking freenect and trying to get OpenNi working but I understand that stuff is more complex and could be even more time-consuming to get working. Any one have any ideas? Here's the debug output for RGBDepthTest.pde. All the other example programs die the same way:

Edit: forgot to add yesterday that all this happens on attempting:

kinect = new Kinect(this);

for all the test programs. It's not even getting as far as trying kinect.initDevice(); When I use the debugger I can see that any code up to this point is working fine. Processing just doesn't seem to want to create a kinect object. After that we see the Animation Thread exception...

Kinect used a simple interaction. but kinect not work when other people hide kincet or if kinect is back What do I need to have control ?

I have a working sketch with SimpleOpenNI. Everything is working just like I wanted, but when I export the application it doesn't run. I imported the sketch into Mother and I get te error:

Can't load SimpleOpenNI library (libSimpleOpenNI.jnilib) : java.lang.UnsatisfiedLinkError: Can't load library: /SimpleOpenNI/library/libSimpleOpenNI.jnilib

I already tried copying the simpleOpenNI everywhere and it still doesn't work.

Can anyone give me a tip? Thanks

I'm using Processing 2.0.3 64bit

simpleOpenNI 1.96

in a macos with Mavericks

I'm running Processing 2.2.1 along with SimpleOpenNI 1.96 (based on instructions at http://shiffman.net/p5/kinect/). I modified the DepthImage example sketch and added file writing (code below).

I'm trying to output the depth data from Kinect to .txt files in a folder of my choice. In the Processing IDE, the sketch runs fine; the depth is written to the files correctly.

However I would like this functionality in an .exe file so that another program can run this .exe and read from those files, at run time. Export functionality in Processing IDE runs without errors and I get both win32 and win64 application folder. But if I execute .exe present in either one of them, nothing happens; I cannot see any errors anywhere. Even if I select "Present Mode" while exporting, only a gray screen appears but I cannot see any files being written to the path I supply. Toggle various selections (PresentMode/Export java) on the Export options windows hasn't helped.

I also tried to use savePath() because someone else (not using a kinect application) was able to write data into folders using that. But it did not work for me.

Following is my sketch that works correctly in the IDE:

import SimpleOpenNI.*;
SimpleOpenNI  context;

int[] dmap;
int dsize;
float[] dmapf;
PrintWriter output;
int fitr;
String path;

void setup()
{
   size(640*2, 480);
   fitr=1;
   context = new SimpleOpenNI(this);
   if (context.isInit() == false)
   {
        println("Can't init SimpleOpenNI, maybe the camera is not connected!");
        exit();
        return;
   }



 // mirror is by default enabled
  context.setMirror(false);

  // enable depthMap generation
  context.enableDepth();

  // enable ir generation
  context.enableRGB();

  path = savePath("E:\\SYMMBOT\\DepthReading");
}

void draw()
{
  // update the cam
  context.update();
  dmap = context.depthMap();
  //dmapf = dmap.array();

  output = createWriter(path+"\\depth"+fitr+".txt");
  fitr++;
  int itr = 0;
  for(int i=0; i<480; i++){
    for(int j=0;j<640;j++){
      output.print(dmap[itr]+" ");
      itr++;
    }
    output.println();
  }
  output.flush();
  output.close();
  //dsize = context.depthMapSize();
  background(200, 0, 0); //<>//

  // draw depthImageMap
  image(context.depthImage(), 0, 0);

  // draw irImageMap
  image(context.rgbImage(), context.depthWidth() + 10, 0);
}
