Re: Announcing SimpleOpenNI

I just uploaded a linux version:

SimpleOpenNI 0.15 Linux/x68-32

I'm curious if this works, i only tested it with ubuntu/kubuntu.

ubboo.mom..

I'm under windows seven (in french which produce sometimes trouble)
At first, the library was not running. In fact, I previously had installed CL NUI drivers. After having removing the CL NUI drivesr and rebooting my computer I finally was able to run all the sample.

one issue:

SimpleOpenNI_User example ran one time without error but now it generate an error
#
# A fatal error has been detected by the Java Runtime Environment:
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6cc1c905, pid=2404, tid=1448

One question:
where can I found out explanation of gesture recognition (wave, click, RaiseHand, others?)

Re: Re: Announcing SimpleOpenNI

Most of the time the installation makes the problems. Can you verify your installation works ?
Run the examples of the NITE installation, located there:
C:\Program Files (x86)\Prime Sense\NITE\Samples\Bin\Release

You have to change the xml files(not for SimpleOpenNI, just for testing the NITE examples):

http://www.codeproject.com/Articles/148251/How-to-Successfully-Install-Kinect-on-Windows-Open.aspx?msg=3778324

Also check out the device manager if the old NUI drivers are not interfering with OpenNI.

If you have further problems, please write to the project list:

Re: Announcing SimpleOpenNI

Maxxxoh,

awesome work, thank you!

I've followed the instructions for installing on windows, and It's all gone very well. I have the camera and motor visible in device manager, and the OpenSense examples work for me (once I changed the XML files, as described in the link in the post above).

The problem is I can't compile any of the processing examples on my win7 64bit machine (using processing version 1.2.1). I'm getting the error..

processing.app.debug.RunnerException: UnsatisfiedLinkError: C:UjimProcessinglibrariesSimpleOpenNIlibrarySimpleOpenNI.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

I've seen this with OpenGL and it was fixed by using 64bit openGL drivers.

You mentioned in your first post that you'd tested this on 64bit Win7, can you point me towards the drivers you used?

thanks

Jim

Re: Re: Announcing SimpleOpenNI

hi jim,

do you run your processing sketch from eclipse(64bit java) ?

I already had this case, check out this thread:

http://groups.google.com/group/simple-openni-discuss/browse_thread/thread/90ca532930716b05

The library for OpenNI + the simpleOpenNI are in 32bit(cpp libs), so this gives problems if you

want to mix it with 64bit stuff. If you let all components run with 32bit this works well in a 64bit environment.

Re: Re: Announcing SimpleOpenNI

You have to do the 'Psi' pose for calibration, this video show this at the beginning:

http://www.youtube.com/watch?v=2Uv9dWvCngs&feature=player_embedded

It works better:

- Make fists

- Use tight cloths

- stand 2.5m from the cam + the hole body should be visible

Re: Announcing SimpleOpenNI

@Maxxxoh

No, I'm not using eclipse, I use the processing IDE, but with a manual 64bit java install. I regularly work with 3d datasets that run into GBs so I need the 64bit advantage for memory.

In the link you posted above, you mention that you could compile the drivers for 64bit, are these available? Would be awesome if they were :)

Re: Re: Announcing SimpleOpenNI

hi jim,

sorry, was maybe a bit confusing, i just tested it with a 64-bit system, but the hole thing runs 32-bit.

I can't compile for 64bit, because the NITE libs are 32-bit:

http://groups.google.com/group/openni-dev/browse_thread/thread/cb31bb4c8a9cc8d5

They plan to release a real 64bit version, but maybe in the next release

Re: Announcing SimpleOpenNI

Awesome!

It works great, unlike every other ones that I tried.. Thanks a lot!

is it the kinect that's sending depthimage at such slow frameRate? about 8fps, all other modes (Scene,IR,RGB) are at around 30fps.

and is there a way to change the size of the capture as with a webcam (Capture(this,width,height,fps))?

maxxxoh

Re: Re: Announcing SimpleOpenNI

2 years ago

Hopefully you use an old version, i did made an update to 0.17, where i improved the performance:
http://groups.google.com/group/simple-openni-discuss/browse_frm/thread/d270f524a4cc0e63
But generally it should run as smooth as the other modes.

You can change the image cam resolution with enableRgb(w,h,fps), but only certain resolutions will work, for example:
640* 480* 30
1280 * 1024 * 10

Re: Announcing SimpleOpenNI

Hi Max,

This is great. I had been avoiding downloading this since I had already installed OpenNI according to this tutorial, and was worried that I would get conflicts, but I just realized that you have this operating as a library, with examples, so I've installed that, and all the examples work great (OS X 10.6 btw).

A few notes/questions though...

1) Your "SimpleOpenNI_SceneDepth" example has a typo on Line 19 - one too many commas after "this"

context = new SimpleOpenNI(this,,SimpleOpenNI.RUN_MODE_SINGLE_THREADED);

2) I had been wondering about Hand/Gesture recognition! (the Sensebloom examples really only use osceleton...) I located and edited the Nite.ini file (which is at "Nite-1.3.0.18/XnVHandGenerator/Data" on OSX (maybe you can put that in your example along with the Windows path?)... at least under the install I used) to take out the two semi-colons, and restarted Processing, but I can't seem to get a second hand to be registered. So I'd like to *bump* Ubboo's question above about where we can find out more info on the different gesture recognition/registration methods... ie. does it use haar_cascade files? Are they TUIO gestures ? etc...

Thanks!

EDIT:

Sorry, i just found the Documentation folder under the NITE directory, which has some pretty readable and useful pdf's explaining things...

Jesse Sco..

Re: Announcing SimpleOpenNI

2 years ago

RE: Multiple Hands / Nite.ini

My mistake, the actual file is at /usr/etc/primesense/XnVHandGenerator/Nite.ini

The /usr directory is hidden by default, so if you are on OSX, type the following into Terminal (/Applications/Utilities/Terminal) and press enter :

defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder

then

defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder

to re-hide files, if desired.

uninstalling and installing again (without making anything

if you draw the depthMap in 3d then the hole thing get pretty slow, you can optimize this in opengl(vbo), or just leave it,
if you don't need to visualise the depthBuffer.

eduardomo..

Re: Announcing SimpleOpenNI

2 years ago

I´ve been testing to optimize the speed, but the problem comes when the depthBuffer is readed, only 12 or 13 fps, included if you don´t paint any 3dpoint. But, if you only read the skeleton data, or nite hands, you can get 30 fps, or 60 with SimpleOpenNI.RUN_MODE_MULTI_THREADED, but really are 30, that is perfect.

Another question, with SimpleOpenNI.RUN_MODE_MULTI_THREADED and depthMap access, the framerate is in 10 fps, is this a error?

Re: Announcing SimpleOpenNI

2 years ago

I have a quick question — I've used glgraphics to create a GLModel out of the depth map. The updating and rendering of the vertices is super quick. But my sketch is bogging down on the line in red (line 13), which fetches and casts the depth coordinates (stored as a PVector).

With random vertex updates, I easily hit 60fps. With this code, I cruise at 12fps (no matter how many points are actually getting rendered). If I only do the PVector reading & casting every other frame, I get a jump in framerate.

Can anyone suggest a better-performing way to do this, using the depthMapRealWorld() function? Or am I going to have to pull in the raw greyscale depth map and use it in a vertex shader to adjust the depth of each vertex?

void draw(){
context.update();
int[] depthMap = context.depthMap();
PVector depthPoint;
depthPoints.beginUpdateVertices();
depthPoint = new PVector(0,0,0);
for(int i=0; i<depthMap.length; i++){
depthPoint = context.depthMapRealWorld()[i];
depthPoints.updateVertex(i, depthPoint.x, depthPoint.y, depthPoint.z);
}
depthPoints.endUpdateVertices();
GLGraphics renderer = (GLGraphics)g;
renderer.beginGL();
background(255);
drawOrigin();
stroke(0);
fill(0);
strokeWeight(1);
renderer.model(depthPoints);
renderer.endGL();

Make sure to remove all the NUI drivers first. Then follow the installation instructions.

Re: Announcing SimpleOpenNI

After changing every Nite.ini file on my system (I had way too many) I am finally convinced the one that has effect for processing is not /usr/etc/primesense/XnVHandGenerator/Nite.ini as it says in the sketch header but

/usr/etc/primesense/Hands_1_3_1/Nite.ini

Now I have a green and a red tracker. Sweet. Never seen any tracking so stable.

- :
- * - *Works with Processing 2.0
- *Multiple sensors with the generators
- *
v0.22 , 11/13/2011,
New:
-

-

- Added methods to access and query multiple cameras:
Be aware that you shouldn't put the cameras at the same usb bus(usb performance!).
- SimpleOpenNI(int cameraIndex,PApplet parent) - setup the specific camera
- SimpleOpenNI.updateAll() - updates all cameras (static method)
- int deviceCount() - returns the count of cameras (static method)
- int deviceNames(StrVector strList) - gives a list of the cameras that are available and
returns the count (static method)
- Added new example:
- 'MultiCam.pde' - Shows how to use multiple cameras
The multicamera support works at the moment only for the depthMap, rgbMap and the infraRedMap.

hi guys!

maxxxoh just released a new version, and that's great because he updated the sensorKinect so the sketch can open faster!

http://code.google.com/p/simple-openni/downloads/list

v0.24 , 12/27/2011, 
		- Updated to versions:
			OpenNI 1.5.2.7
			NITE 1.5.2.7
			SensorKinect 5.1.025	
			Sensor 5.1.025	
		- Use new Avin2 Kinect drivers, now the mac starts up much faster!
		- Added better checks if SimpleOpenNI could be started. Extended all examples.
		- Added OpenNI install files for every release and plattform 
		- Added support for export application(no applets), this application works on your machine, if you want to use the app on another machine,
		  you still have to install OpenNI/NITE/Sensor libs.
		  There is a bug in Processing 2.0 for linux, so the export won't work, only if you change the app script: 
			-Djava.library.path="$APPDIR:$APPDIRlib"
			to
			-Djava.library.path="$APPDIR:$APPDIR/lib"
		  http://code.google.com/p/processing/issues/detail?id=945&q=mrn&colspec=Stars ID Type Status Priority%	20Owner Summary
		- Updated install section on the wiki 
		- Added classpaths to the JavaDoc generator

Re: Announcing SimpleOpenNI

Hi datamosh, I got the second hand detection working. What is need to be done is that simply after downloading the installer file for OpenNI and NITE (OpenNI_NITE_Installer-OSX). We need to go inside data folder and in primesense folder go to Hands_1_5_2 and XnVHandGenerator folder and inside that folder will be Nite.ini (OpenNI_NITE_Installer-OSX -> data -> primesense -> Hands_1_5_2 and XnVHandGenerator). delete the semicolon before the statements and change the code like this

[HandTrackerManager]

AllowMultipleHands=1

TrackAdditionalHands=1

then install the installer file. the replace the library with new one(SimpleOpenNI 0.24) and open the example and hands example and try it...it will detect both hands

i've try and install the content from (32 bits version)

OpenNI_NITE_Installer-Win32-0.26.zip

with

processing-1.5.1-windows.zip

copied the unziped folder SimpleOpenNI from the SimpleOpenNI-0.26.zip

to

processing-1.5.1/modes/java/libraries/SimpleOpenNI

with another pc and did work :) with windows 7 64 bits

there must be a problem with my PC ... !

I'm using SimpleOpenni on a project at the moment and its working great. The only problem is that if the kinect isn't connected to the computer my processing app crashes with an EXCEPTION_ACCESS_VIOLATION error at the SimpleOpenni constructor . I cannot catch this as it is not an exception so it means if the kinect isn't connected to the computer then I cannot run my app.

This is a problem because there are times when I will want to run the app without the kinect.

Is there someway around this, possibly detected whether the kinect is connected through another library before running the SimpleOpenni constructor.

This is different on my PC (Vista 32 Bit).

If I run one of the examples and the kinect is not connected, it just works and I get the textoutput as expected (see below)

context = new SimpleOpenNI(this);

// disable mirror
context.setMirror(false);

// enable depthMap generation
if(context.enableDepth() == false)
{
     println("Can't open the depthMap, maybe the camera is not connected!");
     exit();
     return;
}

I'm on xp and it crashes (no exception) whenever you try to call a method if the kinect is not connected

I'm still trying to find a solution to this problem, the javadocs for SimpleOpenni mentions a static deviceCount() method but whenever I try calling it SimpleOpenni.deviceCount(); I get a deviceCount() does not exist error?

I get this error:

Can't load SimpleOpenNI library (SimpleOpenNI64) : java.lang.UnsatisfiedLinkError: C:\Users\metroalien\Documents\Processing\libraries\SimpleOpenNI\library\SimpleOpenNI64.dll: Can't find dependent libraries

is this because Processing is not using the 64bit Java? How do I fix it so Processing is pointing to 64bit Java in C:\Program Files\Java\jdk1.7.0_04\bin?

Hi! I'm finding something a bit strange.

sceneImage() normally outputs an image with just the recognized users in the scene, right? But in the RecorderPlay example the output to sceneImage() is the depthImage with the users highlighted in colours.

I'm getting the same behaviour whenever I record the depth information into a file like this:

context.addNodeToRecording(SimpleOpenNI.NODE_DEPTH, SimpleOpenNI.CODEC_16Z_EMB_TABLES);

I have also tried the CODEC_16Z and CODEC_CODEC_8Z codecs with the same outcome.

I tried recording the sceneImage directly too, using

context.addNodeToRecording(SimpleOpenNI.NODE_SCENE, SimpleOpenNI.CODEC_JPEG);

But this generates a 52 bytes file.

Im using:

SimpleOpenNI 0.27

Processing 1.5

Windows XP 32bits

Thanks!

I also have some problems with the recorder functionality.

I record the kinect data like in the example of SimpleOpenNI:

// setup the recording
kinect.enableRecorder(SimpleOpenNI.RECORD_MEDIUM_FILE, "test.oni");
// select the recording channels
kinect.addNodeToRecording(SimpleOpenNI.NODE_DEPTH,
SimpleOpenNI.CODEC_16Z_EMB_TABLES);

But I cannot playback it because the file cannot be load:

if (kinect.openFileRecording("test.oni") == false){
println("Cannot open recording");
}

I can open the test.oni with the OpenNI VIewer, but I cannot load it in processing???

Sometimes I get the same error with the SampleOpenNI RecorderPlay example, but I cannot determine the reason for this. Any idea?

SimpleOpenNI 0.27

Processing 1.5.1
