C# on Kinect

[Asim]

Hey,

I have just moved to using OpenNi on Kinect (from PS). I had quite a
hard time getting it up and running (avin's posts were a big help!). I
had written some code earlier on C# using the sensor provided by
primesense (using ManagedNite.dll).

This might seem a little silly... but how do i make my project point
to the right XML file for the sensor. I tried creating a "Data
\SampleTracking.xml" in my Debug directory, but wasn't successful.

Any ideas?

[SOLVED]... as i said... it was a silly question :)

Woohoo... Kinect + NITE + C# = Its gonna be a long long night :)

[Rui Marinho]

How did u accomplish, when i try to use the wrapper i get that the xml
file is not found also...

[mitchBCAA]

any code sample to startwiht c# on openni ?

[Joshua Blake]

I uploaded this C# sample:

http://dl.dropbox.com/u/7911268/managed%20OpenNI.zip

 

It just tracks sessions and hand points and outputs them to the console.

Hi Joshua,
I've got a problem running your app - I get ManagedNite.XnMException
when in context.Init(); .

Samples from Prime Sense and OpenNI works well.

Can you post a stacktrace?

Sure,

" w System.Environment.GetStackTrace(Exception e, Boolean
needFileInfo)\r\n w System.Environment.get_StackTrace()\r\n w
NITEconsole.Program.Main(String[] args) w D:\\OpenNI\\NITEconsole\
\Program.cs:wiersz 22\r\n w
System.AppDomain._nExecuteAssembly(RuntimeAssembly assembly, String[]
args)\r\n w System.AppDomain.ExecuteAssembly(String assemblyFile,
Evidence assemblySecurity, String[] args)\r\n w

\n w System.Threading.ThreadHelper.ThreadStart_Context(Object state)
\r\n w System.Threading.ExecutionContext.Run(ExecutionContext

ignoreSyncCtx)\r\n w
System.Threading.ExecutionContext.Run(ExecutionContext

wiersz = line

Thanks for helping.

Hi Łukasz,
Two common causes:
1. ManagedNite.dll is hard coded to look for the config file called
openni.xml in the data subfolder of directory where exe is run.
2. Make sure you have entered the NITE license number during installation.

Best,
-Szymon

Hi Szymon,
I managed to pass ontext.Init(); line - Kinect's IR light strats to
glow when debugging, so I've got the connection. However I get an
error very next line :
sessionManager = new XnMSessionManager(context, "Wave", "RaiseHand");
(ManagedNite.XnMException again).

I think the problem might be in an XML file - there are no definitions
for production nodes (wave and raise hand).

My XML:

***
<OpenNI>
<Licenses>
<License vendor="PrimeSense" key="0KOIk2JeIBYClPWVnMoRKn5cdY4"/>
</Licenses>
<Log writeToConsole="true" writeToFile="false">
<LogLevel value="3"/>
<Masks>
<Mask name="ALL" on="false"/>
</Masks>
<Dumps>
</Dumps>
</Log>
<ProductionNodes>
<Node type="Image" name="Image1">
<Configuration>
<MapOutputMode xRes="640" yRes="480" FPS="30"/>
<Mirror on="true"/>
</Configuration>
</Node>
<Node type="Depth" name="Depth1">
<Configuration>
<MapOutputMode xRes="640" yRes="480" FPS="30"/>
<Mirror on="true"/>
</Configuration>
</Node>
</ProductionNodes>
</OpenNI>
***

I triad to add nodes

<Node type="Gesture" />
<Node type="Hands" />

but then program wont pass context.Init(); again.

Thanks for your help,
Łukasz

yap same here to. in another topic about some c# extensions to the
wrapper there's a sample that works.

Łukasz,
Below is the file I'm using. One difference I see is addition of the User
node (this loads the scene analyzer).
Did check if you entered the NITE license key during installation? You can
just run the setup again to make sure.

( Btw. Did you get the email I sent you directly ?)

<OpenNI>
<Licenses>
<License vendor="PrimeSense" key=""/>

</Licenses>
<Log writeToConsole="true" writeToFile="false">

<!-- 0 - Verbose, 1 - Info, 2 - Warning, 3 - Error (default) -->

<LogLevel value="3"/>
<Masks>
<Mask name="ALL" on="false"/>
</Masks>
<Dumps>
</Dumps>
</Log>
<ProductionNodes>

<Node type="Depth">

<Configuration>
<MapOutputMode xRes="640" yRes="480" FPS="30"/>
<Mirror on="true"/>
</Configuration>
</Node>

<!--Node type="Scene" /-->
<Node type="User" />

<Node type="Gesture"/>
<Node type="Hands"/>

</ProductionNodes>
</OpenNI>

Problem solved - during NITE Installation I entered license number
without last character ('='), which I've thought wasn't part of it.
I reinstalled it with correct license and it worked.

Thanks for help.

Ok, going to prove my ignorance here :)

So, I downloaded
http://www.google.com/url?sa=D&q=http://dl.dropbox.com/u/7911268/managed%2520OpenNI.zip&usg=AFQjCNE2PyPLvbJsSN4Aru4M9WIu17NjEw

There are two project: a brand new (empty) wpf project and a console
one.

I start the console and everything works fine, except the fact that
nothing does happen.

The IR rays start to glow, and in the several times I've been running
the project, I got the sessionManager_FocusStartDetected event fired.

However, trying to wave my hand or raise them I could not get other
events fired.

The real question is: How can I get some visualization? I'd like to
put the depth camera on a wpf image, for example.

Thanks in advance for help.
