nuitrack-sdk's Issues

Nuitrack_ARM64.apk v0.35.9 and UI problem not allowing license input

After App installation, I can see the loading bar with progress. But the Nuitrack Logo stretches together with the loading bar, displacing all other components. I miss the input for license and the selection

nuitrack_v0.35.9_not_working.mov

for devices.
This is happening with v0.35.8 as well. I had to roll back to v0.35.7

This repository is over its data quota

Error while activating the SDK

Hello and thank you for this great SDK.
But i have one problem while use the activation tool, when i i use activation_tool/Nuitrack.exe it just doesn't lunch, i checked the event viewer it showed that there is dll problems. First there was the libstdc++-6.dll, so i downloaded it and copy it to the folder, and again when i try to lunch the activation tool it doesn't do anything, and then i checked the event viewer and it showed that there was an error with ntdll.dll from /windows/system32.
My platform is win 10 64bit.
I would like to get help on this issue, because i am unable to use the SDK in any unity project.
And thank you.

Terminate Exception unity

I know there has already been an issue on this topic here, but the solution given did not fix our error. We copied the tbb.dll file, we tried different versions of the SDK and we made sure that echo %NUITRACK_HOME% returns the right path (in my case C:\Program Files\Nuitrack\nuitrack\nuitrack). All that done, yet we still face the error :
TerminateException: NuitrackException (TerminateException)

Any help would be awesome, thanks in advance :)

Azure Kinect DK nuitrack.config isn't applying

Model: Azure Kinect DK (AzureKinectDepthProvider)
Tested the config in nuitrack application and Unity Render Texture

In unity my kinect isn't changing the RGB width and height it stays natively 640x480

Everything works for my "Intel RealSense D455(Realsense2DepthProvider)"

note: I even tried different names like "AzureKinectDepthProvider", "AzureKinectDKDepthProvider"

Firmware and unity sdk is the latest

Missing documentation about the daemon

I am unable to find any documentation on how to use the Nuitrack Daemon

Unity3D plugin scripts not working on Ubuntu 20.

Hi,
I followed the instructions [here] (https://download.3divi.com/Nuitrack/doc/UnityBasic_page.html) for setting up the nuitrack Unity demo.
When I drag the NuitrackScripts prefab in the scene, the inspector give for each of the scripts the warning : 'The associated script can not loaded, Please fix any compîle errors'.
I am rather a newbie to Unity. Is there something obvious I am missing? Has somebody else experienced this problem.
Many thanks

Uninstallation stuck at 33%

I want to uninstall Nuitrack 0.35.9 in order to update to a newer version, but the uninstaller gets stuck at 33%. The detail window remains completely empty. How do I get rid of it? I could remove the directory and the environment variables, but I want to get rid of it from my Apps & Features as well.

Can i apply your code to my desktop

Hi, first of all great work ! I wanted to know if it's possible to use your code to devellope a touchless UI on my computer ? The goal being to be able to rigth/left click and move the mouse around on my pc in general.

$NUITRACK_HOME/qt/lib/fonts missing in latest nuitrack-ubuntu-amd64.deb

The nuitrack shell script sets QT_QPA_FONTDIR=$NUITRACK_HOME/qt/lib/fonts/ however the fonts directory is missing in the latest nuitrack-ubuntu-amd64.deb package. Not sure if this is relevant to issue #24.

Jittery Results in Unity SDK

I have used all tutorials and the results are nowhere near the NUITrack platform executable. The skeleton bones keep on disappearing even when staying still. However, when I run the executable and test from there, the results are smooth. (using RealSense D455)

What can be the reason?

Unity3D and Android on Persee/TVico crash

Scenario

I am using the Orbbec Persee/TVico camera to stream color and skeleton frames on an Android app.

I've purchased a license and then followed the steps in your Wireless case documentation to setup the Persee device. Persee is properly running as a WiFi hotspot.

Also, I downloaded the VicoVR.apk and assigned the proper IP address, exactly as described in your Android section. When I open the "Test Sensor" screen on the VicoVR app, everything works fine.

The issue

I downloaded the latest Unity package from your repository. When I build a Unity app for Android, the app is crashing on Android. Here's how to reproduce:

• Create a new Unity project and import the Nuitrack Unity package. Also, the Unity installation folder includes the proper tbb.dll.
• Open NuitrackManager.cs and assign the correct IP address of the Persee camera.
• Open the RGBandSkeletons Unity scene (or any other built-in scene).
• In the NuitrackScripts, set the Wifi Connect option to TVico (also tried with VicoVR).
• Run in the Editor - works OK.
• Build for Android and run.
• The application starts, displays the Unity logo, and immediately crashes.

Here's the output of the Android Logcat:

nuitrack.ModuleNotInitializedException
   at nuitrack.Nuitrack.Update ()
   at NuitrackManager.Update ()

Notes

• Tried on 2 different Android phones.
• The Persee camera, Windows computer, and Android device are all connected to the same network.
• I've used the Nuitrack/Auto switch dll option.
• I've tried to set the Persee as a WiFi hotspot and as a Portable hotspot, leaving the default IP address. Same behavior.
• Additionally, I've tried various Unity packages from the repo History. Same behavior.

Nuitrack activation tool does not support desktop scaling

My desktop is set to 150% scaling. Some text scales up, but the layout is not adjusted.

How to use the CPU MaxLoad value in the Nuitrack.config file?

Discussed in #50

^{Originally posted by emanuelgollob September 24, 2022}
Hello everyone,
I use the Nuitrack C# sample with the AI skeleton tracker and would like to limit the maximum CPU usage.
I found this setting in the nuitrack.config but couldn´t find any explanation for it:

"CPU": {
    "MaxLoad": -1.0
},

I guess -1.0 means no restriction at all, but how could I set it to, e.g. 60% of my maximum CPU power?

Thank you!

L515 not working in Unity 0.34.1 (at least for me)

I have an Intel Lidar L515 sensor and when I try the demos of NuiTrack for Unity (for instance the BasicSkeleton demo) I get a ModuleNotInitializationException. It does not recognise the device.

I am using the latest version of the Unity package (0.34.1) on Unity 2019.4.13f1. I use a USB3 port.
NuiTrack demos work fine with an Intel RealSense 435i.
The Intel L515 works with the RealSense Viewer of Intel RealSense SDK, but it does not work using NuiTrack.
As the 0.34.1 is a very recent version, I wonder if there is a bug, because the 0.34.1 is expected to support the L515.

Administrator rights needed for Astra+ support

We tried out the Orbbec Astra+ support of Nuitrack version 0.35.12 today. We tested this on a machine with Windows 8.1, the lower compatibility bar for our products. None of the samples work when run as a normal user. The nuitrack_sample.exe program for instance exits with the following error:

WARNING: OpenNI2DepthProvider can't create RGB Stream
Create DepthProvider: OpenNI2DepthProvider
Access is denied.
terminate called after throwing an instance of 'boost::interprocess::interprocess_exception'
  what():  Access is denied.

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

They do work when you start them as administrator. The same is true for our application using the Nuitrack SDK. This is different from the Orbbec Astra and Orbbec Astra Pro which can be used in normal user mode. Having to run our applications as administrator is undesirable. Is there something I might have configured wrongly or is there a way to mitigate the problem.

This may be a Windows 8.1 specific problem, because I don't have this issue on my development computer that is running Windows 10 x64 version 21H1.

Unity keeps warning you to update tbb.dll even if it has already been replaced.

In the troubleshooting document, the following is mentioned regarding tbb.dll:

Replace the TBB library in your Unity editor with the library from Nuitrack:
Windows: copy the tbb.dll library from %NUITRACK_HOME%/bin to your Unity editor folder (for example, C:\Program Files\Unity\Hub\Editor\2019.4.8f1\Editor)

This is not enough. You will keep getting a warning that you need to replace tbb.dll when opening the project in Unity. If you accept and restart, the message will pop up again. You need to manually add a file called "tbb_backup.dll" to the same folder for the messages to cease.

This happens on version 0.35.12 with the corresponding Unity package, in unity 2020.3.12f1.

joint parameter orientation

Hi,
What is the orientation parameter mean in skeleton? It returns 3x3 matrix. Is there any relationship between real or projection values and orientation matrix? What and how can I use the orientation matrix?
Thank you.

Note: I'm using Python API.

Implementing HandsInput on unity-webview

Hello, first thank you for this tutorial it's very helpful but instead of a gallery I'm using a WebView that displays a webpage (Google Earth globe). I'm being able to move the two hand pointers on the canvas but Mouse, Move, Drag processes are not working on the WebView, what seems to be the problem? Aren't the pointers acting as a mouse already? And aren't the OnClick events of a webpage already implemented ? I would love a small guide on how to achieve this solution. I've added a screenshot of my project's architecture. Thank you!

Segmentation Fault

Hi, I am new to the nuitrack-sdk

I followed the installation instructions to install nuitrack sdk on ubuntu 20.04 however after I installed and run nuitrack on terminal I get this error:

Jittery hand tracking

Hi all! so I have followed the tutorial and when I get up to step 11 (two hand sprits moving on the background accordingly to my hand movements) and it works! However, there is some jitteriness to it all. from time to time the sprits have spasms and if I am too carless in my movements, it becomes quite hard to use. My co-worker advised that lowering the min velocity interactive point, which did help a bit. But is there an ideal set up for the camera or a configuration that I missed? The gifs in the tutorial seem to show a user much less constrained in his movements.
An other issue is that the sprites seem to stick to the sides of the screen, as if it is where they are most stable..

I am using the D435 for reference.
Thanks and have a nice day!

Failed to import package with error: Couldn't decompress package

Please provide packages (or other means for installing) for RPM-based distributions such as Fedora

It's great that you provide a .deb package for Ubuntu.
However, it would be even better if you also provided an RPM for linux user on other distributions, such as Fedora, OpenSuse, Arch etc. A generic tarball could be used for any distribution.

tbb.dll error when starting up the project with Unity ver 2020.3.24f1

When I try to start unity project with nuitrack package on Unity 2020.3.24f1,
I get message saying...
"You need to replace the tbb.dll file in editor with nuitrack compatible tbb.dll file..."
I replaced the tbb.dll file with the one in the Nuitrack bin folder, and still getting the same error message.
I also did uninstall and install the nuitrack and unity several time but still the same result.

Then I changed to unity ver 2020.3.0f1.
and followed the same steps as above and worked perfectly...

Which version of Unity is the latest supported version?

Garbage collection leak on Nuitrack.NET 0.30

Last year I reported in nuitrack forums issue 924 about Nuitrack.net creating new large arrays for every new frame, which made the GC to trigger a garbage collection every few frames.

I provided a solution, and Nuitrack was kind enough to send us a private library which had this problem solved.

We've upgraded to Nuitrack 0.30, which requires a new Nuitrack.NET dll, and after trying it, we've discovered it still has the same garbage collection problem from a year ago.

I can't understand why, a bug that was reported, aknowledged and FIXED is still not being released to the public.

Please, fix it ASAP and release a new nuitrack.NET dll immediately.

Terminate Exception I got an issue with Unity

LibYAML Conflict

On Ubuntu 18.04, Nuitrack seems to coexist fine with other applications, but on Ubuntu 20.04 I am noticing undefined symbols due to Nuitrack's version of libyaml-cpp overriding the system default at /lib/x86_64-linux-gnu/libyaml-cpp.so.0.6. Is there a reason nuitrack must ship its own version rather than using the system default? Any workarounds to get other applications working again?

WIN10 Video Source Selection Window at C# Example Start

Hello there, I am using the Nuitrack SDK C# Example with a Nuitrack AI license on a WIN10 PC with a Intel Realsense D455 and I would like to start it automatically with every reboot.

It works occasionally but very often a WIN10 video source selection window appears and I manually have to choose between the Intel Realsense D455 depth or RGB camera - which is quite annoying as it ideally should reboot without any manual input.

If there is any way to avoiding this window please let me know.
Cheers

Object detection not working

Hi,
I'm trying to get Object detection working for a project.
The camera is a Realsens D435 and the platform is windows 10.
With the nuitrack activation tool, I have activated an AI license for the camera, and the test samples work - unless I check the "AI: Object Detecion", then it opens a window and immediately closes it again, with the following message in the box:

Starting test...
    3D sensor serial number: 215322076948
    3D sensor provider name: Realsense2DepthProvider
ERROR: Sample failed. Exit code: 3

Unckecking the AI: Object Detection box, it works as expected

As detailed in the online docs, I have installed Cuda 9

C:\Users\Playground>nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Sep__1_21:08:32_Central_Daylight_Time_2017
Cuda compilation tools, release 9.0, V9.0.176

The PC has a NVIDIA GeForce RTX 2060 with latest drivers installed.

I have tried installing an older version of Nuitrack (v0.35), with the same results. I intended to install v0.34, as that is th version used in the video above, but executables for older versions are not available.

Any ideas?

tbb.dll error

---

You need to replace the tbb.dll file in Editor with Nuitrack compatible tbb.dll file.
If you click [Yes] the editor will be restarted and the file will be replaced automatically
(old tbb-file will be renamed to tbb_backup.dll)

---

When I add the Unity package to the Unity project, it tells me to replace tbbdll.
If I click Yes, it keeps telling me to replace it, and I press Yes endlessly.

Unity project cycled on and off.
Also endlessly telling me to replace tbbdll.

I followed the installation order of nuitrack-sdk/Unity3D/README.md.

1. Platforms/nuitrack-windows-x64.exe
2. Unity3D/NuitrackSDK.unitypackage

I also copied and replaced tbbdll from nuitrack/bin.

nuitrack\bin\nuitrack_sample.exe. This works.

• windows 10
• unity version 2020.3.14f1, 2020.3.23f1, 2020.3.0f1
• Nuitrack v0.35.12

How can I solve this?

hello, I can't run any exe successed in "nuitrack\bin" when I use orbbec astra+ just like the white one in web https://developer.orbbec.com.cn/module.html.

and I check orbbec SDK at https://developer.orbbec.com.cn/download.html?id=77, the official "OpenNI_SDK" is not support astra+, only "orbbec_SDK" support astra+.

and I see there are "orbbec.dll"/"OniFile.dll" in floder "nuitrack\bin\OpenNI2\Drivers", these dll is in orbbec OpenNI_2.3.0.81.zip which is download from orbbec web. and I use "OpenNI_2.3.0.81\Win64-Release\tools\NiViewer\NiViewer.exe" can't open camera either.

so I'm doubt that nuitrack is really support astra+, is that only support astra pro?@https://nuitrack.com/#sensors

i push my error, there is "AstraProPerseeDepthProvider: Can't open device (" in image, but no info about astra+ or astraplus

Is it possible to pass video & depth data directly to the SDK, i.e. from a custom device?

I understand that the SDK has support for multiple devices. If I have an unsupported device, can I pass depth & color data frame-by-frame to the SDK manually? i.e. can I implement some device interface myself?

Segmentation Fault on Ubuntu 20.04

I installed the latest SDK and get a segmentation fault when trying to run the license tool. I am using a D435 sensor which works fine with realsense-viewer. Also the examples in the realsense SDK work.

When running /usr/bin/QtNuitrackLicense with gdb I get the following:

I can’t determine from this what the problem is. Can anyone offer suggestions what to try. Also if I set QT_DEBUG_PLUGINS=1 and run /usr/bin/nuitrack I get the following ( just posting the last few lines) . At the bottom is the seg fault.

I've asked for help on the forum but no luck. Hoping I can find some support here.

Missing UNITY_ANDROID in NuitrackManager.cs

There is a bug in NuitrackManager.cs in the Unity plugin.
In line num. 195, instead of if UNITY_IOS, it should be:

# if UNITY_IOS || UNITY_ANDROID
   	if (wifiConnect == WifiConnect.VicoVR)
   	{
   		nuitrack.Nuitrack.Init("", nuitrack.Nuitrack.NuitrackMode.DEBUG);

This led to some problems while using the plugin for my Android application (Nuitrack wasn't correctly identifying the platform, and thus it tried to load the Windows .dll files, which obviously weren't installed).

I suggest updating the Unity examples/tutorials, since all of them require some tweaking or modifying code before being usable. Still I haven't managed to make the SegmentExample to work.

Not support RealSense D455 ?

Does nuitrack-sdk not support realsense D455?
