ERROR: Can not create OpenNI depth generator (OpenNI Status: Can’t create any node of the requested type!)

[Kano]

Hi,

I’m using a Intel Realsense D415 and I try to use Nuitrack to achieve Skeleton Tracking.
I followed instructions and configured everything as requested, then I try to run nuitrack_c11_sample.exe.
Here is the error message I get :

Start nuitrack c11
ERROR: AstraProPerseeDepthProvider can’t create RGB Stream (VideoCapture device ID is not valid)
DepthProviderManager: AstraProPerseeDepthProvider can’t create RGB Stream (VideoCapture device ID is not valid)
Can’t find video camera!
Can’t find Depth camera!
ERROR: Couldn’t open device ( DeviceOpen using default: no devices found

DepthProviderManager: Can not create OpenNI depth generator (OpenNI Status: Can’t create any node of the requested type!)

Note that depth is well displayed by Nuitrack despite this error.

This topic mentioned the same error, without providing any solution :

1.3.3 and Intel d435

HI Olga, No we still have ongoing issues with D435. There is some sort of bug it seems in the latest intel drivers and windows 10. There are a number of people in the intel forums with similar issues. Still waiting for a full response from Intel. Basically, the INTEL driver for Firmware updater is not functional. When you attempt to update the D435 using the intel DFU it fails. The same issue exists in the intel windows universal driver on windows 10 since this driver installs a RS400 servi…

I have done some search and it looks like the problem could come from NITE :

I tried to install it, but I still get the same error …

Thanks for your help,

They are NOT errors - just ignore them - its a set of diagnostics that show how nuitrack attempts to find a sensor to connect to - if it doesnt find a sensor type shows a message for that type - it keeps doing this till it finds a sensor type that its happy with.

Hi Westa, thank you for your answer.

If there are no errors, the executable “nuitrack_c11_sample.exe” should track my body, isn’t it ? Actually, I can only see the depth of the camera, nothing else happens …

Moreover, I tested the “NuiTrack SDK Sample Program” (http://unanancyowen.com/en/nuitrack-sdk-samples/)
supposed to provide functions of hand-tracking and skeleton-tracking. But this time, only the RGB stream is displayed (with the same error message).

TL;DR : Is there a way to check if Nuitrack works correctly with my Intel Realsense D415 by displaying body tracking ?

Hi Kano,

FWIW - Stand up and step back at least a meter - the system is showing you the depth data from the intelsensor as a greyscale map.

For nuitrack to operate correctly - please look at the setup details in the documentation. It shows the optimum position for the sensor - which is roughly 1.5m.

Until you are in an optimum position - nuitrack will struggle to show any skeleton - the way the system works is by analyzing the depth data - and using AI style recognition systems to find what looks like a human body.
