QUESTION
Hello everyone for a university project I am working with the Kinect sensor to get a point cloud. to work with the Kinect I have installed the J4K library for processing, but when I run an example code I get the following message. How can I solve? thank you all.
...ANSWER
Answered 2021-Jun-03 at 00:17Which version of the Kinect are you using ?
Based on the error the assumption is you're planning to use Kinect v2 (for Xbox One with Windows USB adaptor). If that's the case you need to first install Kinect for Windows SDK 2.0. Make sure the Kinect drivers are properly installed and you can run the precompiled Kinect for Windows SDK 2.0 example applications.
What the error message isn't telling you is that ufdw_j4k2_64bit.dll is not loaded because it depends on Kinect20.dll (which it expects in C:\WINDOWS\System32\
where the SDK installer would place it).
If you're still having issues you can try installing Thomas Lengeling's KinectPV2 library (which you can easily do via Sketch > Import Library > Add Library > (search) Kinect v2 for Processing. It may not have the same features as the ufdw library, but the instructions are clear and you can definitely get a point cloud.
QUESTION
New to pykinect and kinect in general -- trying to simply get a count of bodies currently being tracked. No skeletal or joint data required. Just want to get a running count of bodies currently in frame. I am using a kinect-v2 and pykinect2.
Being more specific, I'm trying to track how many bodies are in frame and the time elapsed since that value changed. (0 people to 1 person, 1 person to 2, etc.) Due to the built examples for pykinect and the way that they loop, this has proven difficult however. The latest attempt (Now updated with the solved code):
...ANSWER
Answered 2021-May-13 at 07:28I found a useful snippet that does what you need within one of the examples provided in the PyKinect2 GitHub repo.
You need to get the body frame, and then count the number of tracked bodies:

QUESTION
I am processing frames received from Kinect v2 (Color and IR) in UWP. The program runs on remote machine (XBOX One S). The main goal is to get frames and write them to the disk with 30 fps for Color and IR to later process them further.
I am using the following code to check the frame rate:
...ANSWER
Answered 2021-Feb-27 at 22:26XBOX One has maximum available memory of 1 GB for Apps and 5 for Games. https://docs.microsoft.com/en-us/windows/uwp/xbox-apps/system-resource-allocation
While in PC the fps is 30 (as the memory has no such restrictions).
This causes the frame rate to drop. However, the fps did improve when running it on release mode or published to MS Store.
QUESTION
I know this sounds stupid and I'm propably very late to the party but here's the thing I want to program an gesture recogniction application (in the likes of this Hand detection or this actual finger detection) for the Xbox 360 Kinect. SDK (version 1.8) is found, installed and works, preliminary research is done - I only forgot to look in which language to write the code. The link from the SDK to the documentation would be the first thing to do but is a dead end, unfortunately.
From the provided examples it seems either to be C++ or C# although some old posts also claim Java. My question is: Is there a documentation not tied to the SDK and which pitfall are there in regard to developing in this specific case under C++/C#/Java? A post from 2011 barely covers the beginning.
Addendum: On further looking I was prompted for the Samples site from the developer toolkit - which can be reached, yet all listed and linked examples are dead ends too.
Addendum: For reference I userd this instruction - ultimately proving futile.
Found an version of NiTE here
...ANSWER
Answered 2021-Jan-19 at 22:29I've provided this answer in the past.
Personally I've used the Xbox360 sensor with OpenNI the most (because it's cross platform). Also the NITE middleware on alongside OpenNI provides some basic hand detection and even gesture detection (swipes, circle gesture, "button" push, etc.).
While OpenNI is opensource, NITE isn't so you'd be limited to what they provide.
The links you've shared use OpenCV. You can install OpenNI and compile OpenCV from source with OpenNI support. Alternatively, you can manually wrap the OpenNI frame data into an OpenCV cv::Mat
and carry on with the OpenCV operations from there.
Here's a basic example that uses OpenNI to get the depth data and passes that to OpenCV:
QUESTION
I have a dataframe that consists of of video game titles on various platforms. it contains, among other values the name, critic's average score and user's average score. Many of them are missing scores for the user, critic and/or ESRB rating.
What i'd like to do is replace the missing rating, critic and user scores with those for the same game on a different platform (assuming they exist) i'm not quite sure how to approach this.(note - i don't want to drop the duplicate names, because they aren't truly duplicate rows)
here is a sample chunk of the dataframe (i've removed some unrelated columns to make it manageable):

is what you need:
QUESTION
I am trying to run C++ code for Azure Kinect Body Tracking samples on Windows available from Microsoft on Git. I have latest NVIDIA drivers installed on my system. While trying to build the project in Visual Studio, NuGet restore for Microsoft.Azure.Kinect.BodyTracking.Dependencies.cuDNN fails for me with a message "could not find a part of path build/native/Microsoft.Azure.Kinect.BodyTracking.Dependencies.cuDNN.targets".
On the other hand, the body tracking viewer app works fine for me.
...ANSWER
Answered 2020-Nov-26 at 06:57I was able to solve this by reinstalling the Visual Studio. Not sure what was failing but it got resolved after fresh install.

QUESTION
I have Azure Kinect and I am currently using PyK4a wrapper for python and Azure Kinect SDK for C++ application. I want to use feed from my Kinect in two applications at the same time. Is it possible to do this in parallel?
...ANSWER
Answered 2020-Nov-19 at 20:58One alternative is to create a new application that reads the feed from the Kinect. This new application would then forward the feed to your two applications.

Install Kinect
Install Vrui from ~/src/Vrui-<version>-<build> (see Vrui README file).
Change into ~/src directory and unpack the Kinect 3D Video Capture Project tarball: > cd ~/src > tar xfz <download path>/Kinect-<version>.tar.gz or - > tar xf <download path>/Kinect-<version>.tar
Change into the Kinect 3D Video Capture Project’s base directory: > cd Kinect-<version>
If the Vrui version installed in step 0 was not 4.6, or Vrui’s installation directory was changed from the default of /usr/local, adapt the makefile using a text editor. Change the value of VRUI_MAKEDIR close to the beginning of the file as follows: VRUI_MAKEDIR := <Vrui install dir>/share/make Where <Vrui install dir> is the installation directory chosen in step 0. Use $(HOME) to refer to the user’s home directory instead of ~.
Build the Kinect 3D Video Capture Project: > make
Install the Kinect 3D Video Capture Project: If Vrui was installed in /usr/local or elsewhere outside the user’s home directory: > sudo make install This will ask for the user’s password to install the Kinect package inside Vrui’s installation directory. If Vrui was installed inside the user’s home directory: > make install
(Optional, Linux-only) Install a udev rule file to give access to all Kinect devices to the user currently logged in to the computer’s physical console. Read below for details. > sudo make installudevrules This will ask for the user’s password to copy the rule file, 69-Kinect.rules, into the udev rule directory /etc/udev/rules.d.
