3D Point Clouds using Kinect V2. libfreenect2 used to interface with the kinect Point Cloud Library used for getting point cluds from images and visualizing using Point Cloud Library. The Frame grabber functonality is present in the Kinect2Grabber class Build the grabber/Kinect2Grabber as. grabber/Kinect2Grabber-$ mkdir build grabber/Kinect2Grabber-$ cd build && cmake .. grabber/Kinect2Grabber-$ make install. Then build the executable by using the CMakeLists.txt located in the grabber/ directory The executable links to the shared object libkinectgrabber.so generated by building Kinect2Grabber. grabber -$ sudo ./grabber.

QUESTION
I'm trying to record kinectv2 data for Image classification problem I am trying to solve. Is there any way to record the kinectv2 data?
I have tried using pickle to save the depth data, however since there is no __reduce__ method in the libfreenect2
library for the Frame class I encountered an error.
ANSWER
Answered 2019-Jul-16 at 08:47Your two options are:
Make the class pickleable. This involves editing the Cython code of libfreenect2. Probably the most viable way to do it is to add a
__reduce__
method, returning theFrame
constructor and a tuple of arguments.Just save the frame data instead - the
Frame
has anasarray
function that can get a Numpy array, and there's loads of options for saving those. This is probably the simplest approach. When you want to load it then just load the Numpy array and call the frame constructor with that.
QUESTION
We are getting joint data in JSON Objects format. The data is streaming live on the Chrome Console as you can see in the picture.
How do we take this data (from the Chrome Console) and send it over to a C# file on the computer in real-time?
From Console: JSON Object data from kinectv2
