You could connect the signal output of the Skeleton block to a "To workspace" Simulink block. This will save the output of your simulation to your current MATLAB workspace. You can then access joint data as a 20x3xN matrix (where N is the number of frames in your simulation and assuming you are using the Windows kinect runtime).
I'm trying the latest version with an Asus Xtion Pro Live, but the NID Skeleton block always causes MATLAB to crash. The depth and video blocks work fine however, and everything works fine with a Kinect.
I am using the kinect simulink blocks from the library together with a real time synchronization. The real time Synchronization block is constantly missing ticks and when looking at the profiler report, the reason is that the NID IMAQ block uses all its sample time, as if it is idling and waiting for the next image. This happens at 0.04 s as well as 0.2 s or more.
Do you know how this time can be set free for other calculations to be done?
Thank you in advance,
"video viewer" and "frame rate display" are blocks in Computer Vision System Toolbox™. Simulink support for Kinect works without the toolbox, so if it is annoying, you can remove the blocks.
