Real time skeleton tracking using kinect v2

I'm trying to use this code using kinect v2 to get real time skeleton tracking. I'm using matlab R2018a.

clear; close all;clc
imaqreset;

depthVid = videoinput('kinect',2);

triggerconfig (depthVid,'manual');
framesPerTrig = 1;
depthVid.FramesPerTrigger = framesPerTrig;
depthVid.TriggerRepeat = inf;

prop = getselectedsource(depthVid);
prop.EnableBodyTracking = 'on';
start(depthVid)

himg = figure;
while ishandle(himg);
    trigger(depthVid)
    [frameDataDepth, timeDataDepth, metaDataDepth] = getdata(depthVid)
    if  sum(metaDataDepth.IsBodyTracked) > 0
        skeletonJoints = metaDataDepth.JointPositions(:,:,metaDataDepth.IsBodyTracked)
        try
            delete(h)
        end
        h = plot(skeletonJoints(:,1), skeletonJoints(:,2),'.','MarkerSize',15); % Plota no imshow as juntas
        axis([-2.1 2.1 -2.1 2.1])
    end
end

This code does work, but it has a big delay, when i used:

tic
trigger(depthVid)
toc

The elapsed time is 1.002209 seconds

The trigger made my code runing slow, how can i fix it? Is there a way to reduce trigger time? The FPS are very slow.

Notice that the elapsed time to trigger is big (1sec) just when i enable body tracking (i need to use it, since i want to get real time skeleton tracking). When i tried without using body tracking property the trigger time was arround 0.003 seconds, the idial for the application.

Thank you!

Hi Robert!

Did you managed to solve your problem? I am facing a similar problem, the trigger of the depth Video takes too long. Any tips?

Thanks!

Hey did you fixed it? I'm having a similar issue, there's a gap betwene the RGB image and the skeleton

[prasanth s]

can you attach the input video 'depthVid'?

[Alessandra Martinez]

I don't have a saved input video. I'm trying to make it real time, however the RGB image isn't synched with the plotted skeleton. I'm using imshow() though.

I could attach the code I'm working with.
