Kinect Depth calculation [closed]
Sorry guys, i am desperate for answer. That is why i didn't follow the rules of this website. I sincerly apologise. For this code, i have come up with a better one. float cx = 320.0; float cy = 240.0; float minDistance = -10; float scaleFactor = 0.0021;
for (int v=0, n=0 ; v<480 ; v++)
{
for (int u=0 ; u<640 ; u++, n++)
{
Vec3f result;
result.x = float(((u - cx) * t_gamma[depth[n]]+ minDistance) * scaleFactor * (cx/cy));
result.y = float(((v - cy) * t_gamma[depth[n]]+ minDistance) * scaleFactor);
result.z = float(t_gamma[depth[n]]);
}
}
// OS X requires GLUT to run on the main thread
gl_threadfunc(NULL);
return 0;
} is this code better? i have tried to save the depth data but all the data is zero. I don't know where is the problem?

Why do you want to do this yourself? Is it an exercise or are you interested in the results. For the latter I would highly recommend using the openni_camera node as it already gives your 3D data.

I am an intern in a company and i was asked to do this... Using the OpenKinect.

If your depth data is zero, the code above is probably not the problem. Does OpenKinect provide samples? Then use those, otherwise you can still use the ROS node, remove the ROS stuff and use it for yourself (respecting the license of course).
