Taking joint data from the closest player only

Question

Hello!I would like to know how i can take the data from the closest player to kinect only.i want to recognize only the first person that appears to kinect and noone else above him.How can i convert this?

 SkeletonData skeleton = (from s in allSkeletons.Skeletons
                                     where s.TrackingState == SkeletonTrackingState.Tracked
                                     select s).FirstOrDefault();

Answer 1

You can get it using Z or depth value

Please check the below code

  Skeleton[] trackedskeletons = (from skl in _skeletonData
              where skl.TrackingState == SkeletonTrackingState.Tracked                              select skl).ToArray<Skeleton>();
  Skeleton[] _skeleton;
  float depth = 0;
  foreach (Skeleton skl in trackedskeletons)
                {
                    if (depth ==0 || skl.Position.Z<depth)
                    {
                        depth = skl.Position.Z;
                        _skeleton = skl;
                        
                    }
                }

Try to send all tracked skeletons to the following method and it will get you the closest player only

private static Skeleton GetPrimarySkeleton(IEnumerable<Skeleton> skeletons)
        {
            Skeleton primarySkeleton = null;
            foreach (Skeleton skeleton in skeletons)
            {
                if (skeleton.TrackingState != SkeletonTrackingState.Tracked)
                {
                    continue;
                }

                if (primarySkeleton == null)
                    primarySkeleton = skeleton;
                else if (primarySkeleton.Position.Z > skeleton.Position.Z)
                    primarySkeleton = skeleton;
            }
            return primarySkeleton;
        }

Answer 5

@MohamedSakr

, code works great. Thanks!

I spent a night trying to do the same (get nearest player) using MS's KinectManager class, but there's no sample for using it with WinForms, only WPF sample. It would be great if someone could post an easy sample for using KinectManager class, which have option to get skeletons for most active player, sticky player etc. Would be handy in some more complex project.

For now, your code for getting the nearest player is working good for me :)
