Demo: How to get skeleton data

Kinect For Windows SDK & Toolkit Download SDK & Toolkit: http://www.microsoft.com/en-us/kinectforwindows/ Install SDK & Toolkit. Install examples provided in toolkit (SkeletonBasics-WPF)

4 Steps to Get Skeleton Data Find an available Kinect sensor. Enable skeleton data stream. Register stream ready event handler function. Start capturing data.

4 Steps to Get Skeleton Data – Find an available Kinect Sensor KinectSensor object represents a Kinect sensor entity. Enumerate all Kinect sensors and find a usable one. foreach (var potentialSensor in KinectSensor.KinectSensors) { if (potentialSensor.Status == KinectStatus.Connected) this.sensor = potentialSensor; break; }

4 Steps to Get Skeleton Data – Find an available Kinect Sensor Status of Kinect sensor: Disconnected – Sensor has been plugged off USB port. Connected – Sensor is ready to use. Initializing – Sensor is being initialized. Not powered – Sensor is connected to USB port but power line is disconnected.

4 Steps to Get Skeleton Data – Enable skeleton data stream KinectSensor.SkeletonStream implements API functions related to skeleton data retrieving and processing. Initialize to enable skeleton data stream: this.sensor.SkeletonStream.Enable();

4 Steps to Get Skeleton Data – Register stream ready event handler function Register the stream event handler function to Kinect sensor so that when a new skeleton frame comes in, the handler function is called to retrieve and process the data. this.sensor.SkeletonFrameReady += this.SensorSkeletonFrameReady;

4 Steps to Get Skeleton Data – Start Kinect sensor Call KienctSensor.Start() to let Kinect sensor begin capturing the data. try { this.sensor.Start(); } catch (IOException) this.sensor = null;

Retrieve Skeleton Data When new incoming data frame is ready, stream data ready event is triggered. Open image frame in stream data ready event handler function. private void SensorSkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e) { using (SkeletonFrame skeletonFrame = e.OpenSkeletonFrame()) if (skeletonFrame != null) skeletons = new Skeleton[skeletonFrame.SkeletonArrayLength]; skeletonFrame.CopySkeletonDataTo(skeletons); }

Skeleton Data Joints – Collection of 20 joints which have the coordinate information. Position – Position of tracked human body. TrackingState – If all 20 joints are tracked or only position is provided. ClippedEdges – If any joints are outside capture range. Each joint can have tracked, not tracked or inferred state.
