Page 4 | Microsoft 4 Steps to Get Depth Data Find an available Kinect sensor. Enable depth data stream. Register stream ready event handler function. Start capturing data.

Page 5 | Microsoft 4 Steps to Get Depth 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; }

Page 6 | Microsoft 4 Steps to Get Depth 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.

Page 7 | Microsoft 4 Steps to Get Depth Data – Enable depth data stream KinectSensor.DepthStream implements API functions related to depth data retrieving and processing. Initialize to enable depth data stream: this.sensor.DepthStream.Enable(DepthImageFormat.Resolution640x480Fps30);

Page 8 | Microsoft 4 Steps to Get Depth Data – Register Stream Ready Event Handler Function Register the stream event handler function to Kinect sensor so that when a new depth frame comes in, the handler function is called to retrieve and process the data. this.sensor.DepthFrameReady += this.SensorDepthFrameReady;

Page 9 | Microsoft 4 Steps to Get Depth Data – Start Kinect sensor Call KienctSensor.Start() to let Kinect sensor begin capturing the data. try { this.sensor.Start(); } catch (IOException) { this.sensor = null; }

Page 10 | Microsoft Retrieve depth 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 SensorDepthFrameReady(object sender, DepthImageFrameReadyEventArgs e) { using (DepthImageFrame depthFrame = e.OpenDepthImageFrame()) { if (depthFrame != null) { // Copy the pixel data from the image to a temporary array dpethFrame.CopyDepthImagePixelDataTo(this.depthPixels); // Do whatever you need to do with the depth data }

Page 11 | Microsoft Depth Pixel In each pixel, there are 2 kinds of important information: Depth – The distance in millimeters between the detected objects and the sensor. This information is presented in a “short” type value. Player Index – If Kinect successfully detected a human, it assigns an index number to the pixels which belong to the person (called player). Kinect can trace up to 6 players so valid player index is ranged from 1 to 6. 0 is assigned to indicate the pixel does not belong to any player. This information is also presented in a “short” type value.
