Hello!
Today’s post is simple: let’s see how to make a Hello World app with the new SDK v2. In Kinect apps, Hello World is basically an app that detects a person in front of the Kinect sensor.
So let’s go for it
1. Create a console app
2. Add the reference to Microsoft.Kinect v2.0
4. Important: Change the settings for the reference to not make a local copy.
5 Modify the project so that it is compiled for X 86 or X 64. In this way still do not work projects with the ANY CPU type build.
6. Then add the following code to the console app
1: using System;
2: using Microsoft.Kinect;
3:
4: namespace ConsoleApplication1
5: {
6: class Program
7: {
8: private static KinectSensor _kinectSensor;
9: private static Body[] _bodies;
10: private static BodyFrameReader _bodyFrameReader;
11:
12: static void Main(string[] args)
13: {
14: // gets the default sensor
15: _kinectSensor = KinectSensor.Default;
16: if (null != _kinectSensor)
17: {
18: // open the sensor
19: _kinectSensor.Open();
20:
21: // init body recognition
22: _bodies = new Body[_kinectSensor.BodyFrameSource.BodyCount];
23: _bodyFrameReader = _kinectSensor.BodyFrameSource.OpenReader();
24: _bodyFrameReader.FrameArrived += _bodyFrameReader_FrameArrived;
25:
26: // sensor init done!
27: Console.WriteLine("Sensor init done !");
28: }
29:
30: Console.ReadLine();
31: }
32:
33: static void _bodyFrameReader_FrameArrived(object sender, BodyFrameArrivedEventArgs e)
34: {
35: var frameReference = e.FrameReference;
36: var frame = frameReference.AcquireFrame();
37: if (frame == null) return;
38: using (frame)
39: {
40: // update bodycount
41: frame.GetAndRefreshBodyData(_bodies);
42: foreach (var body in _bodies)
43: {
44: if (body.IsTracked)
45: {
46: Console.WriteLine("Body Tracked:" + body.TrackingId);
47: }
48: }
49: }
50: }
51: }
52: }
Let see some interesting notes for the new SDK
- line 15. We can have access to the sensor by default connected to our computer.
- lines 21 to 24; now introduces the concept of Body for recognition. Formerly they were Skeletons
- lines 33 to 50; Once detected a frame of Body, we can parse it and complete an array of bodies to begin to work with them
7. Launch the app KinectService
8 Run the application, and we already have an app that detects bodies with the new Kinect for Windows SDK v2.
And as always
“This is preliminary software and/or hardware and APIs are preliminary and subject to change“
