kinect

The image produced by the color and depth sensor on the Kinect are slightly out of alignment. How can I transform them to make them line up? The key to this is the call to 'Runtime.NuiCamera.GetColorPixelCoordinatesFromDepthPixel' Here is an extension method for the Runtime class. It returns a WriteableBitmap object. This WriteableBitmap is automatically updated as new frames come in. So the usage of it is really simple: kinect = new Runtime(); kinect.Initialize(RuntimeOptions.UseColor | RuntimeOptions.UseSkeletalTracking | RuntimeOptions.UseDepthAndPlayerIndex); kinect.DepthStream.Open

Lately I have been working on trying facial recognition with the Kinect, using the new Developer Toolkit (v1.5.1). The API for the FaceTracking tools can be found here: http://msdn.microsoft.com/en-us/library/jj130970.aspx . Basically what I have tried to do so far is attain a "facial signature" unique to each person. To do this, I referenced these facial points the Kinect tracks: ( ) . Then I tracked my face (plus a couple friends) and calculated the distance between points 39 and 8 using basic algebra. I also attained the values for the current depth of the head. Heres a sample of the data I

I'm using the Microsoft Kinect SDK to get the depth and color information from a Kinect and then convert that information into a point cloud. I need the depth information to be in real world coordinates with the centre of the camera as the origin. I've seen a number of conversion functions but these are apparently for OpenNI and non-Microsoft drivers. I've read that the depth information coming from the Kinect is already in millimetres, and is contained in the 11bits... or something. How do I convert this bit information into real world coordinates that I can use? Thanks in advance! This is

I am considering using Kinect in one my projects, but I am totally lost between all the libraries. Don't know what is what exactly. Most importantly I am reading stuff about OpenNI and OpenKinect. But don't know their relation/differences. PS. I am using Ubuntu or Mac. OpenKinect is a community of people, not a library. The OpenKinect community releases the libfreenect Kinect driver. libfreenect and OpenNI+SensorKinect are two competing, opensource libraries/drivers. libfreenect (Apache 2.0 or GPLv2) derives from the initial, reverse-engineered/hacked Kinect driver whereas OpenNI+SensorKinect

i want to map an ellipse to the hand joint.And the ellipse has to move as my hand joint will move. Please provide me some reference links that help me in doing programs using kinect Sdk 1.5. Thank you Although what @Heisenbug would work, there is a much simpler way in WPF. You can find a tutorial on it at Channel 9's Skeleton Fundamentals . Basically you need a Canvas, and however many ellipses you want. Here is the code XAML <Window x:Class="SkeletalTracking.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

I'm working on a WPF Kinect project. It's one of the developer toolkit samples of Windows Kinect and it's called "Kinect Explorer". You can download it from the Kinect Developer Toolkit SDK ver 1.5. In kinectwindow.xaml I added a button and a checkbox. Also, there is a class called kinectskeleton.cs in which I created two DataTables and a boolean variables. The first DataTable is filled in the OnRender function while the other is empty. The boolean variable is set by default to false. So, what I want is when the button in the kinectwindow.xaml.cs is pressed the latest data in the filled

I just want to be able to do something when my skeletal joint (x,y,z) coordinates are over the x,y,z coordinates of the button . . I have the following code but somehow it doesnt work properly . .as soon as my hand moves it will do something without my hand reaching the button if (skeletonFrame != null) { //int skeletonSlot = 0; Skeleton[] skeletonData = new Skeleton[skeletonFrame.SkeletonArrayLength]; skeletonFrame.CopySkeletonDataTo(skeletonData); Skeleton playerSkeleton = (from s in skeletonData where s.TrackingState == SkeletonTrackingState.Tracked select s).FirstOrDefault(); if
