kinect

Given two consecutive 3D point clouds 1 and 2 (not the whole cloud, say 100 points selected from the cloud with OpenCV's GoodFeaturesToMatch), obtained from a Kinect depthmap, I want to compute camera's homography from 1 to 2. I understand that this a projective transform, and it has already been done by many people: here (slide 12) , here (slide 30) and here in what seems to be the classic paper . My problem is that whilst I'm a competent programmer, I haven't got the math or trig skills to turn one of those methods into code. As this is not an easy problem, I offer a large bounty for the

I'm working in wpf application i made a checkbox in the XAML, then my code calls a function in a class and in this function there is an if condition where its checking on whether the checkbox is checked or not but the checkbox is not seen in this class, so how to do this? Many thanks EDIT: Here is the steps I did: i created the ViewModel class under the same project of KinectSkeleton as shown: ViewModel class: public class ViewModel { public bool IsChecked { get; set; } public bool is_clicked { get; set; } } and in the KinectSkeleton I defined a property as shown: public static readonly

I am making a program with the SDK, where when users are detected, The program draws a skeleton for them to follow. I recently saw a game advertised on my Xbox, Nike+ Kinect and saw how it displays a copy of the character doing something else like: http://www.swaggerseek.com/wp-content/uploads/2012/06/fcb69__xboxkinect1.jpg Or http://www.swaggerseek.com/wp-content/uploads/2012/06/fcb69__xboxkinect.jpg Can I create a point-cloud representation of the only the person detected (not any of the background)? Thanks in advance! EDIT Using this site , I can create point clouds, but still can't crop

Microsoft has recently released Kinect SDK 1.5 and some very neat associated features such as face tracking. I have a Kinect sensor for XBox 360 and Windows 7 (driver, Kinect studio) do not seem to recognize the device. Can anyone advise if this is an "operator error" or if SDK 1.5 indeed does not support Kinect for XBox sensor but only Kinect for Windows (I have USB and power adapter for it). Thank you, Edmon As Chris Ortner pointed out, the Kinect for Xbox sensor is compatible with Windows 7 for development purposes only - you need to have the SDK installed. It might be worth checking to see

I have Kinect and drivers for Windows and MacOSX. Are there any examples of gesture recognitions streamed from Kinect using OpenCV API? I'm trying to achieve similar to DaVinci prototype on Xbox Kinect but in Windows and MacOSX. I think it wont be this simple mainly because the depth image data from kinect is not so sensitive. So after a distance of 1m to 1.5m all the fingers will be merged and hence you wont be able to get a clear contours to detect the fingers The demo from your link doesn't seem to use real gesture recognition. It just distinguishes between two different hand positions

I'm a student from Nanyang Technological University (NTU), Singapore. And currently developing a project using Kinect SDK. And my question is, anyone know how to develop a program to detect a finger (or fingertip) using Kinect SDK, or maybe even some possible reference codes. Anyway, I also tried to search on google, but the only reference I got is using Open NI, instead of Kinect SDK. Thanks and Regards I was looking into that myself, although haven't gone deep into it. OpenNI has some constants for finger tip/wrist detection, but that's not implemented yet, but that's not an option for your

I'm new about opencv(c++) and kinect. I try to take a video image with c++ from kinect. I search everywhere but I didn't find anything. Because people are made using openNI or OpenKinect. I don't want to use this lib. How can I do it?? Thanks!!! You could use the kinect for windows SDK to grab the frames, and then convert them to an opencv format. See this code example which does that in visual studio (found in this thread on the microsoft forums), unfortunately I don't have a kinect right now to test the code: #include "stdafx.h" #define COLOR_WIDTH 640 #define COLOR_HIGHT 480 #define DEPTH

is it possible to construct a 3d model of a still object if various images along with depth data was gathered from various angles, what I was thinking was have a sort of a circular conveyor belt where a kinect would be placed and the conveyor belt while the real object that is to be reconstructed in 3d space sits in the middle. The conveyor belt thereafter rotates around the image in a circle and lots of images are captured (perhaps 10 image per second) which would allow the kinect to catch an image from every angle including the depth data, theoretically this is possible. The model would also
