kinect

I have calculated the intrinsic and extrinsic parameters of the camera with OpenCV. Now, I want to calculate world coordinates (x,y,z) from screen coordinates (u,v). How I do this? N.B. as I use the kinect, I already know the z coordinate. Any help is much appreciated. Thanks! First to understand how you calculate it, it would help you if you read some things about the pinhole camera model and simple perspective projection. For a quick glimpse, check this . I'll try to update with more. So, let's start by the opposite which describes how a camera works: project a 3d point in the world

I have collected data using Kinect v2 sensor and I have a depth map together with its corresponding RGB image. I also calibrated the sensor and obtained the rotation and translation matrix between the Depth camera and RGB camera. So I was able to reproject the depth values on the RGB image and they match. However, since the RGB image and the depth image are of different resolutions, there are a lot of holes in the resulting image. So I am trying to move the other way, i.e. mapping the color onto the depth instead of depth to color. So the first problem I am having is that the RGB image has 3

I have a question about save kinect color video as stream How to save Kinect's color video as stream to hard by Kinect SDK 2 in WPF??? i read this link: Save Kinect's color camera video stream in to .avi video For a project, I had to do this. What I've done may not fulfill all your requirements but it may give you an idea. At first I saved every color frame image in local drive with a sequencial naming. Then with ffmpeg I converted those sequential image to video file, in my case it was mp4 video, not avi. To save color image frame sequentially, you may code like below, using System; using

How to display the angles of Kinect skeleton joints? This is the programm you are looking for: namespace Microsoft.Samples.Kinect.SkeletonBasics { using System.IO; using System.IO.Ports; using System.Threading; using System; using System.Windows; using System.Windows.Media; using Microsoft.Kinect; using Microsoft.Kinect.Toolkit.Fusion; using System.Windows.Media.Media3D; public class Angles { public double AngleBetweenTwoVectors(Vector3D vectorA, Vector3D vectorB) { double dotProduct; vectorA.Normalize(); vectorB.Normalize(); dotProduct = Vector3D.DotProduct(vectorA, vectorB); return (double

I was looking over the documentation trying to find anything that will allow me the Kinect/device? I'm trying to get accelerometer data, but not sure how. So far there were two things I've spotted in the guide and docs: XnModuleDeviceInterface/xn::ModuleDevice and XnModuleLockAwareInterface/xn::ModuleLockAwareInterface . I'm wondering if I can use the ModuleDevice Get/Set methods to talk to the device and ask for accelerometer data. If so, how can I get started? Also, I was thinking, if it would be possible to 'lock' openni functionality temporarily while I try to get accelerometer data via

I have a Kinect application that I can generate 1-4 distinct screen points (Left/Right hands for up to 2 people) and I would like to be able to send each Point to the application with focus as a multi touch message. I'm currently using SendInput to send mouse move, mouse down, and mouse up messages, but AFAIK, it doesn't support the WM_TOUCH messages. Does anyone know of an easy way to send multi touch messages in C#? As a test I would like to be able to use the Kinect in MS Paint, and paint with both hands (as well as all the colors of the wind) Ani What you want is to send messages to the
