将x，y，z坐标打印到WPF中的数据网格？ [英] Printing out x, y, z coordinates to a datagrid in WPF?

问题描述

 

我想知道如何将关节x，y，z坐标打印到WPF应用程序中的数据网格。或者数据网格甚至是我"收集"的最佳方式。数据？我有一个班级"坐标"和一个mainwindow.xaml已经将datagrid添加到
主窗口。当我的mainwindow.xaml.cs已经有videostream和skeletonstrem时，将它作为一个单独的类是否很好，或者我应该将它实现到主窗口？这是我的mainwindow.xaml.cs和coordinates.cs：

您的问题更适合WPF或XAML数据绑定论坛。就Kinect SDK而言，如果您从各种Skeleton类中获取数据，那么您正在寻找的功能将特定于您选择的编程
语言/环境。你看过BindingList类了吗？

BindingList< T>班级$
http://msdn.microsoft.com/en-us/library /ms132679.aspx

您可以将数据转储到调试控制台，文本框，文件，数据库等任何位置。我认为更关键的问题是您为什么要这样做或者数据需要什么？如果你想"保存"要分析的数据，更适用的位置
可能是文件或数据库。这些是其他论坛的主题，但您需要考虑的事项。

Hi, 

I´m wondering how i could print out a joints x, y, z coordinates to a datagrid in a WPF application. Or is a datagrid even the best way for me to "collect" the data? i have a class "coordinates" and a mainwindow.xaml and already added the datagrid to the mainwindow. Is it good to have it as a separate class when my mainwindow.xaml.cs already has videostream and skeletonstrem, or should i implement it into the mainwindow? Here´s my mainwindow.xaml.cs and coordinates.cs: 

Coordinates.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Kinect;


namespace FysioKinect1
{
    class Coordinates
    {


        private Skeleton[] skeletons = null;
        public float LeftKnee { get; set; }
        public float RightKnee { get; set; }


private void SensorSkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e)
        {
            // Access the skeleton frame
            using (SkeletonFrame skeletonFrame = e.OpenSkeletonFrame())
            {
                if (skeletonFrame != null)
                {
                    if (this.skeletons == null)
                    {
                        // Allocate array of skeletons
                        this.skeletons = new Skeleton[skeletonFrame.SkeletonArrayLength];
                    }


                    // Copy skeletons from this frame
                    skeletonFrame.CopySkeletonDataTo(this.skeletons);


                    // Find first tracked skeleton, if any
                    Skeleton skeleton = this.skeletons.Where(s => s.TrackingState == SkeletonTrackingState.Tracked).FirstOrDefault();


                    if (skeleton != null)
                    {
                        // Obtain the left knee joint; if tracked, print its position
                        Joint j = skeleton.Joints[JointType.KneeLeft];
                        Joint k = skeleton.Joints[JointType.KneeRight];


                        if (j.TrackingState == JointTrackingState.Tracked)
                        {
                            // ofcourse i cant print it out to console, but this is a working console app.
                            //Console.WriteLine("Left knee: " + j.Position.X + ", " + j.Position.Y + ", " + j.Position.Z);
                        }
                        if (k.TrackingState == JointTrackingState.Tracked)
                        {

Your question would be better suited for a WPF or XAML data binding forum. As far as the Kinect SDK goes, if you are getting the data from the various Skeleton classes, then the functionality you are looking for is going to be specific to your programming language/environment of choice. Have you looked at the BindingList class?

BindingList<T> Class
http://msdn.microsoft.com/en-us/library/ms132679.aspx

You can dump the data anywhere debug console, textbox, file, database, etc. I think a more crucial question is what is why you are doing this or what is the need for the data? If you are trying to "save" the data for analysis, a more applicable location might be a file or database. These are topics for other forums but something to consider for what you are trying to do.
