如何使用Microsoft Kinect for Windows SDK版本1.7 C#检测打开/关闭的手 [英] How to detect open/closed hand using Microsoft Kinect for Windows SDK ver 1.7 C#

问题描述

我最近开始使用Microsoft Kinect for Windows SDK来使用Kinect设备对某些内容进行编程.

I have recently started using Microsoft Kinect for Windows SDK to program some stuff using the Kinect the device.

我正在捣蛋，寻找一种方法来检测某只手是闭合还是张开.

I am busting my ass to find a way to detect whether a certain hand is closed or opened.

我看到了Kinect for Windows Toolkit，但是该文档不存在，我找不到使它工作的方法.

I saw the Kinect for Windows Toolkit but the documentation is none existent and I can't find a way to make it work.

有人知道一种检测手部状况的简单方法吗?如果它不需要使用Kinect工具包，那就更好了.

Does anyone knows of a simple way to detect the hand's situation? even better if it doesn't involve the need to use the Kinect toolkit.

推荐答案

这是我最终做到的方式:

This is how I did it eventually:

首先，我们需要一个看起来像这样的伪类:

First things first, we need a dummy class that looks somewhat like this:

public class DummyInteractionClient : IInteractionClient
{
    public InteractionInfo GetInteractionInfoAtLocation(
        int skeletonTrackingId,
        InteractionHandType handType,
        double x,
        double y)
    {
        var result = new InteractionInfo();
        result.IsGripTarget = true;
        result.IsPressTarget = true;
        result.PressAttractionPointX = 0.5;
        result.PressAttractionPointY = 0.5;
        result.PressTargetControlId = 1;

        return result;
    }
}

然后，在主要应用程序代码中，我们需要宣布有关交互事件处理程序的信息，如下所示:

Then, in the main application code we need to announce about the interactions events handler like this:

this.interactionStream = new InteractionStream(args.NewSensor, new DummyInteractionClient());
                this.interactionStream.InteractionFrameReady += InteractionStreamOnInteractionFrameReady;

最后，是处理程序本身的代码:

Finally, the code to the handler itself:

private void InteractionStreamOnInteractionFrameReady(object sender, InteractionFrameReadyEventArgs e)
    {
        using (InteractionFrame frame = e.OpenInteractionFrame())
        {
            if (frame != null)
            {
                if (this.userInfos == null)
                {
                    this.userInfos = new UserInfo[InteractionFrame.UserInfoArrayLength];
                }

                frame.CopyInteractionDataTo(this.userInfos);
            }
            else
            {
                return;
            }
        }



        foreach (UserInfo userInfo in this.userInfos)
        {
            foreach (InteractionHandPointer handPointer in userInfo.HandPointers)
            {
                string action = null;

                switch (handPointer.HandEventType)
                {
                    case InteractionHandEventType.Grip:
                        action = "gripped";
                        break;

                    case InteractionHandEventType.GripRelease:
                        action = "released";

                        break;
                }

                if (action != null)
                {
                    string handSide = "unknown";

                    switch (handPointer.HandType)
                    {
                        case InteractionHandType.Left:
                            handSide = "left";
                            break;

                        case InteractionHandType.Right:
                            handSide = "right";
                            break;
                    }

                    if (handSide == "left")
                    {
                        if (action == "released")
                        {
                            // left hand released code here
                        }
                        else
                        {
                            // left hand gripped code here
                        }
                    }
                    else
                    {
                        if (action == "released")
                        {
                            // right hand released code here
                        }
                        else
                        {
                            // right hand gripped code here
                        }
                    }
                }
            }
        }
    }
