我是OpenNI的新手.当我使用Visual Studio 2010 c ++尝试OpenNI示例时,我遇到了以下错误:

我正在使用以下代码如何在C#中模拟鼠标单击？我发现它不起作用.这是代码:

    [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]

    public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);

    private const int MOUSEEVENTF_LEFTDOWN = 0x02;
    private const int MOUSEEVENTF_LEFTUP = 0x04;
    private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
    private const int MOUSEEVENTF_RIGHTUP = 0x10;

    public void DoMouseClick()
    {
        mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 882, 554, 0, 0);
    }

    private void button1_Click(object sender, EventArgs e)
    {
        DoMouseClick();
    }

我也曾尝试更换mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENT_LEFTUP...用mouse_event(MOUSEEVENTF_LEFTDOWN & MOUSEEVENT_LEFTUP...,但仍然没有运气.其他人已经成功了...为什么我不呢？

我有一个应用程序,我创建自己的深度框架(使用Kinect SDK).问题是当检测到人的深度的FPS(然后颜色也是如此)显着减慢时.这是一部关于帧速度减慢的电影.我正在使用的代码:

        using (DepthImageFrame DepthFrame = e.OpenDepthImageFrame())
        {
            depthFrame = DepthFrame;
            pixels1 = GenerateColoredBytes(DepthFrame);

            depthImage = BitmapSource.Create(
                depthFrame.Width, depthFrame.Height, 96, 96, PixelFormats.Bgr32, null, pixels1,
                depthFrame.Width * 4);

            depth.Source = depthImage;
        }

...

    private byte[] GenerateColoredBytes(DepthImageFrame depthFrame2)
    {
        short[] rawDepthData = new short[depthFrame2.PixelDataLength];
        depthFrame.CopyPixelDataTo(rawDepthData);

        byte[] pixels = new byte[depthFrame2.Height * depthFrame2.Width * 4];

        const int BlueIndex = 0;
        const int GreenIndex = 1;
        const int RedIndex = 2;


        for (int depthIndex = 0, colorIndex = 0;
            depthIndex < rawDepthData.Length …

我正在研究一个项目,我需要给一个小型人形机器人(Nao机器人)深度感知.我计划将Kinect连接到机器人的前额,并将其与机器人当前的操作和引导系统(默认系统OPEN NAO)集成,该系统在Linux上运行并通过wifi中继到机器人.

现在我正在摸索使用哪个软件.我看过Point Cloud Library,我看到它用于处理实际数据,OpenNI被定义为一个API框架,可以帮助应用程序访问自然交互设备,如Kinect,然后是官方的Kinect SDK.我只是不确定它们是如何组合在一起的.

我需要将哪些库/框架集成到机器人的操作系统中？

通常，当在我的代码中包含名称空间或程序集时，我经常会遇到奇怪的情况，即名称空间是从另一个名称空间继承而来的，而父名称空间的类却不可用。例如，当使用List<>或时Dictionary<>，我使用System.Collections.Generic名称空间。但是，如果我也想使用IEnumerator，则还必须包括System.Collections名称空间。不应该System.Collections已经被任何成员引用System.Collections.Generic，因为它是一个孩子？两个名称空间还共享同一程序集mscorlib.dll。

为什么当子级不包含父级名称空间？

我尝试将应用程序添加到Django并命名为app main.我键入了django-admin.py startapp main.

当我运行python manage.py runserver时,我遇到这个错误:

在PHP中,您可以编写以下内容:

date_default_timezone_set("UTC");

我该如何用C#编写？

另外,我该怎么写:

declare(ticks=1); 

在C#？
