低帧速率 [英] LOW FRAME RATE

问题描述

大家好。 

Hello to all. 

我是kinect v2.0的新用户。

I'm a new user of kinect v2.0.

我遇到了低的问题帧速率甚至在低速时传感器损失如下。

I got the problem of low frame rate and even at low velocity the sensor loss the following.

我有一台全新的NVIDIA QUADRO K4200，因为虽然速度不是很快，但它提供了Direct X的最高驱动版本以及带有3D视觉套件的立体声同步功能3D。

I have a new NVIDIA QUADRO K4200, because although is not very quick, it provides the highest driver version of Direct X and also the stereo syncronization with 3D vision kit to edit in 3D.

我的CPU是i7-3820四核@ 3.60 GHz

我的主板是GIGABYTE X79 UD3，提供第三代PCI X16，我认为PCI x1是第二代（直到5Gps）。

My motherboard is a GIGABYTE X79 UD3, which provides PCI X16 of third generation, and I think that PCI x1 is of second generation (until 5Gps).

我还有专用的USB 3.0卡：ORICO USB3.0扩展卡（PVU3-2O2I）

Also I got a dedicated USB 3.0 card: ORICO USB3.0 Expansion Card (PVU3-2O2I)

当我将我的kinect连接到集成USB 3.0的主板时，颜色有效，但我在验证器和3D构建器程序中获得低帧率。

When I connect my kinect to the motherboard integrated USB 3.0, the color works, but I get low frame rate in the verifier and in the 3D builder program.

当我通过专用卡连接它时，其驱动程序已经启动（对于XHCI 控制器），我获得低速率和无颜色（它比上面的情况更差）我在PCI X16插槽中测试了这张卡，但我的系统无法识别它。我的
激活了我的BIOS上的EHCI和XHCI。但它并没有解决我的问题。

When I connect it through the dedicated card, with its drivers instaled (for the XHCI controller), i get low rate and no color (it is worse than in the above case). I tested this card also in a PCI X16 slot, but it is not recognized by my system. I als activated both: EHCI and XHCI on my BIOS. But it does't solve my problem.

你知道我的问题在哪里吗？，quadro GPU是正确的吗？，也许购买在foro中使用的TS-PDU 3 USB 3.0卡是可以的（social.msdn。 microsoft.com/Forums/es-ES/bb379e8b-4258-40d6-92e4-56dd95d7b0bb/confirmed-list-of-usb-30-pcie-cardslaptopsconfigurations-which-work-for-kinect-v2-during?forum=kinectv2sdk）

Do you know where is my problem?, the quadro GPU it is correct?, maybe buying the TS-PDU 3 USB 3.0 card sugested in the foro is OK (social.msdn.microsoft.com/Forums/es-ES/bb379e8b-4258-40d6-92e4-56dd95d7b0bb/confirmed-list-of-usb-30-pcie-cardslaptopsconfigurations-which-work-for-kinect-v2-during?forum=kinectv2sdk)

提前谢谢。

Thank you in advance.

推荐答案

供您参考：

如果没有兼容DirectX 11的图形卡，Kinect for Windows v2 SDK将无法运行。 DirectX 11卡可能会运行，但帧速率会降低。



当前的Windows Update NVidia驱动程序会导致许多问题，这些问题由最新的WHQL NVidia驱动程序修复来自NVidia网站。最容易识别的问题是寻找包含红外线流中全零的返回。如果你的
正在运行NVidia显卡，请确保你安装了NVidia的最新WHQL驱动程序网站。



内置USB 3.0主机控制器（英特尔或瑞萨芯片组）。

如果您要为您的USB 3.0功能添加现有PC通过适配器，请确保它是符合Windows 8标准的设备，并且它支持Gen-2。有关详细信息，请参阅"入门"的故障排除部分。

支持DX11的图形适配器（见下面已知的好适配器列表）

英特尔HD 4400集成显示适配器

ATI Radeon HD 5400系列

ATI Radeon HD 6570

ATI Radeon HD 7800（256位GDDR5 2GB / 1000Mhz）

NVidia Quadro 600

NVidia GeForce GT 640

NVidia GeForce GTX 660

NVidia Quadro K1000M



许多笔记本电脑切换到低功耗模式，在没有外部电源的情况下降低GPU性能。如果您打算在使用电池供电的笔记本电脑上工作，则应禁用GPU的低功耗模式。在某些情况下，即使禁用低功耗模式，GPU性能也会因电池电量而受到限制。在这种情况下，您应该在使用Kinect for Windows传感器时插入笔记本电脑。

颜色数据流在低光照下会减少

在光线不足的情况下，Kinect会在光线不足的情况下回落到15 FPS。

For your reference:
The Kinect for Windows v2 SDK will not function without a DirectX 11 compatible graphics card. Lower end DirectX 11 cards will likely function, but at degraded frame rates.

The current Windows Update NVidia driver causes a number of issues which are fixed by the most recent WHQL NVidia driver from the NVidia website. The easiest to identify an issue is to look for a return that contains all zeros in the Infrared stream. If you are running an NVidia graphics card, ensure that you have the latest WHQL driver installed from NVidia’s website.

Built-in USB 3.0 host controller (Intel or Renesas chipset).
If you're adding USB 3.0 functionality to your existing PC through an adapter, please ensure that it is a Windows 8 compliant device and that it supports Gen-2. See the troubleshooting section of Getting Started for more information.
DX11 capable graphics adapter (see list of known good adapters below)
Intel HD 4400 integrated display adapter

Many laptops switch to a low-power mode that reduces GPU performance when operating without external power. If you plan to work on a laptop that is operating on battery power, you should disable low-power mode for your GPU. In some cases, the GPU performance is limited while on battery power even when low-power mode is disabled. In this case, you should keep your laptop plugged in while using the Kinect for Windows sensor.

The color data stream is diminished in low light
Under low light conditions, Kinect will fall back to 15 FPS under low light conditions.
