使用4个Kinects [英] Use 4 Kinects

问题描述

我正在连接4个Kinects，描述为API支持。

I am connecting 4 Kinects, described as supported by the API.

我获得了Kinect Explorer Demo（C ++）的以下结果

I am getting the following results for the Kinect Explorer Demo (C++)

我试图用这个数字保存1000个单词，显示4个连接的Kinects，但没有视频/深度图像。

I am trying to save 1000 words with this figure, which shows 4 connected Kinects, but no video/depth image.

我的设备管理器中有以下设备（葡萄牙语）：

I have the following devices in my Device Manager (in portuguese):

我已经感到沮丧，因为在另一台只有2个USB 2.0的计算机上我可以拥有视频与2 Kinects流。在这台拥有更多USB集线器的计算机中，我只能拥有一个视频流，因为第二个视频会冻结，第三个和
排在前面，它们不会显示屏幕截图显示的任何内容，尽管所有内容都已连接（没有带宽问题）。

I am already frustrated because in another computer with only 2 USB 2.0 I could have video stream with 2 Kinects. In this computer that has many more USBs hub I can only have ONE video stream because, with the second the video freezes, with the third and forth and they don´t show anything as the screenshots shows, although all are connected (no bandwidth issues).

我不是在讨论USB兼容性问题，如本论坛中的许多消息所示，只是想连接并在4  Kinects中拥有视频/深度API声明，所以我想对这一特定问题给出实际答案。我的研究依赖于
来实现，所以请告诉我你自己如何插入4个Kinect。

I am not trying to discuss USB compatibility issues, as shown in many messages in this forum,  just want to connect and have video/depth in 4 Kinects as the API states, so I would like a practical answer to this particular issue. My research depends on this to work, so please show me how even you have to plug 4 Kinects yourself.

亲切的问候，

推荐答案

在同一USB主控制器上不能有4个Kinect传感器。一个传感器将占用一个主控制器的约60％的可用带宽。您需要购买PCIx扩展卡并在总线上有足够的吞吐量，以确保机器能够执行此操作
。

You cannot have 4 Kinect sensors on the same USB host controller. One sensor will take ~60% of the available bandwidth for one host controller. You need to purchase PCIx expansion cards and have enough throughput on the bus to ensure the machine is capable of doing this.

根据系统的制造，您可能拥有系统外部有多个USB2端口，但它们共享相同的USB主机控制器。您可以使用设备管理器检查芯片组的带宽使用情况。此外，您可以
按连接对视图进行排序，并查看哪些设备连接到哪个USB主机控制器。

Depending on the manufacturing of the system, you may have multiple USB2 ports on the outside of the system, but they are sharing the same USB Host controller. You can use device manager to check the bandwidth usage of the chipset. Additionally, you can sort the view by connection and see which devices are connected to which usb host controller.
