Kinect for Xbox One使用飞行时间深度相机：它是如何工作的？ [英] Kinect for Xbox One uses a time-of-flight depth camera: how does it work?

问题描述

我看过这个关于Kinect for Xbox360的视频，其中使用红外相机可视化Kinect用来计算深度图的红外模式：

使用Kinect for Xbox One我注意到包含红外摄像头，但是当你使用它时你看不到任何类型的模式（在我看来没有使用"点"）。如果我理解正确的话，新技术会评估某种
光线的飞行时间到达场景点并返回传感器（正如所解释的那样
here 。

然而，在
维基百科页面，我读到"与原始Kinect一样，[Kinect for Xbox One传感器使用红外线来读取其环境"。怎么可能，如果我能同时看到IR数据和深度数据？

所以我的问题是：

1. 哪种光线用于计算场景的深度图？它们是IR还是不是？
2. 在故事的最后，哪种技术用于Kinect for Xbox One？
3. 是否有一些详细的参考文档，其中背后的技术解释了Xbox One的Kinect？

解决方案

Kinect v2使用飞行时间技术。您可以在此处阅读更多关于航班的信息： http://blogs.technet.com/b/microsoft_blog/archive/2013/10/02/collaboration-expertise-produce-enhanced-sensing-in-xbox-one.aspx

I have seen this video about Kinect for Xbox360, in which a IR camera is used to visualize the IR pattern used by Kinect to compute the depth map:

With Kinect for Xbox One I noticed that an IR camera is included, but when you use it you cannot see any kind of pattern (seems to me that no "dots" are used). If I understood correctly, the new technology evaluates the time of flight of some kind of rays to reach a point of the scene and come back to the sensor (as explained here).

However, on the Wikipedia page, I read that "as with the original Kinect, the [Kinect for Xbox One] sensor uses infrared to read its environment". How can it be possible, if I can see IR data AND depth ones simultaneously?

So my questions are:

1. which kind of rays are the ones used to compute the depth map of the scene? Are they IR or not?
2. at the end of the story, which kind of technology is used in Kinect for Xbox One?
3. are there some detailed reference documents in which the technology behind Kinect for Xbox One is explained?

Kinect v2 uses time of flight technology. You can read more on time of flight here:http://blogs.technet.com/b/microsoft_blog/archive/2013/10/02/collaboration-expertise-produce-enhanced-sensing-in-xbox-one.aspx
