Kinect for Windows V2中的彩色摄像机的视野（FOV）是多少？

Question

Can't find it anywhere. The kinectforwindows site has the FOV for depth camera. I can't find it in the box either.

Answer 1

@user1809923 is correct. I contacted the developer of the link:

http://smeenk.com/kinect-field-of-view-comparison/

And he responded with this information:

If I remember correctly these FOV values are part of the framedescriptions that you can retrieve with help of the Kinect SDK. Since other people asked for the same info I will update the my blog.

I confirmed his findings by calling the frame's framedescription in the Kinect SDK code and printing the values to the screen.

Answer 2

According to this post

http://smeenk.com/kinect-field-of-view-comparison/

the FOV of the color camera is 84.1 x 53.8. I am not sure, where the author found this information though.

Answer 3

I just wanted to add some more information to this, because the official Kinect Fusion documentation is really bad and because the answer here is correct but the numbers are rounded:

1. assuming, you already have a initialized IColorFrameSource* (eg with the name pColorFrameSource ) you should retrieve the information after you opened the reader: pColorFrameSource->OpenReader(&m_pColorFrameReader); with m_pColorFrameReader beeing IColorFrameReader*

2. the code to retrieve the FOV then looks like this:

    IFrameDescription *f=nullptr; float fovDiago = 0; float fovHori = 0; float fovVerti = 0; HRESULT hh=pColorFrameSource ->CreateFrameDescription(ColorImageFormat::ColorImageFormat_Rgba,&f); if (hh == S_OK) { f->get_DiagonalFieldOfView(&fovDiago); f->get_HorizontalFieldOfView(&fovHoront); f->get_VerticalFieldOfView(&fovVerti); } 

The FOV values not rounded are:

fovDiago =91.9000015
fovHori  =84.0999985
fovVerti =53.7999992
