Kinect Azure Field of View

Question

Kinect Azure Field of View

Andru 1

I am trying to understand what the field of view is for the RGB camera and the depth camera. From what I can tell there is a 120 degree FoV option for the depth camera but I haven't been able to tell if there is a wide angle option for the RGB as well.

We need a wide FoV on both the depth and the RGB cameras for our use case.

Thank you for any help.

Hello @Andru Sorry for the delay in the response.

Wanted to share a few doc links and the reference thread on this topic, please do let us know if you need further help in this matter. We would be happy to help!

WFOV (Wide field-of-view depth mode)

Reference : Azure Kinect DK field of view.

You can use simple trigonometry to calculate the width of the FOV for a specific distance from the camera.
There is also the 75x65 deg FOV of NFOV mode. You can find the full specifications here
https://learn.microsoft.com/en-us/azure/Kinect-dk/hardware-specification
Specifically looking at the 120 def FOV. You can split the FOV into 2x 60 deg (angle between acute and hypotenuse) right angle triangles with the opposite 5ft in length (1/2 of 10ft). The acute is calculated as tan(60) = 5 ft / a -> a = 5 ft / tan(60) = 2.88 ft. So the Azure Kinect camera needs to be at least 2.88 ft from a 10 ft subject to completely visualize the subject.
