How can I access the infrared data stream of Kinect V2?

I'm currently using Kinect V2 on Image Acquisition Toolbox Version 5.0. The infrared data stream (amplitude image) does not show up in the Hardware Browser as it used to be in Kinect V1. Any ideas about accessing the infrared stream in this toolbox or other Matlab functions?

Thanks for help in advance,

Hi RangeRes,

The infrared stream is not supported with the Kinect V2, but we do expose the depth stream and all the skeletal tracking information. More information here.

Will that not work? We haven't had any users ask for the infrared stream yet, but we would consider adding that in a future release of the Image Acquisition Toolbox.

Thanks Madhura for the response.

However, I still need the infrared data along with the depth data. Important reasons are that the infrared data is simultaneously acquired from the same angle-of-view of the depth data (compared with the RGB image), has the same resolution and quantifies physical characteristics of the reflected infrared rays over the surface (i.e., reflected rays' amplitude). I would be grateful if you teach me a method to acquire it via Matlab (even without using the Image Acquisition Toolbox).

Thanks in advance!

Hi RangeRes,

Option1: Write a MEX file (by that, you can write a C++ file that communicates with the Kinect directly.)

Option2 (better): Write your own custom adaptor for using the Custom Adaptor Kit. Link to the adaptor kit is here.

Hello Madhura, I would be extremely interested in being able to retrieve the infrared stream as well. At the moment I'm using a third party toolbox (Mex files), but I have issues with frame dropping that should be solved by the way the IMAQ toolbox triggers data.

Hello Jonathan, I have the same problem as you, could you send me those Mex files to acquire IR stream along with depth stream? I would be very grateful. Thank you in advance! Luis
