Camera Calibration Kinect Vision Caltech IR camera

So I was trying to calibrate the IR camera of the new Kinect v2 sensor. So I am following all the steps from here http://www.vision.caltech.edu/bouguetj/calib_doc/htmls/example.html

The problem I am having is the following: The IR image looks fine but once I put it through the program the image I am getting is a mostly white(bright) image. See pics below

Anyone encountered this issue before?

Thanks

You are not reading the IR image pixels correctly. The format is 16 bits per pixel, with only the high 10 ones used (see specification here). You are probably visualizing them as if they were 8bpp images, and therefore they end up white-saturated.

The simplest thing you can do is downshift the values by 8 bits (i.e. divide by 256) before interpreting them in a "standard" 8bpp image. However, in Matlab you can simply use imagesc to display them with color scaling.
