Issue Description

<Describe your issue / question / feature request / etc..>

I am wondering it is possible to get undistorted fisheye images in Matlab using given parameters because the model in Matlab seems like different model( Scaramuzza's Taylor model).

T265 uses a distortion model called Kannala-Brandt. OpenCV is usually used to undistort the T265 fisheye (in the link below and in the example program for getting depth from fisheye). I do not know of a means to do it with Matlab unfortunately.

Hi @hojunson

Were you able to utilize the information from MartyG-RealSense to help with your question? Is there anything further needed here? As MartyG-RealSense outlined our only example is what is provided at this time.
