Inquiry about cvexRectifyImages for Stereo Vision

I am doing uncalibrated stereo image rectification following the instructions in this link https://www.mathworks.com/help/vision/ug/uncalibrated-stereo-image-rectification.html

and there seems to be a function which automatically does this rectification with reasonable parameters, as I understand it: cvexRectifyImages or cvexRectifyStereoImages. I tried to do use this in my code and I have the Computer Vision Toolbox installed but the function doesn't seem to be in this toolbox so I can't use it.

Does anyone know where it is located/what toolbox I need to download to use it?

Hi Andrew,

I understand you want to utilise the "cvexRectifyImages" function for the uncalibrated stereo image rectification workflow. This function is indeed a part of computer vision toolbox and can be found in the following example documentation: https://www.mathworks.com/help/vision/ug/uncalibrated-stereo-image-rectification.html.

Please use the following command to download and open the above example in your local MATLAB after which the "cvexRectifyImages.m" file will be visible in MATLAB's current folder directory panel.

openExample('vision/UncalibratedStereoRectificationExample')

I have also attached "cvexRectifyImages.m" file with this answer for your reference.

You can also check out related function named "rectifyStereoImages" which rectifies input images based on stereo parameters.For more information, please refer to following link:

Hope this helps.
