Problem in MATLAB: Undefined variable

[dtolis99]

Hello, I would like to ask about an error that has occurred. I have downloaded the code and I tried to run the demo calibration pattern. However after the images are loaded and the "### Process Images" Procedure has started it is displayed:

### Process Images
Camera #1: Adding photo #129...
....Matches: 83
Undefined variable "vision" or class
"vision.GeometricTransformEstimator".

Error in CameraCalibrationBase/addPhoto
(line 151)
            estimator =
            vision.GeometricTransformEstimator;

Error in CameraSystemCalibration/addPhoto
(line 102)
            photoIndex =
            obj.cameraCalibrations(cameraIndex).addPhoto(photo);

Error in main (line 107)
    obj.addPhoto(photos(i).camera,
    photos(i).image,
    num2str(photos(i).timeStamp));:

So, why this error is happening? I run MATLAB 2018b on Windows Thank you in advance.

Hi, did you manage to solve it?

Hi, sorry for the delayed answer. Unfortunately I couldn't solve it.

The vision.GeometricTransformEstimator; api seems to have changed a lot since Matlab 2012. See this link for a replacement. https://www.mathworks.com/matlabcentral/answers/521519-what-function-replaced-vision-geometrictransformestimator
