I am trying to use an open-source code that was developed in 2013. (https://github.com/prclibo/calibration-toolbox/blob/master/scripts/CameraCalibrationBase.m)

Unfortunately, it uses vision.GeometricTransformEstimator, which I understand is no longer included in MATLAB. (https://www.mathworks.com/matlabcentral/answers/521519-what-function-replaced-vision-geometrictransformestimator)

For the specific case here, what is a good way to replace the following lines of code? (Line 151 of the code shared on Github)

estimator = vision.GeometricTransformEstimator; 
estimator.Transform = 'projective';
estimator.AlgebraicDistanceThreshold = obj.maxInlierError;
[~, inliersMaskH] = estimator.step(patternPoints, photoPoints); 

It seems that the purpose of the GeometricTransformEstimator is to obtain inliersMaskH according to some projective transform. What is the recommended way to do this nowadays?

Thank you for the feedback!!
