I am the following site
https://jp.mathworks.com/help/vision/ug/stereo-visual-simultaneous-localization-mapping.html
I would like to run SLAM on my stereo camera as a reference.
I have been using the version of MATLAB 2021a for some time, but I installed MATLAB 2021b because the addImageFeatures function in the "Initialize location-aware database" section was introduced from MATLAB 2021b.
However, when I open a calibration session from the Stereo Camera App Calibrator app on MATLAB 2021b, I get the following error:
Error: vision.getMessage (line 6)
The message key'CheckerboardOrigin' cannot be found in the catalog'vision: caltool'.
WARNING: An error occurred while executing the listener callback.
Because of this error, it is not possible to get the value of the stereo camera parameter "stereoParams". I did not get such an error when using MATLAB 2021a.
Can anyone please tell me how to resolve this error?

The spacing of the second line of the error message is strange in several places. Is that an exact copy of the message?

I get no such error. I suggest you call tech support for free installation help since it seems like it's not installed properly.

After reinstalling, the above error could be resolved. However, when I use the "addImageFeatures" function, I get the following error:
The function or variable'addImageFAfter reinstalling, the above error could be resolved. However, when I use the "addImageFeatures" function, I get the following error:atures' is not recognized.
Error: stereoslam (line 94)
addImageFeatures (loopDatabase, currFeaturesLeft, currKeyFrameId);
Isn't the path to recognize the "addImageFeatures" function connected? Also, please let me know if there is a toolbox required to use the "addImageFeatures" function.
