Seems mexopencv is not added to MATLAB path.

Execute this in MATLAB command line: addpath('C:\path\to\mexopencv')

Then execute this in MATLAB command line: help cv

after we failed,we choose the .EXE file ,we setup the MATLAB runtime 2021a in the path "matlab/toolbox\compiler\deploy\win64",we try again,but we still failed, so what's wrong? P.S.: we ues the photos in your file that i downloaded, but we cannot figure it out

[BingyaoHuang]

Can you post the error message?

[LuShixong]

Of course, we set up the opencv3.4.1 and mexopencv in the MATLAB file and addpath('G:to\mexopencv\mexopencv-3.4.1\mexopencv-3.4.1') and addpath('G:to\opencv3.4.1\opencv') and addpath('G:to\single-shot-pro-cam-calib-0.1') but that's the result: i don't know what's wrong with it. i tried 2019a and 2021a and .EXE ,but they all failed. when i clicked the calibrate button in the .EXE ,nothing happened. i really want to learn more about

[BingyaoHuang]

Maybe it's due to mexopencv version (you installed 3.4.1). However, in README usage section, I mentioned using mexOpenCV v3.3.0.

Try mexOpenCV v3.3.0 and let me know if this error pops up again.
