Running issue with `detectCheckerboardPoints()`

[jino]

Hi, thanks for sharing this work.

I'm trying to run the code in my environment.

• Windows 10
• OpenCV 3.3 (built with VS 2015)
• mexopencv 3.3
• MATLAB R2020b

I could load the included data, however I get a error after click Calibrate button, which says

Function 'detectCheckerboardPoints' is not defined with uint8 parameter type.

in Calibration.getCameraCorners.m.

I checked that readAllImgs returns height * width * 3(channel) * n(number of imgs) data,

disp(size(imCheckerboardSmall))

which is input of detectCheckerboardPoints specified in MATLAB docs.

I have no idea why it does not works... could you give me some advice? Thanks.
