I need to measure the middle width of trapezoid using opencv c++ as below.

I have an good suggestion from stackoverflow (https://stackoverflow.com/questions/5...) but it is only for Python. I've learnt that it is not easy to convert the followings python codes to c++ especially the following bits.

#Calclate the higest and lowest point
top = tuple(cnt[cnt[:, :, 1].argmin()][0])
bottom = tuple(cnt[cnt[:, :, 1].argmax()][0])

Therefore I am looking for another way to measure the width. Is there any good suggestion?

The thing is I DO understand the math. But I have no idea how to convert any of it to programming.
