Hello, help with the program. We need an .exe program that will automatically measure a part under a microscope using opencv (i.e.) arithmetic operations with pixels, then display info on the screen  
Measurement parameters:

Length, if (long) \<3.9mm or \>4.1mm print “Marriage is long”

Cone height, if (cone) \<0.50mm or \>0.55mm print “Cone defect”

Cone angle, if (angle) \<50⁰ or \> 55⁰ print “Corner Defect”

P.s there is an approximate python code in the construction of contour seams and measurements, but I can’t figure it out
