This program is made public for demonstration and archive purposes. It is very unfinished. It involves a lot of hacks and workarounds. It completely ignores many problems encountered. So don't even try to read it, it is a waste of time.

An unfinished personal project of vision system (computer/machine vision) metrology software I wrote years ago (November 2017). It uses OpenCV to measure the machine part's dimensions. I tested it a little bit on some CAD pictures on Windows operating system. I gave up midway due to laziness and lack of knowledge. I was in the process of rewriting the software at that time, so probably won't work. It probably won't compile nowadays.

If I remember correctly, the process requires reference objects that have known dimensions. I was using a circle and a polygon. First, the program thresholding the picture. Then, it finds the contour. Finally, it measures the dimensions based on the contour data.

For example, if we know the dimensions of the reference object and a straight line on the reference object's contour is 1 cm, if a straight line on the target part's contour is 2 times the length of the straight line on my reference object's contour, I can get the target part's straight line is 1x2=2cm. The same also applies to a circle's radius, diagonal line, arc, etc.

In backup directory, there are some older source codes files. At that time, I was not using git because I was not fluent and was too afraid to use git.
