divide sides of a polygon

Hi, see if anyone can solve a problem I have.

Starting from the binarize.jpeg image and using the drawpoint function I can get the points I show in blue

And then using the polyshape function I can get the polygon whose sides I show painted in blue.

Now, how can I do that, saying that the number of points is, for example, 39, returns me the coordinates of the points I mark in red, equidistant from each other.

Thank you for all
