In this image I aim to estimate the outer and inner diameter of screw.
Regarding outer diameter estimation, I was thinking of coming up with some method to hop from one peak of teeth to next peak… storing the pixel positions of peaks. Then regressing a line on those points. Then fitting a circle with max diameter between the regressed lines to estimate the outer diameter of pixel…
I could not get it to the shape of an algorithm to achieve the task. Please help me out in using OpenCV to complete the task.
Thanks in advance!!
