Is it possible to find the bending point using opencv Python?
Sep 27, 2022 · Get the curve points and find the slope along every point. Then find the change in slope from point to point. Find that point that has the maximum change in slope. More specifically see en.wikipedia.org/wiki/Curvature.
python - Measuring true angle of a bended wire with OpenCV - Stack Overflow
Jan 14, 2020 · Extract the bent and unbent wire by extracting the region (blobs) of different strength. Stronger edge will correspond to the unbent wire. Weaker edge will correspond to the bent wire. By using opencv blob analysis function minRectArea, we can obtain the angle, size and center position of the blobs. The angle value w.r.t. horizontal line.
Irregular shape detection and measurement in python opencv
At this point it seems like I have a choice to make. I could either binarise the image, and measure blobs above a threshold (i.e. max value pixels if the blobs are white), or continue with the edge detection by closing and filling contours more fully.

Detect angle and rotate an image in Python - Stack Overflow
Oct 13, 2017 · How can I do this in Python? You could use OpenCV with HoughLines to detect lines in the image. The angle of each of the lines can be found from this: cv2.line(img_before, (x1, y1), (x2, y2), (255, 0, 0), 3) angle = math.degrees(math.atan2(y2 - y1, x2 - x1)) angles.append(angle) This would give you an output as:
