NettetIdeas: 1) Read the picture, binarize, and simply corrode. Then the straight line is more obvious in the original picture, so consider directly using the Hough transform to find the straight line. 2) The Hough line detection may detect multiple overlapping lines. Use the opposite slopes of the upper and lower parts to filter and select two lines.
