The Hough Transform is a popular technique to detect any shape if you can represent that shape in a mathematical form, It can detect the shape even if it is. This reduces the number of undesired results to filter out as you now have only exactly horizontal and exactly vertical lines in the result. Everything explained above is encapsulated in the OpenCV function, cv2. Jan 8, 2013 A line can be represented as or in a parametric form, as where is the perpendicular distance from the origin to the line, and is the angle formed by this perpendicular line and the horizontal axis measured in counter-clockwise (That direction varies on how you represent the coordinate system. . png'). 5. Also, we use a different image that will actually help us visualize the results of the algorithm. Any line can be represented in term of r and .
