OpenCV: Hough Line Transform

Web8 de jan. de 2013 · Draws a line segment connecting two points. The function line draws the line segment between pt1 and pt2 points in the image. The line is clipped by the image boundaries. For non-antialiased lines with integer coordinates, the 8-connected or 4-connected Bresenham algorithm is used. Thick lines are drawn with rounding endings. … One approach is to use the Hough Transform to detect the lines and obtain the angle of each line. The angle between the two lines can then be found by subtracting the difference between the two lines.
