2015-02-24 21:30:54 -0600 | asked a question | Draw lines from centroid of contour at given angle till edge of contour I have a contour named 'cnt' obtained from the image below: for which I am able to find the centroid like this: I now want to draw N number of lines, each 360/N degrees apart, starting from the centroid and passing through all possible points of intersection with the contour. The cv2.line() function requires start point and end point but I don't have the end point. If I had drawn a line passing through centroid with a slope of Tan(360/N) I would have found the intersection of the line with the contour using bitwise_and but I'm not able to figure out a way to draw that line. Any help would be much appreciated. |
