Mar 24, 2016 a modified code which detects not one but many Hough lines is shown in an image and obtain its y-coordinates using python and opencv?
endl;. cout << "Usage:" << endl;. cout << "./gpu-example-houghlines <image_name>, Default is ../data/pic1.pngn" << endl;. } int main(int argc, const char* argv[]).
Explanation. Load an image. Mat src = imread(filename, 0); if(src. Detect the edges of the image by using a Canny detector. Canny(src, dst, 50, 200, 3); Standard Hough Line Transform. Probabilistic Hough Line Transform. Display the original image and the detected lines: Wait until the user exits the program.
Everything explained above is encapsulated in the OpenCV function, cv2.HoughLines(). It simply returns an array of values. is measured in pixels and is measured in radians. First parameter, Input image should be a binary image, so apply threshold or use canny edge detection before finding applying hough transform.

Nov 5, 2015 I found the solution. The code example only shows the first hough line. In case you want to print all the hough lines on an image you have to
