I am interested in obtaining a center line of road. I am working on video frames(bgr). Then applying threshold,erosion and canny edge detection.
Further I am applying sobel derivative and then finally drawing contours.
I am thinking of taking small strips along y axis, obtaining x coordinates and the finding the mean of these x coordinates. But so far I have not come across any function which would allow me to do this.
Also if I get these values how should I store them ?
