The Road Line Detection library is used to draw lane lines in ADAS applications. Each lane line is represented by a number representing the category. A vector<Point> is used to draw the lane line. In the test code, a color map is used. Different types of lane lines are represented by different colors. The point is stored in the container vector, and the polygon interface cv::polylines() of OpenCV is used to draw the lane line. The following image shows the result of road line detection.
