houghline transform, it it uses canny edge detection and hough transform. It then places a red line over any detected straight lines.

直线检测及道路边缘检测，包括在DM6437上的实现-use the Hough Transform, Find Local Maxima, and Hough Lines blocks to find the longest line in an image. In the second step, the algorithm used for line detection will be the basis of a lane detection procedure.
