A lane detection system used behind the lane departure warning system uses the principle of Hough transform and Canny edge detector to detect lane lines from realtime camera images fed from the front-end camera of the automobile. A basic flowchart of how a lane detection algorithm works to help lane departure warning is shown in the figures.
Gradually, existing systems were stabilized, followed by the introduction of disc brakes and anti-lock braking systems. High-tech safety systems were first introduced in 1995 with Electronic Stability Control (ESC). Lane departure warning systems were introduced in the year 1999, and radar assisted adaptive cruise control was introduced in 2005.
