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.
The lane detection system used by the lane departure warning system uses image processing techniques to detect lane lines from real-time camera images fed from cameras mounted on the automobile. Examples of image processing techniques used include the Hough transform , Canny edge detector , Gabor filter and deep learning .
Lane centering assists the driver in keeping the vehicle centered in a lane. [41] A lane-centering system may autonomously take over the steering when it determines the driver is at risk of deterring from the lane. [41] This system uses cameras to monitor lane markings to stay within a safe distance between both sides of the lane. [42]
Lane departure warning uses cameras and several sensors to detect lane markers and monitor the distance between the vehicle and these lanes. If the vehicle leaves the lane without signaling, a beep may be heard. It may also use physical systems such as vibration of the steering wheel or seat. In advanced versions, it may also apply brakes or ...
Bus lane cameras that detect vehicles that should not be in the bus lane. These may be mounted on buses themselves as well as by the roadside. [39] Fixed camera systems can be housed in boxes, mounted on poles beside the road, or attached to gantries over the road, or to overpasses or bridges. Cameras can be concealed, for example in garbage ...
Additionally, many motorways, called smart motorways, have now been equipped with the newest signs and signals for variable mandatory speed limits and lane control. The system replaced the Automatic Incident Detection (AID) system which was trialled in 1989 on an 83 kilometres (52 mi) section of the M1 motorway. [1]
