LMD IP core is designed to detect the lane markings on the roadway video scenarios captured from a rear view wide angle camera. It is the foundation of a rear-looking Lane Departure Warning (LDW) systems. With respect to a forward-looking camera system, it aims to a shorter range modelling so a simpler lane model model can be adopted.

LMD structure

The core works in the top view space - orthographic projection. Its functions include:

• image processing filters (Gaussian smoothing and edge detection),
• lane marking detection blocks, and
• Hough Transform model fitting to detect the straight lines corresponding to the lane markings on the road.

The output of the core is the set of straight lines corresponding to lane markings.



Lane Departure Warning

The core is provided with drivers and an embedded software layer implementing the post-processing functions necessary to:

• track the lane,
• establish the vehicle position, and
• generate a warning in case of departing from the current lane.
