Lane departures

In terms of image processing this fruit is about as low hanging as it gets. Detection of lanes on motorways is really a special case, with the markings on other types of road being not nearly so consistent in appearance.



The processing needed to do this is fairly minimal, so it could be implemented on an FPGA or DSP inside the camera housing itself, with a GPS receiver being used to calculate approximate speed so that it doesn't need to be wired into the car's other systems. Alternatively speed could be estimated from optical flow, although that would require more processing power since it involves finding correspondences between frames.

Some other vehicle image processing features can be seen here.



Presently I think that systems like this are only implemented on very high end luxury vehicles, but I expect that before long this will be a standard feature in all vehicles.
