The detection of obstacles on the road, or even recognition of those obstacles, has become an
important issue for the next few years, in order to propose to the driver:

. Smart Systems for driving assistance : ADAS

. Delegation (partial at first, later full) of the driving task, to go step by step to the so-called autonomous vehicle

NEXYAD developed a vision-based obstacle detection system (ObstaNex) that aims to offer an alternative to the current reference product on the market (MobilEye).

We detail the general principles of detection in a previous article (http://nexyad.net/Automotive-Transportation/?p=990).

It is interesting to note that NEXYAD also developed a road detection module named RoadNex.

RoadNex indicates the edges of the rollable way (thus highlights tighter if an obstacle is wayside, this may be useful) and also indicates the rollable flat area (surface) in front of the vehicle.

in motion

One can see on this video that RoadNex, even if it does not detect obstacles (because it detects

lanes), finally finds the "negative" of obstacles.

One of the uses of RoadNex is eliminating rollable areas from possibly detected obstacles by another module (camera, radar, lidar ...): the above image.
A simple confirmation that not colored area corresponds to obstacles detection alarms

is sufficient to confirm the presence of an obstacle and to initiate, for example, the braking.

This system of cooperation between RoadNex and an obstacle detection system (ObstaNex, other

Vision-based module, radar, lidar, ...) is particularly useful in city (see pictures RoadNex above)

and on the highway :

NEXYAD is currently working on a low-level fusion of ObstaNex and RoadNex in the context presented above.
