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
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.
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.
RoadNex (NEXYAD): the rollable lane detection. For a clear urban lane.
RoadNex (NEXYAD): the rollable lane detection. For a urban labe cluttered by a vulnerable road user
One can see on this picture 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 RoadNex 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 :
RoadNex (NEXYAD): the rollable lane detection. Case of clear highway lane
RoadNex (NEXYAD): rollable lane detection while taking over a truck on highway
NEXYAD is currently working on a low-level fusion of ObstaNex and RoadNex in the context presented above.
