ROBUSTNESS OF NEXYAD SOFTWARE MODULE FOR ROAD DETECTION : RoadNex

By NEXYAD

Detection of the road, detection of the lane, in front of the vehicle is now a « must-have »
for Advanced Driver Assistance Systems (ADAS) and of course for Autonomous Cars too.
Every R&D team is able to show cases of good detection. The difference between different
modules is robustness : ability to work in many cases (almost every cases).

For instance, robustness consideration led many big Automotive firms to interger the MOBILEYE
detection system : jus because MOBILEYE is more robust than detection systems developed by
those big firms. And robustness is not a matter of deployment : you won’t get a more robust
module is you put 10 000 developers on the project. You need time, big amount of data, and
« smart ideas ».

Note : This robustness definition leads to question on ADAS validation (« almost » every case is
not that well defined … how could we put some maths on those words). NEXYAD has been
developing an applied maths-based methodology for ADAS validation and is currently
recording a validation data base that will be soon available for free worldwide on the internet.

But let’s go back to road detection modules comparison.

There is another difference between road detection systems : do they need white markings
or are they able to work even without markings ?

NEXYAD founders has been working on road detection since the beginning of the 90’s and never
stopped (*). The NEXYAD team is one of the moste experienced team in the world about road detection.
That actually makes the difference, and RoadNex is a module that would take long to develop by
other teams. RoadNex is currently available on PC (windows, Linux) in the real time framework
RT-MAPS. RoadNex will be soon available :
. on electronic device of an Automotive Tier One Company
. on smartphones (so it works in real time on a smartphone usual processor ! try to compare to other modules)

“Texture-based Image Segmentation for Road Recognition with Neural Networks”, G. Yahiaoui, M. de Saint Blancard,

In order to have an idea of what robustness means, here are some case used to test RoadNex :

How many kilometers should you drive to sample those few road scenes variations ?

Nexyad RoadNex v2.2 – Road Detection on little road in Forest

Nexyad RoadNex v2.2 – Road Detection on little road in Forest
RoadNex detecting the lane on the road with or without markings.
The green Arrow shows the possible direction to follow.

Nexyad provides modules for ADAS (Advanced Driver Assistance Systems) : some of those modules such as RoadNex road detection or ObstaNex obstacles detection are competitors of the famous modules of the company Mobileye.

RoadNex v2.2 Desert Track

RoadNex v2.2 Desert track
RoadNex detecting the lane on the desert track : sand road, no markings, stones, etc…
Contrast of colors is very poor, detection is still fine.

Another demo film of RoadNex V2.0 (by NEXYAD) module (road detection in front of a vehicle in urban traffic).

Another demo film of RoadNex V2.0 (by NEXYAD) module (road detection in front of a vehicle in urban traffic).

This module runs as a component of the framework RT-MAPS (by INTEMPORA), and can recognize the road with or without white lines : even European countryside roads are detected.

RoadNex may be used for developing ADAS (Advanced Driver Assistance Systems) and Autonomous Vehicles.

In this demo, RoadNex detects the road shape, illustrated by green lines layer, and the road surface illustrated by the red paint layer.

Notice the scooter that takes over, pushing the green lines and the red paint… It is rare to see demos where objects come over road markings.

You can see on this demo that RoadNex may be an efficient preprocessing system for obstacles detection.
