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)

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

SafetyNex World Premiere Road Safety App

SafetyNex & EcoGyzer : the Driver Behaviour Signature

SafetyNex is a Nexyad Module for ADAS that estimates the risk (or safety) in driving 100% correlated with accidentology. It is unique and disruptive in the whole world of Road Safety.
Recently, EcoGyzer a tool by the french company Nomadic Solutions, has been integrated to SafetyNex to estimate the Eco driving.
Now we are proud to announce that SafetyNex & EcoGyzer as a world premiere App estimating the Driver Behaviour Signature. To figure the Driver Behavour Signature, we imagined a special mapping as you’ll see on the demo films.
Every second in driving, one point is plotted on the mapping. The more right a point is, the more Eco is the driving; the more up, the more safe it is. At the end of the path, there is a cloud of points called the Driver Behaviour Signature.
In the following demo films, we show four different driving behaviour signatures for the same path :


The Good Driver



The Bad Driver



The Quiet-Dangerous Driver



The Sportive-Safe Driver


Comparison of the four Driver Behaviour Signatures

Nexyad ADAS Validation Database still in Progress

NEXYAD has been starting the development of a data base for artificial vision-based ADAS test and validation.

This data base will be relevant and unique because it is fully decribed in two ways :
. reality : position of road and obstacles
. driving situation (i.e. curve in a foggy weather with pedestrian crossing, …) using the methology AGENDA.

– « Validation of Advanced Driving Assistance Systems », G. Yahiaoui, N. du Lac, SafetyWeek congress, Aschaffenburg, May 2015.

Business details :
A part of this data base will be soon available for free on the internet, to the worldwide ADAS and Autonomous
vehicle community (labos and firms).

(Free access to the NEXYAD Artificial Vision-based ADAS Validation Database)
The complete data base should be available soon through an annual membership.

RoadNex v2.2 Robustness

On a new release v2.2 of RoadNex, we’ve added an arrow that shows the direction to be followed by the vehicle according to our road detection always defined by the edges of the rollable track and the surface of the rollable track. New tests were performed on videos of different types of roads, including tracks in the desert or lit roads by car lights at night.
These examples demonstrate the robustness of our module software that is more and more a reel competitor of lanes Detection System developed by Mobileye.
