Future Events

NEXYAD at the Mondial de l’Automobile 2016, october 5th.

NEXYAD will be on Mondial de l’Automobile 2016 at Paris, october 5th invited by BMW on BMW booth.
After have been choosen as one of the three winners of BMW Techdate Challenge 2016.
Mondial Nexyad

Reminder : BMW Techdate wished to push ahead the french innovative high tech and identify new partners for technology matters. After a picky skimming, 20 startups were selected to present their project in front of a professional panel of Automotive, mobility, and connected car experts.
The quality of SafetyNex impressed the jury and the 9th june, BMW France announced Nexyad as part of the 3 winners of the first Techdate Challenge with Oridao and Sentryo.

Accident fatalities in Tesla car : NEXYAD modules might prevent accident.

Accident fatalities in a TESLA car might have been avoided by using software modules of NEXYAD : the time for monitoring circuit has come.
By NEXYAD

Processing circuit, informing auto-pilot systems, control, etc … from perception, data fusion, decision-making, and automatic control of actuators, are usually very well designed, and based on high-performance modules. But unfortunately, this is not enough to void the risk of accidents. Indeed, for the treatment of this risk, it lacks a parallel circuit (parallel and independent) called “monitoring” circuit.
To understand this need for a monitoring circuit, one must first understand the level of complexity of a road scene viewed from a camera.

The variability of road scenes is actually much more than what a normal person comes to imagine. Indeed, a color image, which has eight bits for each colors (then, 24-bit, as there are 3 colors) may encode 224 different color levels per pixel (more than 65,000 different possible values). HD video has more than 2 million pixels.
This means that the matrix of HD 8-bit color image may encode more than 65 0002 000 000 images !
This huge number is simply unimaginable.

White paper “Vehicle Telematics, Measurement of Risk in Driving, Respect of Individual Privacy” (Auto Insurance and ADAS applications)

SafetyNex for Insurance

“Vehicle Telematics, measurement of risk in driving, respect of individual privacy” is the new white paper from Nexyad, which explains important points to check on a vehicle telematics application to assess the risk taken by the driver about his driving task.

The calculation of risk requires having contextualized data that are inherently confidential, personal, and therefore which must in no case be recorded on computer servers in a cloud as they contain, directly or indirectly, information about offenses (in France it is forbidden: by respect of the criminal code and rules CNIL).

A scale model car to test ADAS (ADAS validation)

NEXYAD will use a scale model car for ADAS and driverless software modules testing & validation.

Nexyad built their own intelligent scale model of car integrating a camera and telecommunications to a PC running the RT-MAPS framework (by INTEMPORA).

Scale Model Car Nexyad

The PC runs real world detection software modules of NEXYAD into the framework RT-MAPS. Then the
scale model car can evoluate on a scale model landscape where it is easy to generate complex use cases
such as sun rising and other perturbations that are not easy to record in the real world and that are not that easy to simulate.

Beside, Nexyad built a testing and validation database that will represent thousands of million km of natural driving with the fewest number of vids as possible.
NB : this NEXYAD validation database will be available for free to every research and development team in the world on the NEXYAD web site.

Database

This database will be used by NEXYAD of course to test and validate their own software modules for ADAS and Driverless cars :
. RoadNex for road detection
. ObstaNex for obstacles detection
. ObstaNex BiCam for obstacles detection using 2 cams
. VisiNex for visibility measurement
. SafetyNex for real time onboard risk assessment

This database is the result of a advanced methodology published in the 90’s by Nexyad Founder. The methodology “AGENDA” allows to build and validate camera-based complex detection and recognition systems (for ADAS and driverless cars).
This methodology was recently re-published and presented in different symposiums in Europe to show exactly how it may be used by car manufacturers and their OEMs.



SafetyNex available on
App Store and Google Play Store end of october

SafetyNex One Pager

Interest for the driver :
. SafetyNex warns you when there is a danger ahead in function of your car speed (save your health or your life)
. SafetyNex warns you when your speed is over legal limitation (save your money and your driving licence)

Interest for Insurance Companies :
. SafetyNex provides qualified data as histogram of risk taken by the driver, eco driving score, statistics of usages, contingency tables, etc.

Interests for car manufacturers :
. SafetyNex can be used as ADAS for customers
. SafetyNex gives the risk taken by the robot driver of future Autonomous Car

ROBUSTNESS OF NEXYAD SOFTWARE MODULE
FOR ROAD DETECTION : RoadNex

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)
(*) publication at a scientific congress in France in 1993 :
“Texture-based Image Segmentation for Road Recognition with Neural Networks”, G. Yahiaoui, M. de Saint Blancard,
Sixth international conference on neural networks and their industrial & cognitive applications NeuroNîmes93, EC2,
Nîmes, 1993,

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