Parifex speeds towards AI

Paris-based camera specialist is branching out in ITS with 3D-Lidar technology.

French road enforcement specialist Parifex is diversifying into new areas using the 3D-Lidar technology developed for its speed cameras such as the Vigie Mobile brand.

As well as creating a new division dedicated to smart cities, Parifex hired 10 more staff during the Covid-19 lockdown to its R&D team to bolster work in artificial intelligence (AI) and image processing.

“We noticed there were a lot of opportunities,” explains sales manager Nathalie Deguen in a lengthy interview with ITS International.

“We noticed that there could be some other application from speed enforcement: it could be used as a sensor for data collection, installed on existing infrastructure or on a tripod – like Vigie Mobile.”

Parifex found that clients themselves had ideas about what they could use it for: issues with parking, for instance, or to get more granular information on traffic management. The company invested more to try to offer solutions for these varied applications – it routinely puts 15% of its turnover into R&D.

Deguen continues: “Basically the start of our discussion was always to show what the system could do: ‘These are the advantages of the Lidar, this is what we can see, this is the kind of information we can collect, this is how the system could help you – do you need it for any specific reason?’”

Despite this, she insists that the Paris-based firm’s core of enforcement products will remain.

“This is our business, historically; we have some great references, we are well known as experts in this field and I think this will help us to diversify: it’s in its very early days but these activities are closely linked.”

In 2021 Parifex will deploy its new multi-violation urban radar system, Nomad, as part of the roll-out of a new contract.

3D-lidar enforcement technology first for Parifex

In order to maintain the control effort on vehicles and motorised two-wheelers, while significantly increasing offender detection rates, the French road enforcement department trusts in Vigie double-sided interception fixed radar, the first stationary speed enforcement system using 3D-Lidar technology.

As part of a programme to modernise its national radar installation base, the French department wanted to deploy digital speed control devices with simultaneous shots of the front and rear of the infringing vehicle, within a single, roadside device.  

The Vigie double-sided 3D-Lidar unit which PARIFEX developed has a tracking feature and is able to take front and rear photos of vehicles and motorcycles. This means that it can obtain both the face of the driver and the licence plate. Having front and rear shots of an offending vehicle significantly improves offender prosecution rates.

This cutting-edge technology enables it to offer a range of other applications for smart cities and connected and autonomous vehicles. Indeed, the company has developed ITS systems allowing vehicle identification, red light running detection, automatic number-plate recognition (ANPR), intelligent counting, as well as a range of other applications using 3D-Lidar technology and Artificial Intelligence (AI), including machine learning techniques. Moreover, PARIFEX is currently taking part in autonomous vehicle tests by providing a tracking solution, for instance located on a roundabout, that can monitor vehicles, and even pedestrians or other vulnerable road users. Since the system is able to calculate speed and distance for each object it observes, it can autonomously transmit critical safety information to connected vehicles.
