A monocular vision based advanced lighting automation system for driving assistance

This paper presents a night time vehicle detection system performing automatic headlamp control in the frame work of driving assistance. In such application dealing with sensor, processing and actuator, we focus on image processing techniques developed in this project. From our embedded camera, image processing enables to detect vehicles ahead and estimates their positions in order to increase driver visibility by adjusting headlamps. We review algorithms (segmentation, classification, tracking and position estimation) in detail and present results comparing driver dazzling between static headlamps and intelligent headlamps. Our system detection range is above 600m for headlamps and about 400m for tail lamps which is sufficient to avoid glaring of other road users. Classification performances are above 97% of true positive rate evaluated on a validation database (frame by frame detection). The final vehicle detection is guaranteed at 100% of recognition by attributing a minimum confidence accumulated over successive fames. By way of conclusion, we introduce perspective of advanced lighting automation.

Innovative lighting systems enhance road safety

In the last twenty years, significant progress has been made in the field of headlight technology. Today’s systems are making driving at night much safer. Future intelligent lighting systems, which make use of computer-aided image processing sensors, will bring further safety benefits. Automotive supplier Valeo is currently developing such lighting systems.

Innovative Lichtsysteme erhöhen die Verkehrssicherheit

Die Scheinwerfertechnik hat sich in den vergangenen zwei Jahrzehnten entscheidend weiterentwickelt. Moderne Systeme machen die nachtliche Fahrt bereits heute deutlich sicherer. Ein weiteres Plus an Sicherheit werden Beleuchtungssysteme liefern, die rechnergestutzt und mit bildverarbeitender Sensorik arbeiten. Der Zulieferer Valeo erarbeitet solche zukunftigen Beleuchtungssysteme.
