Abstract

This paper presents an overview of a hybrid test strategy for ADAS functions testing and validation. The hybrid test strategy represents a combination of real and virtual validation procedure providing a substitute to elaborate real tests in the development process. ADAS sensor – front view camera – modeling approaches are presented where the causes of relevant optical aberrations and their effects on the acquired images are investigated. In this context, distortion, blur and vignetting models are created and demonstrated. Additionally, a toolchain, a method for camera simulation and testbed setups are defined and presented as enablers for hybrid test strategies.

Zusammenfassung

Dieser Beitrag gibt einen Überblick über eine hybride Teststrategie für das Testen und Validieren von ADAS-Funktionen. Die hybride Teststrategie stellt eine Kombination aus realem und virtuellem Validierungsverfahren dar, die einen Ersatz für die Ausarbeitung realer Tests im Entwicklungsprozess darstellt. ADAS-Sensor – Frontsichtkamera – Modellierungsansätze werden vorgestellt, bei denen die Ursachen relevanter optischer Aberrationen und deren Auswirkungen auf die aufgenommenen Bilder untersucht werden. In diesem Zusammenhang werden Verzerrungs-, Unschärfe- und Vignettierungsmodelle erstellt und demonstriert. Zusätzlich werden eine Werkzeugkette und Methode für Kamerasimulation sowie Prüfstandsaufbauten definiert und als Enabler für hybride Teststrategien vorgestellt.
