Abstract

Die Erfindung betrifft ein Kamerasystem und ein Verfahren zur Steuerung des Kamerasystems zur Aufnahme von Bildern einer Umgebung eines Fahrzeugs für ein Fahrerassistenzsystem des Fahrzeugs.Das Kamerasystem umfasst eine erste Rolling-Shutter Kamera (1) mit einem ersten Öffnungswinkel α, eine zweite Rolling-Shutter Kamera (2) mit einem zweiten Öffnungswinkel β und eine Steuerungselektronik. Die erste Kamera (1) ist zur Erzeugung eines Weitwinkelkamerabilds geeignet, d.h. der erste Öffnungswinkel α ist größer als der zweite Öffnungswinkel β der zweiten Kamera (2), die zur Erzeugung eines Telekamerabilds geeignet ist. Die beiden Kameras (1, 2) sind derart konfiguriert, dass beide Kamerabilder einen Überlappungsbereich aufweisen. Die Steuerungselektronik ist dazu ausgebildet, dass eine Synchronisierung der beiden Kameras (1, 2) erfolgt. Die geometrische Anordnung der beiden Kameras (1, 2) zueinander und die Lage des Überlappungsbereichs (10) im Weitwinkelbild und im Telekamerabild werden durch eine kontinuierliche Schätzung ermittelt. Die gespeicherte geometrische Anordnung und Lage werden bei der Synchronisierung der ersten (1) und der zweiten (2) Kamera des Kamerasystems berücksichtigt.
