Beschreibung von AusführungsbeispielenDescription of exemplary embodiments
Nachfolgend wird eine Vorrichtung für ein Kraftfahrzeug mit einer im nahen infraroten Spektralbereich empfindlichen Kamera und einer Wärmebildkamera beschrieben, wobei die im nahen infraroten Spektralbereich empfindliche Kamera und die Wärmebildkamera im Wesentlichen dieselbe Szene erfassen und ein Stereokamerasystem bilden. Ferner werden ein Kraftfahrzeug und ein Verfahren zur Erzeugung von Bildsignalen in einem Kraftfahrzeug beschrieben.following is a device for a motor vehicle with an im near infrared spectral sensitive camera and one Thermal imager described, where in the near infrared spectral range delicate camera and the thermal imaging camera in essence capture the same scene and form a stereo camera system. Further will be a motor vehicle and a method for generating image signals described in a motor vehicle.
Im bevorzugten Ausführungsbeispiel stellen die im nahen infraroten Spektralbereich empfindliche Kamera, die Wärmbildkamera und die Auswerteeinheit einzelne Komponenten dar, die an jeweils unterschiedlichen Orten des Kraftfahrzeugs angeordnet sind. In einer Variante des bevorzugten Ausführungsbeispiels sind sowohl die nahen infraroten Spektralbereich empfindliche Kamera, die Wärmbildkamera als auch die Auswerteeinheit in einer einzelnen Einheit integriert und an einem Ort des Kraftfahrzeuges, vorzugesweise hinter der Windschutzscheibe oder im Stoßfänger, angeordnet. Es sind alle Varianten denkbar, so dass die Varianten von drei vollständig getrennten Komponenten bis zu einer einzelnen kompakten Einheit reichen.in the preferred embodiment, the in the near infrared Spectral range sensitive camera, the thermal imaging camera and the evaluation unit is a single component connected to each are arranged in different places of the motor vehicle. In a Variant of the preferred embodiment are both the near infrared spectral range sensitive camera, the thermal imaging camera as also the evaluation unit integrated in a single unit and in a place of the motor vehicle, preferably behind the windshield or in the bumper. All variants are conceivable so that the variants of three completely separate components to a single compact unit.
In einer Variante des bevorzugten Ausführungsbeispiels umfasst die Vorrichtung zusätzlich zur im nahen infraroten Spektralbereich empfindlichen Kamera und der Wärmebildkamera eine im sichtbaren Spektralbereich empfindliche Kamera. Vorzugsweise erfasst die im sichtbaren Spektralbereich empfindliche Kamera im Wesentlichen dieselbe Szene wie die im nahen infraroten Spektralbereich empfindlichen Kamera und/oder die Wärmebildkamera. Alternativ zur Anzeige von Bildern der im nahen infraroten Spektralbereich empfindlichen Kamera werden Bilder der im sichtbaren Spektralbereich empfindlichen Kamera über die Anzeigeeinheit angezeigt. In einer weiteren Variante werden auf den angezeigten Bildern Objekte, die vom eigenen Kraftfahrzeug gefährdet werden oder die eine Gefahr für den Fahrer oder das Kraftfahrzeug darstellen, entsprechend gekennzeichnet.In a variant of the preferred embodiment, in addition to the camera which is sensitive in the near infrared spectral region and the thermal imaging camera, the device also comprises a visible light spectral sensitive camera. Preferably, the sensitive in the visible spectral range camera captures substantially the same scene as the sensitive in the near infrared spectral range camera and / or the thermal imaging camera. As an alternative to displaying images of the camera sensitive in the near infrared spectral range, images of the camera sensitive in the visible spectral range are displayed via the display unit. In a further variant, objects which are endangered by one's own motor vehicle or which represent a danger to the driver or the motor vehicle are identified accordingly on the displayed images.
Zusätzlich ist vorgesehen, dass nicht nur der Abstand des Objekts zum Kraftfahrzeug sondern auch die Zeit bis zum Aufprall des Objektes auf das Kraftfahrzeug ermittelt wird. In Abhängigkeit der ermittelten Zeit bis zum Aufprall des Objektes auf das Kraftfahrzeug wird eine Warnung an den Fahrer ausgegeben und/oder entsprechende Stellbefehle, beispielsweise zum Verzögern des Kraftfahrzeuges, erzeugt.additionally It is envisaged that not only the distance of the object to the motor vehicle but also the time until the impact of the object on the motor vehicle is determined. Depending on the determined time to the impact of the object on the vehicle is a warning issued to the driver and / or corresponding control commands, for example for decelerating the motor vehicle generated.
In einer weiteren Variante ist zusätzlich vorgesehen, dass die Auswerteeinheit Signale von weiteren Kraftfahrzeugsensoren, beispielsweise von Inertialsensoren und/oder von Geschwindigkeitssensoren, erhält und auswertet.In a further variant is additionally provided that the evaluation unit signals from further motor vehicle sensors, for example, inertial sensors and / or speed sensors, receives and evaluates.
