Abstract
Die Erfindung betrifft eine Stereokamera (2) zur Umgebungserfassung für ein Fahrzeug (1) mit zwei Kameraeinheiten (2.1, 2.2). Erfindungsgemäß sind die Kameraeinheiten (2.1, 2.2) vertikal übereinander in einem Fahrzeuginnenraum angeordnet, wobei zumindest ein hinter einem Objekt (O1) befindlicher Bereich ausschließlich von einer der Kameraeinheiten (2.2) erfassbar ist.The invention relates to a stereo camera (2) for detecting the surroundings of a vehicle (1) with two camera units (2.1, 2.2). According to the invention, the camera units (2.1, 2.2) are arranged vertically one above the other in a vehicle interior, wherein at least one area located behind an object (O1) can be detected exclusively by one of the camera units (2.2).
Description
Die Erfindung betrifft eine Stereokamera zur Umgebungserfassung für ein Fahrzeug mit zwei Kameraeinheiten.The invention relates to a stereo camera for environmental detection for a vehicle with two camera units.
Aus der
Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Stereokamera zur Umgebungserfassung für ein Fahrzeug anzugeben.The invention is based on the object of specifying a comparison with the prior art improved stereo camera for environmental detection for a vehicle.
Die Aufgabe wird erfindungsgemäß gelöst durch eine Vorrichtung, welche die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved by a device having the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Stereokamera zur Umgebungserfassung für ein Fahrzeug umfasst zwei Kameraeinheiten, wobei erfindungsgemäß die Kameraeinheiten vertikal übereinander in einem Fahrzeuginnenraum angeordnet sind und zumindest ein hinter einem Objekt befindlicher Bereich ausschließlich von einer der Kameraeinheiten erfassbar ist.The stereo camera for environmental detection for a vehicle comprises two camera units, wherein according to the invention the camera units are arranged vertically above one another in a vehicle interior and at least one area located behind an object can be detected exclusively by one of the camera units.
Die Stereokamera ermöglicht eine Erfassung erhabener Objekte auf einer Fahrbahnoberfläche, wobei aufgrund der geometrischen Anordnung der Kameraeinheiten keine Disparitätsbestimmung erforderlich ist. Insbesondere ermöglicht die Stereokamera in besonders einfacher Weise, erhabene, nicht klassifizierbare Objekte in großer Entfernung zu erkennen. Dies ist besonders vorteilhaft bei einer Verwendung mittels der Stereokamera erfasster Daten für einen autonomen Fahrbetrieb eines Fahrzeugs, wobei beispielsweise ein automatisches Bremsen und Ausweichen auf erfasste Objekte auf Autobahnen vereinfacht ist.The stereo camera allows detection of raised objects on a road surface, whereby due to the geometric arrangement of the camera units no disparity determination is required. In particular, the stereo camera allows in a particularly simple manner to detect raised, non-classifiable objects at a great distance. This is particularly advantageous when using data acquired by means of the stereo camera for autonomous driving operation of a vehicle, wherein, for example, automatic braking and avoidance of detected objects on highways is simplified.
