Die Kamerasysteme in den genannten bekannten Anwendungen sind abgestimmt auf die Anforderungen der speziellen Applikation und haben festgelegte Kameraeinstellungen. Da nun Kameras nach und nach immer weiter Einzug in Kraftfahrzeuge halten werden, um damit komplexere Fahrerassistenzfunktionen zu unterstützen, ist es aus wirtschaftlichen Gründen und Gründen des verfügbaren Bauraums geboten, dass ein einzelnes Kamerasystem für mehrere Fahrerassistenzfunktionen gleichzeitig genutzt wird.The Camera systems in the mentioned known applications are tuned to the requirements of the specific application and have specified Camera settings. Now cameras are gradually moving in in motor vehicles will be able to handle more complex driver assistance functions to support it is for economic reasons and reasons of available space, that a single camera system for multiple driver assistance functions used simultaneously.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Steuerung eines Kamerasystems eines Kraftfahrzeuges sowie einen entsprechenden Fahrerassistenten zu schaffen, so dass das Kamerasystem für verschiedene Fahrerassistenzapplikationen verwendet werden kann.Of the The invention is therefore based on the object, a method of control a camera system of a motor vehicle and a corresponding Driver assistants to create, so that the camera system for various driver assistance applications can be used.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie durch einen Fahrerassistenten mit den Merkmalen des Anspruchs 7 gelöst. Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.These The object is achieved by a method having the features of the claim 1 and by a driver assistant with the features of the claim 7 solved. Preferred embodiments of the invention are the subject of the dependent claims.
Das erfindungsgemäße Verfahren zur Steuerung eines Kamerasystems eines Kraftfahrzeugs, wobei mindestens eine Applikation eines Fahrerassistenzsystems auf der Auswertung der Bilder des Kamerasystems beruht, ordnet jeder Applikation des Fahrerassistenzsystems einen Parametersatz von Bildaufnahmeparametern zu, der zur Steuerung der Bildaufnahme des Kamerasystems verwendet wird. Damit wird für jede vom Fahrerassistenzsystem gerade ausgeführte Applikation der entsprechende Parametersatz in das Kamerasystem geladen und zur Ausführung gebracht, so dass das Kamerasystem die für die jeweilige Applikation notwendigen Bilder liefern kann.The inventive method for controlling a Camera system of a motor vehicle, wherein at least one application a driver assistance system on the evaluation of the images of the camera system rests, assigns each application of the driver assistance system one Parameter set of image acquisition parameters to, which is used to control image acquisition of the camera system is used. This will be for each of the Driver assistance system just running the application corresponding parameter set is loaded into the camera system and executed brought, so that the camera system those for the respective Application can provide necessary pictures.
Vorzugsweise enthält ein Parametersatz mindestens einen Bildaufnahmeparameter. Dabei können die folgenden Bildaufnahmeparameter in Frage kommen: die Belichtungszeit, der zu analysierende Bildausschnitt, die Abtastung des Bildes oder des gewünschten Bildausschnitts, die Reichweite und der Öffnungswinkel des Kamerasystems, der Zoomfaktor des Kamerasystems. Die Liste der aufgezählten Bildaufnahmeparameter des Kamerasystems erhebt dabei keinen Anspruch auf Vollständigkeit, weitere Bildaufnahmeparameter, wie Schwenkwinkel der Kamera seitwärts oder nach oben oder unten, Änderung der Bildaufnahme und der Abtastfrequenz des Kamerasystems fallen hier ebenfalls darunter. Mit anderen Worten, ein derartiger Parametersatz für eine Applikation des Fahrerassistenzsystems enthält die zur Steuerung der Kamera notwendigen Bildaufnahmeparameter.Preferably a parameter set contains at least one image acquisition parameter. The following image acquisition parameters can be used come: the exposure time, the image section to be analyzed, the scanning of the image or the desired image section, the range and the opening angle of the camera system, the zoom factor of the camera system. The list of enumerated Image acquisition parameters of the camera system makes no claim for completeness, other image acquisition parameters, such as Pan angle of the camera sideways or upwards or below, change the image recording and sampling frequency of the camera system are also covered here. In other words, contains such a parameter set for an application of the driver assistance system the image acquisition parameters necessary to control the camera.
Vorzugsweise sind die Parametersätze der einzelnen Applikationen unterschiedlich, wobei dies der Extremfall ist. Es kann sein, dass mehrere Applikationen für die Steuerung des Kamerasystems denselben Parametersatz verwenden, es kann jedoch auch sein, dass jede Applikation einen Parametersatz benötigt, der von allen anderen Parametersätzen unterschiedlich ist.Preferably are the parameter sets of the individual applications different, where this is the extreme case. It may be that multiple applications for the control of the camera system, the same parameter set However, it can also be that every application has one Parameter set required, that of all other parameter sets is different.
Vorzugsweise können die Bildaufnahmeparameter eines Parametersatzes einer Applikation variabel sein und beispielsweise eine Funktion der aktuellen Umgebungssituation sein. Dabei kommen als Umgebungssituationen Umgebungslichtbedingungen, Spurwechselsituationen, Kurvenfahrt des Kraftfahrzeugs, die Art der Straße, die Art der Spurmarkierung der Straße und die Art des Verkehrs, d. h., Stadtverkehr oder beispielsweise Autobahnverkehr, in Frage. Es ist offensichtlich, dass die Belichtungszeit der Kamera eine Funktion des Umgebungslichtes sein muss, da beispielsweise eine Kamera eine andere Belichtungszeit im Tunnel oder in der Dämmerung im Vergleich zum Tageslicht benötigt.Preferably, the image acquisition parameters of a parameter set of an application can be variable and, for example, be a function of the current environmental situation. Ambient lighting conditions, lane change situations, cornering of the motor vehicle, the type of road, the type of lane marking of the road and the type of traffic, ie City traffic or for example motorway traffic, in question. It is obvious that the exposure time of the camera must be a function of the ambient light, since, for example, a camera requires a different exposure time in the tunnel or at twilight compared to daylight.
Unter Applikationen eines Fahrerassistenzsystems werden vorzugsweise Fahrassistenzfunktionen verstanden.Under Applications of a driver assistance system are preferably driver assistance functions Understood.
Das erfindungsgemäße Fahrerassistenzsystem zur Durchführung des im voran gegangenen beschriebenen Verfahrens umfasst ein Kamerasystem zur Bereitstellung von Bilddaten für einzelne Applikationen des Fahrerassistenzsystems, wobei jeder Applikation, die auf einer Auswertung der Bilder des Kamerasystems beruht, ein Parametersatz vom Bildaufnahmeparametern zugeordnet ist, die zur Steuerung der Bildaufnahme des Kamerasystems dient. Weiter wird vorzugsweise das Kamerasystem durch eine Einzelkamera oder eine Stereo-Kamera-Anordnung gebildet.The Driver assistance system according to the invention for implementation of the method described above comprises a camera system for Provision of image data for individual applications the driver assistance system, with each application on one Evaluation of the images of the camera system is based, a parameter set is assigned by the image acquisition parameters that are used to control the Image recording of the camera system is used. Next is preferably the Camera system formed by a single camera or a stereo camera arrangement.
