Embodiment Construction

[0030] The method according to the invention is preferably carried out by a driver assistance system which captures and displays a surround view around vehicle 10 by means of a plurality of cameras 1R, 1L, 1H, 1F. In this case, it is advantageous that the images captured by the cameras 1R, 1L, 1H, 1F have distinct intersection areas in which the area next to the vehicle is shown from different camera perspectives.

[0031] exist figure 1 A vehicle 10 with a device for generating a warning according to one specific embodiment is shown in .

[0032] A first camera 1R is arranged in the right exterior mirror 7 of the vehicle 10 and thus at a location outside the vehicle 10 . The first camera 1R is a wide-angle camera. The first camera 1R has a first optical axis 2R which is oriented parallel to the roadway surface 20 and at right angles to the longitudinal direction L of the vehicle 10 . The first optical axis 2R is the optical axis of the lens of the first camera 1R and is th...

Abstract

The invention relates to a device and a method for generating an alert. To this end, a first image of a vehicle environment of a vehicle (10) is obtained via a first camera (1R) from a first camera perspective, and a second image of the vehicle environment of the vehicle (10) is obtained via a second camera (1L) from a second camera perspective. The first camera (1R) and the second camera (1L) are two separate cameras arranged in external positions on the vehicle (10), and arranged at a distance from one another in a longitudinal direction (L) or a transverse direction (Q) of the vehicle (10). The first and the second images overlap in a first overlapping region (6, 6'). An item of positional information, defining a position of an object or a expected position of the object in relation to the vehicle (10), is provided in the first overlapping region (6, 6') based on the images of the first and second cameras (1R, 1L). An alert is emitted if the positional information falls in a predetermined alert region in relation to the vehicle (10).

Description

technical field [0001] The invention relates to a method and a device for generating a warning using two images of a vehicle surroundings captured by a camera. Background technique [0002] Driver assistance systems are used to support the driver of a motor vehicle. The support can be implemented in different ways. Thus, for example, the surroundings of the vehicle's immediate surroundings, which are also not in the driver's field of view, are usually displayed to the driver in order to avoid a collision. Furthermore, driver assistance systems are known which make the driver less active in control in order to increase user-friendliness for the driver. It is also possible to monitor the driver's control activity and to intervene in dangerous driving situations by the driver assistance system. Furthermore, driver assistance systems are known which allow autonomous driving of the vehicle without a driver. [0003] Camera-based driver assistance systems, which are able to de...
