Abstract

A device for monitoring an environment of a vehicle, wherein the environment is captured via of a plurality of image capturing units, the capture ranges (2) thereof at least partially overlapping each other and forming an overlap range (3). An overall image is generated from the individual images captured via the image capturing units using an image processing unit, the overall image showing the vehicle and the environment thereof from a bird'"'"'s-eye view. The image capturing units are wafer-level cameras (1).

Claims

1. A device for monitoring an environment of a vehicle, wherein the environment is captured by means of a plurality of image capturing units, the capture ranges (2) thereof at least partially overlapping each other and forming an overlap range (3), wherein an overall image is generated from the individual images captured by means of the image capturing units by means of an image processing unit, which overall image shows the vehicle and the environment thereof from a bird'"'"'s-eye view,

wherein the image capturing units are wafer-level cameras (1),

wherein several wafer-level cameras (1) are arranged parallel adjacent to each other in the form of a line,

wherein the wafer-level cameras 1 of a line are equipped with optical lenses (4) having different focal widths, and

wherein the image processing unit selects different wafer-level cameras 1 to obtain images with different focal widths.

2. The device according to claim 1, wherein the wafer-level cameras (1) are arranged at the sides of a vehicle body in an integrated manner.

3. The device according to claim 1, wherein two wafer-level cameras (1) of a line simultaneously record an image and transfer it to the image processing unit.

4. The device according to claim 1, wherein the a display device for depicting the overall image is provided.

5. The device according to claim 1, wherein the image processing unit is arranged in the immediate spatial proximity to the wafer level cameras (1) in the vehicle.
