Abstract

A recording device for recording images of an underbody of a vehicle includes: at least one camera recording images of areas of the underbody; and mirrors situated to project images of the underbody into the at least one camera. The mirrors are situated in such a way that the mirrors project adjoining areas of the underbody transversely to the driving direction of the vehicle into the camera as image areas situated one above the other.

Claims

1. A recording device for recording images of an underbody of a vehicle, comprising:

at least one camera configured to record images of areas of the underbody; and

mirrors arranged to project images of areas of the underbody into the at least one camera, wherein the mirrors are situated to project adjoining areas of the underbody transversely to the driving direction of the vehicle simultaneously into the camera as image areas, the image areas being stacked one above the other, each of the mirrors projecting into a different one of the stacked image areas relative to one another.

2. The recording device as recited in claim 1, wherein the mirrors are situated in such a way to extend the visual path between the at least one camera and the underbody of the vehicle.

3. The recording device as recited in claim 2, wherein the mirrors are situated in such a way to utilize installation space transversely to the driving direction of the vehicle, in order to extend the visual path between the at least one camera and the underbody of the vehicle.

4. The recording device as recited in claim 2, wherein the mirrors are situated in such a way to utilize installation space parallel to the driving direction of the vehicle, in order to extend the visual path between the at least one camera and the underbody of the vehicle.

5. The recording device as recited in claim 2, wherein the camera and the mirrors are situated in a drive-over channel configured to be driven over by the vehicle to be recorded.

6. The recording device as recited in claim 5, wherein the drive-over channel is sealed by a cover having an opening facing the underbody of the vehicle, the opening extending essentially transversely to the driving direction of the vehicle.

7. A method for recording images of an underbody of a vehicle, comprising:

providing a recording device including;

at least one camera configured to record images of areas of the underbody; and

mirrors arranged to project images of areas of the underbody into the at least one camera, wherein the mirrors are situated to project adjoining areas of the underbody transversely to the driving direction of the vehicle simultaneously into the camera as image areas, the image areas being stacked one above the other, each of the mirrors projecting into a different one of the stacked image areas relative to one another; and

driving over the recording device with the vehicle.

8. The method as recited in claim 7, further comprising:

detecting areas associated with the underbody of the vehicle in the recorded images; and

only using the detected areas associated with the underbody for evaluation.

9. A method for recording images of an underbody of a vehicle comprising:

providing a recording device including;

at least one camera configured to record images of areas of the underbody; and

mirrors arranged to project images of areas of the underbody into the at least one camera, wherein the mirrors are situated to project adjoining areas of the underbody transversely to the driving direction of the vehicle into the camera as image areas situated one above the other;

driving over the recording device with the vehicle;

detecting areas associated with the underbody of the vehicle in the recorded images;

only using the detected areas associated with the underbody for evaluation;

calculating a visual flow between chronologically consecutive images; and

only using areas of the images in which flow vectors are found for evaluation.
