Abstract

A device for optically recording the underbody of a vehicle using at least one camera, includes at least two mirrors which are disposed and oriented in such a way that images of several areas of the underbody of the vehicle are able to be recorded simultaneously by the camera.

Claims

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

at least one camera disposed to the side of a longitudinal axis of the vehicle so that a line of sight of the camera is perpendicular to the longitudinal axis of the vehicle; and

a plurality of mirrors disposed and oriented in such a way that images of several areas of the underbody of the vehicle are able to be recorded simultaneously by the camera when the vehicle is positioned over the device, wherein;

all of the mirrors are staggered with respect to each other in the longitudinal direction of the vehicle so that reflective surfaces of all the mirrors face the same direction and so that any axis running perpendicularly to the longitudinal axis of the vehicle intersects only one of the mirrors.

2. The device of claim 1, wherein at least two of the mirrors are disposed at an angle of 45°

relative to a top surface of the device.

3. The device of claim 1, wherein at least two of the mirrors are disposed at an angle not equal to 45°

relative to a top surface of the device.

4. The device of claim 1, wherein at least two of the mirrors are placed in such a way that at least one area of the underbody of the vehicle is able to be photographed by the camera from different perspectives when the vehicle is positioned over the device.

5. The device of claim 1, wherein the device is configured to construct an image of substantially an entirety of the underbody of the vehicle based on images projected by the mirrors to the camera in a first direction while an entirety of the vehicle passes over the device in a second direction essentially perpendicular to the first direction.

16. The device of claim 1, wherein from a perspective that includes a plane perpendicular to a direction of travel of the vehicle over the device and in which the line of sight of the camera is one of parallel to and coplanar with the plane, each mirror is oriented at the same angle as each other with respect to the line of sight of the camera.

17. The method of claim 1, wherein from a perspective that includes a plane perpendicular to a direction of travel of the vehicle over the device and in which the line of sight of the camera is one of parallel to and coplanar with the plane, each mirror is oriented at the same angle as each other with respect to the line of sight of the camera.

6. A method for optically recording images of an underbody of a vehicle moving over a device including a camera, comprising:

recording, by the camera, images of partial areas of the underbody of the vehicle, wherein the device includes a plurality of mirrors disposed and oriented in such a way that images of several areas of the underbody of the vehicle are simultaneously recordable by the camera when the vehicle is positioned over the device, wherein;

all of the mirrors are staggered with respect to each other in the longitudinal direction of the vehicle so that reflective surfaces of all the mirrors face the same direction and so that any axis running perpendicularly to the longitudinal axis of the vehicle intersects only one of the mirrors, and

the camera is disposed to the side of the longitudinal axis of the vehicle so that a line of sight of the camera is perpendicular to the longitudinal axis of the vehicle.

7. The method of claim 6, wherein different ones of the images are recorded in succession at a constant frequency.

8. The method of claim 6, further comprising:

assembling the images to form one overall image.

9. The method of claim 6, wherein the mirrors are offset relative to each other with respect to a longitudinal axis of the vehicle during the movement of the vehicle over the device.

10. The method of claim 9, wherein the mirrors are offset relative to each other with respect to a transverse axis of the vehicle during the movement of the vehicle over the device.

11. The method of claim 6, wherein the mirrors are offset relative to each other with respect to a transverse axis of the vehicle during the movement of the vehicle over the device.

12. The method of claim 6, wherein the mirrors are disposed at an angle of 45°

relative to the plane of the underbody of the vehicle during the movement of the vehicle over the device.

13. The method of claim 6, wherein the mirrors are disposed at an angle not equal to 45°

relative to the plane of the underbody of the vehicle during the movement of the vehicle over the device.

14. The method of claim 6, wherein at least two of the mirrors are placed in such a way that at least one area of the underbody of the vehicle is able to be photographed by the camera from different perspectives during movement of the vehicle in a single direction relative to the device.

15. The method of claim 6, wherein, during the movement of the vehicle over the device, the mirrors are disposed to project the images to the camera in a direction that is essentially perpendicular to the longitudinal axis of the vehicle.
