Abstract

A scattered light trap for a camera of a mobile unit includes a scattered-light-reducing structure that has rising plane surfaces and falling surfaces that repeat alternatingly in a direction of a light beam incident on the camera, the angles between the rising plane surfaces and a plane of motion of the mobile unit differing at least partially or corresponding to the largest possible angle as a function of specified criteria.

Claims

1-10. -10. (canceled)

11. A scattered light trap for a camera of a mobile unit, the scattered light trap comprising:

a scattered-light-reducing structure that includes rising plane surfaces and falling surfaces that repeat alternatingly in a direction of a light beam incident on the camera, wherein, as a function of specified parameters, angles between the rising plane surfaces and a plane of motion of the mobile unit differ at least partially or correspond to a largest possible angle.

12. The scattered light trap of claim 11, wherein the specified parameters include at least one of:

at least one specified structural parameter;

at least one specified camera parameter; and

at least one specified characterizing parameter of the mobile unit.

13. The scattered light trap of claim 12, wherein, in a direction of an objective of the camera, the angles between the rising plane surfaces and the plane of motion of the mobile unit increase at least partially or correspond to the largest possible angle, determined according to specified criteria as a function of a distance between the respective, rising plane surfaces and the objective of the camera.

14. The scattered light trap of claim 12, wherein, in a direction of an objective of the camera, an extension of the rising plane surfaces decreases at least partially or corresponds to a smallest possible extension determined according to specified criteria as a function of a distance of the respective, rising surface to the objective.

15. The scattered light trap of claim 11, wherein the specified parameters include at least one specified characterizing parameter of the mobile unit with respect to a type of construction of the mobile unit.

16. The scattered light trap of claim 11, wherein the specified parameters include at least one specified structural parameter that is a function of at least one of:

a position of the rising surfaces relative to the scattered-light-reducing structure;

a position of the rising surfaces relative to the mobile unit;

a variation of the rising surfaces of the structure relative to the camera; and

a variation of the rising surfaces of the structure relative to the mobile unit.

17. The scattered light trap of claim 11, wherein the specified parameters include at least one specified characterizing parameter of the mobile unit that is a function of an angle of inclination of the windshield of the mobile unit.

18. The scattered light trap of claim 11, wherein the specified parameters include at least one specified camera parameter that is a function of the field of view of the camera.

19. The scattered light trap of claim 11, wherein the falling surfaces have a shape that is concave, convex, or undulating.

20. The scattered light trap of claim 11, wherein the falling surfaces have a concave or convex shape, curvatures of the falling surfaces being a function of specified radii of curvature.

21. The scattered light trap of claim 11, wherein the falling surfaces have a concave or convex shape, curvatures of the falling surfaces being a function of specified at radii of curvature that at least partially differ from each other.
