Abstract

A method is described for detecting a traffic space comprising a driver assistance system including a monocular image sensor. The image sensor produces chronologically successive images of the traffic space. The images of the image sequence are used to ascertain the visual flow and examine it for discontinuities. Discontinuities found in the visual flow are assigned to objects in the traffic space.

Claims

1-12. -12. (canceled)

13. A method for detecting a traffic space using a driver assistance system having a monocular image sensor (12), the method comprising:

generating, using the monocular image sensor, chronologically successive images of the traffic space;

ascertaining the visual flow in the individual images;

examining the visual flow for discontinuities; and

assigning discontinuities found in the visual flow to objects of the traffic space.

14. The method of claim 13, wherein obstructions in the traffic space are inferred from a location of the discontinuities.

15. The method of claim 13, wherein a moving object is inferred from a change of a location of the discontinuities of the visual flow.

16. The method of claim 13, wherein a condition of the terrain next to the road is inferred from detected discontinuities of the visual flow.

17. The method of claim 13, wherein identified discontinuities of the visual flow are used to control the driver assistance system and any necessary and additional on-board systems.

18. The method of claim 13, wherein discontinuities of the visual flow are used in connection with warning strategies.

19. The method of claim 13, wherein warnings derived from discontinuities of the visual flow are fed into the driver information system.

20. The method of claim 13, wherein warnings derived from discontinuities of the visual flow are inserted into a night view image of the driver assistance system.

21. The method of claim 13, wherein information derived from a discontinuity of the visual flow is used for controlling a passenger protection system.

22. The method of claim 13, wherein information derived from a discontinuity of the visual flow is used for a precrash detection system.

23. The method of claim 13, wherein information derived from a discontinuity of the visual flow is used for lane detection and lane guidance of the vehicle.

24. The method of claim 13, wherein information derived from a discontinuity of the visual flow is used for plausibility testing of sensors to improve their measuring accuracy.
