Abstract

Provided is a method for determining a correctness of image data, the image data being captured by at least two cameras of a camera system installed at a vehicle. The method includes detecting at least one feature in the image data captured by a first one of the at least two cameras, determining if the at least one feature can be detected in the image data captured by a second one of the at least two cameras, and if the at least one feature can be detected in the image data captured by the second one of the at least two cameras, determining the correctness of the image data.

Claims (28)

1 . A method for determining a correctness of image data, the image data being captured by at least two cameras of a camera system installed at a vehicle, the method comprising:

detecting at least one feature in the image data captured by a first one of the at least two cameras;

determining whether the at least one feature is detectable in the image data captured by a second one of the at least two cameras;

upon determining that the at least one feature is detectable in the image data captured by the second one of the at least two cameras, determining the correctness of the image data; and

upon determining the correctness of the image data, increasing a safety integrity level of the at least one feature.

2 . The method according to claim 1 , wherein the image data are captured at a same time by the first one of the at least two cameras and the second one of the at least two cameras.

3 . The method according to claim 1 , wherein:

the at least two cameras comprise an at least partly overlapping field of view; and

only a part of the image data captured by the first one of the at least two cameras is used for detecting the at least one feature which corresponds to an area where a field of view of the first one of the at least two cameras overlaps with a field of view of the second one of the at least two cameras.

4 . The method according to claim 1 , wherein the at least one feature is at least one of a lane, a lane boundary, an object, or an obstacle.

5 . A control unit comprising a processor, wherein the control unit is configured to:

receive image data, the image data being captured by at least two cameras of a camera system installed at a vehicle;

detect at least one feature in the image data captured by a first one of the at least two cameras;

determine whether the at least one feature is detectable in the image data captured by a second one of the at least two cameras;

upon determining that the at least one feature is detectable in the image data captured by the second one of the at least two cameras, determine the correctness of the image data; and

upon determining the correctness of the image data, increase a safety integrity level of the at least one feature.

6 . The control unit according to claim 5 , wherein the control unit is further configured to output the camera data with the safety integrity level of ASIL B or higher.

7 . The control unit according to claim 5 , wherein the image data are captured at a same time by the first one of the at least two cameras and the second one of the at least two cameras.

8 . The control unit according to claim 7 , wherein the control unit is further configured to fuse image data captured by the first one of the at least two cameras and the second one of the at least two cameras.

9 . The control unit according to claim 8 , wherein the control unit is further configured to fuse the image data captured by the first one of the at least two cameras and the second one of the at least two cameras with respect to the at least one feature such that the at least one feature reaches a higher safety integrity level than before fusing.

10 . The control unit according to claim 5 , wherein:

the at least two cameras comprise an at least partly overlapping field of view, and

the control unit is configured to only use a part of the image data captured by the first one of the at least two cameras for detecting the at least one feature which corresponds to an area where a field of view of the first one of the at least two cameras overlaps with a field of view of the second one of the at least two cameras.

11 . The control unit according to claim 5 , wherein the at least one feature is at least one of a lane, a lane boundary, an object, or an obstacle.

12 . A control system comprising:

a camera system for a vehicle, the camera system comprising at least two cameras; and

the control unit according to claim 5 .

13 . A vehicle comprising the control system according to claim 12 , wherein the control unit is configured to control at least one of a longitudinal guide or a lateral guide of the vehicle based on the image data, upon determining the correctness of the image data.
